The most important answers in two minutes

If you have recently been recommended for a hip or knee replacement, you are probably in a situation that many people find stressful.

Perhaps you have spent years trying to alleviate your symptoms with physiotherapy, painkillers, or injections. Perhaps you have hoped to avoid surgery for many years to come. And now, for the first time, you hear the sentence:

"An artificial joint would probably be the best solution."

This moment often raises more questions than it answers.

Is surgery really necessary?

Can I wait a little longer?

Which prosthesis is the right one?

How do I find an experienced surgeon?

What are the risks?

And will I be able to live the way I used to afterwards?

The good news is:

Modern hip and knee replacements are among the most successful procedures in all of medicine today.

Every year, millions of people worldwide regain their mobility, independence, and quality of life.

At the same time, however, the following also applies:

Not every patient needs immediate surgery.

Not every prosthesis is suitable for every person.

Not every clinic operates according to the same philosophy.

And that's precisely why it's worthwhile to gather comprehensive information before making this decision.

This guide is designed to help you.

First, an important message

If you are reading this article right now, you have probably already come a long way.

Most people don't wake up in the morning and decide to have an artificial hip or knee joint implanted.

Usually, it all starts much earlier.

Perhaps accompanied by a pulling sensation in the groin.

I experience knee pain when climbing stairs.

With discomfort after longer walks.

Or with the realization that things that used to be taken for granted suddenly become strenuous or even impossible.

Many patients initially try everything to avoid surgery.

They are undergoing physiotherapy.

They are taking painkillers.

You will receive injections.

They reduce sporting activities.

They change their shoes.

They are losing weight.

They are trying dietary supplements.

Some people live with the pain for years.

Often, the duration is significantly longer than would be medically advisable.

Therefore, I would like to share a thought with you right at the beginning, one that I often tell my patients in the first conversation:

A hip or knee replacement is not a sign of failure.

It often marks the beginning of a new, less painful phase of life.

This perspective changes many things.

Because the goal of modern endoprosthetics is not to improve an X-ray image.

The goal is to give you back your life.

The comprehensive hip and knee check: Do you need a hip or knee replacement?

The most important question of all

Do I really need to have surgery?

In my view, this question is more important than any other.

Surprisingly, the answer is not automatically:

Yes.

Although I have specialized in hip and knee replacement surgery for many years, my recommendation is by no means always "surgery".

Why?

Because timing is crucial.

Surgery performed too early may be unnecessary.

Surgery performed too late can also have disadvantages.

The trick is finding the right time.

And that is precisely why consultation with a specialized endoprosthetician is so important.

When is a hip or knee replacement recommended?

This question cannot be answered based solely on an X-ray image.

Many people are surprised to learn that some patients have hardly any pain despite pronounced osteoarthritis, while others are severely restricted even with comparatively moderate changes.

Therefore, today we are not only looking at the joint.

We consider the whole person.

Surgery is typically considered when several factors coincide.

Pain

The pain no longer occurs only occasionally.

They increasingly accompany you in your everyday life.

You may no longer be able to take longer walks.

You might wake up during the night.

Perhaps you already find it difficult to put on your shoes.

Or you avoid stairs, shopping, or traveling.

Reduced quality of life

For many patients, this is even the most important point.

The X-ray image is not the deciding factor.

But the question is:

What can you no longer do today that used to bring you joy?

Go for a stroll?

Golf?

Ride a bike?

Hike?

Dance?

Playing with the grandchildren?

Work?

The ultimate goal of a prosthesis is to restore this quality of life to you as much as possible.

Exhausted conservative therapy

Before surgery, all sensible conservative treatment options should have been considered.

Examples include:

• Physical therapy
• targeted muscle training
• Weight reduction (if appropriate)
• Pain therapy
• Exercise programs
• Injections in selected situations
• Adapting to everyday stresses

If these measures no longer bring sufficient improvement, surgical therapy becomes more important.

Imaging

Of course, the X-ray image also plays an important role.

It helps us to understand,

• how far the joint wear has progressed,
• which parts of the joint are affected,
• whether malpositions exist,
• which implant concepts might be suitable.

But once again:

An X-ray alone won't perform surgery on anyone.

We perform surgery on people.

No pictures.

One sentence that changes everything

Many patients ask me:

"Professor, would you have surgery if you were in my shoes?"

I often reply:

"I would only have surgery if my quality of life suffered more permanently from the osteoarthritis than from the thought of the operation."

This sentence summarizes the core of modern endoprosthetics remarkably well.

Because the decision is not based on the calendar.

Not according to age.

Not based on the X-ray image.

But after your life.

Do I need to have surgery immediately – or can I wait?

Perhaps the most important decision on the way to a hip or knee replacement

If you have been recommended for a hip or knee replacement for the first time, your first reaction is probably not:

"When can I have surgery?"

But rather:

"Isn't there another way to do it without surgery?"

This reaction is completely understandable.

Ultimately, it's a procedure most people never wanted. Many still associate joint replacement with large incisions, long hospital stays, pain, and months of rehabilitation.

Modern endoprosthetics has developed considerably in recent years.

Nevertheless, the question remains valid:

Do I need to have surgery now – or can I wait?

The answer is:

It depends on.

And that is precisely why an individual assessment is so important.

There is no fixed rule

Many patients hope for a simple answer.

For example:

"From grade 4 osteoarthritis onwards, everyone needs a prosthesis."

Or:

"At 60, you should still wait."

Or:

"A prosthesis only lasts 15 years, therefore surgery should be performed as late as possible."

Unfortunately, such sweeping statements are not true.

The decision never depends on just one single factor.

It results from the interplay of:

• Your complaints,
• Your quality of life,
• your activity level,
• Their age,
• their bone quality
• the X-ray findings,
• Your personal goals,
• and your general health.

Therefore, two patients with almost identical X-ray images can receive completely different recommendations.

The crucial question is not:

How bad does my X-ray look?

Rather:

How much does my joint really restrict me in everyday life?

This distinction is extremely important.

I regularly see patients with almost completely worn-out hip joints who are still surprisingly active and have only minor complaints.

Similarly, I see patients with comparatively moderate changes who can hardly sleep at night, can no longer walk 200 meters and have almost completely lost their quality of life.

That's why we treat people.

Not X-rays.

When are there strong arguments for waiting?

There are certainly situations in which an artificial joint is not yet the right next step.

For example, if:

• Their pain only occurs occasionally.
• They are hardly restricted in their daily lives.
• They can easily go for a walk.
• They sleep pain-free at night.
• Conservative measures can still be very helpful.
• that your symptoms do not worsen.
• Although the osteoarthritis is visible, your quality of life is hardly affected.

In such cases, it may be advisable to continue observing the situation for a while.

However, that doesn't mean doing nothing.

On the contrary.

Right now, targeted muscle training, weight reduction, exercise programs and an adapted workload can often make a big difference.

When does further waiting become problematic?

This question is asked far less frequently.

It is at least as important.

Many patients understandably want to avoid surgery for as long as possible.

However, some people wait so long that osteoarthritis dominates their entire lives.

They are foregoing holiday travel.

They stop hiking.

They hardly ever climb stairs anymore.

They meet friends less often.

They sleep poorly.

They are moving less and less.

And this is precisely where a vicious cycle often begins.

Osteoarthritis does not only affect the joint

Many people think:

"My hip hurts."

In fact, advanced osteoarthritis often changes the entire body.

Patients begin to limp unconsciously.

They relieve the painful leg.

The muscles gradually deteriorate.

The fitness level is declining.

The balance is deteriorating.

Back pain develops.

The other knee or hip will be subjected to greater stress.

Over time, general physical activity often decreases significantly.

And these changes cannot always be completely reversed later.

Why the right time for surgery is so important

Modern endoprosthetics pursues a different goal today than it did twenty years ago.

The recommendation used to be:

"Hold on as long as possible."

Today we know:

Surgery performed too late can also have disadvantages.

Patients who have already lost a significant amount of muscle mass, can barely move, or have changed their entire lifestyle due to pain often require a longer rehabilitation period.

That doesn't mean the result has to be worse.

But the road back to an active life can be significantly longer.

Therefore, the goal is not to operate as early or as late as possible.

It's about finding the right time

A simple self-test

Ask yourself the following questions:

Has my daily routine changed in the last twelve months?

• I go for walks much less often.
• I avoid long distances.
• I ride my bike less often.
• I no longer do any sports.
• I get up at night because of pain.
• I need painkillers regularly.
• I find it difficult to put on shoes or socks anymore.
• I'm planning holidays after my arthritis treatment.
• I decline invitations because of my health problems.
• I feel like my life has become smaller.

If you answer several of these questions with "yes" , specialized advice is worthwhile.

Not necessarily, because surgery is required immediately.

But because you should discuss with an experienced endoprosthetics specialist what time makes sense for you personally.

Should I be afraid of missing the right moment?

I hear this concern frequently.

The good news is:

In most cases, there is enough time to make an informed decision.

You don't have to commit within a few days.

Take your time,

• Ask your questions,
• to obtain a second opinion,
• to learn about different treatment options
• and to develop the best strategy for you together with your surgeon.

A good decision is rarely made under pressure.

My personal advice

When patients ask me when they should have surgery, I often answer:

"The X-ray doesn't determine the right time. What matters is when your osteoarthritis starts taking your life."

Because that's exactly what it's about.

A modern hip or knee replacement should do more than just relieve your pain.

It should enable you to

to travel again

to do sports again,

to go for a walk again without thinking,

to play on the floor with your grandchildren again,

to climb stairs again

to regain quality of life.

And that is precisely why the decision should not be made out of fear of surgery or fear of a prosthesis.

It should be based on an individual, well-informed assessment.

Expert tip

Don't wait until you "can't go on anymore".

The goal of modern endoprosthetics is not to implant an artificial joint as late as possible.

The goal is to give you back as many active and pain-free years of life as possible.

How do I find the right specialist for a hip or knee replacement?

Not every clinic is the same – and not every surgeon works according to the same philosophy

Anyone searching for a hip or knee replacement on the internet today will be confronted with hundreds of offers within minutes.

Almost every clinic advertises with state-of-the-art surgical procedures.

Almost every surgeon calls themselves a specialist.

Many websites promise short incisions, fast rehabilitation and state-of-the-art implants.

It is therefore understandably difficult for patients to recognize,

in what way the individual centers actually differ.

This decision is of great importance.

Because a hip or knee prosthesis often accompanies you for many decades.

Choosing the right surgeon is therefore one of the most important medical decisions you will make in your life.

What makes a good endoprosthetics specialist?

Many patients initially believe:

"The main thing is that the operation is performed technically correctly."

Of course, precise surgery is crucial.

But the real quality begins much earlier.

A high-quality endoprosthetic treatment encompasses much more than the actual procedure.

It begins with the initial consultation.

An experienced specialist takes his time,

To understand your symptoms,

To understand your expectations,

to carefully analyze their imaging,

to answer your questions in detail

and to decide together with you,

whether an operation is even necessary.

The operation itself is then merely one component of a significantly larger treatment concept.

Specialization is more important than size

Many people automatically assume that

that large hospitals generally achieve better results.

In reality, the question is more nuanced.

The size of a clinic is less important.

Specialization is crucial.

A center that deals intensively with hip and knee endoprosthetics on a daily basis develops standardized procedures, well-coordinated teams, and special experience with a wide variety of patient situations over the years.

This routine does not only affect the surgeon.

It also includes

• the anesthesia,
• the operating team,
• the care,
• physiotherapy,
• the rehabilitation
• and the entire organization.

The better these areas work together,

The smoother your treatment usually goes, the better.

Experience is worth more than many operations

Patients often ask:

"How many prostheses should a surgeon have performed?"

There is no fixed number.

Experience means far more than the number of procedures.

This is evident, for example, in the fact that

how carefully the indication for surgery is determined,

how individually implants are selected,

how complex anatomical situations are solved,

how complications can be avoided

and how patients are supported even after the operation.

An experienced specialist often recognizes details during the initial consultation

which can significantly influence the later success of the treatment.

Good advice can be recognized by the questions asked

An interesting sign of quality is not,

how much a doctor talks.

But rather the questions he asks.

For example, a specialist might want to know:

• What are the main complaints?
• Which activities would you like to resume?
• What surgeries have you already had?
• How active are you professionally?
• What are your sporting goals?
• What are your expectations of a prosthesis?
• What worries you?

These questions will help you

to tailor the treatment to your individual everyday life.

Because a 48-year-old tennis player,

a 68-year-old hiker

and an 82-year-old patient

Despite similar osteoarthritis, patients often require different treatment approaches.

Not every prosthesis is suitable for every person

Many patients still believe that

There would be "the best hip prosthesis" or "the best knee implant".

Unfortunately, it's not that simple.

Modern endoprosthetics takes a different approach today.

The focus is not on the prosthesis.

The focus is on the individual.

Age,

Bone quality,

Anatomy,

Activity level,

body weight,

Profession,

Sports

and personal expectations

influence the choice of the appropriate implant.

Therefore, the choice of implant should never be based on the motto

"We use this prosthesis for every patient."

take place.

It should always be done on an individual basis.

Science instead of habit

Endoprosthetics is constantly evolving.

New implants,

new surgical procedures,

improved materials,

digital planning options

and modern rehabilitation concepts change the treatment a little bit every year.

A specialized surgeon therefore continuously engages with scientific developments.

Not every innovation is automatically better.

But equally, not every proven method is optimal for every patient.

Good medicine originates there,

where scientific findings,

clinical experience

and individual patient needs are brought together.

Modern endoprosthetics is teamwork

Many patients focus exclusively on the surgeon.

That's understandable.

In reality, however, the success of the treatment depends on the entire team.

High-quality care includes, among other things:

• experienced anesthesiologists,
• specialized surgical nursing,
• structured pain therapy,
• Physiotherapy from day one,
• individual rehabilitation,
• Follow-up checks,
• long-term care.

The better these areas interact, the better the

The safer and more pleasant the entire treatment will be.

What you should pay attention to in the initial consultation

Many patients leave an initial consultation with an uneasy feeling

without being able to specify exactly why.

Therefore, I recommend asking yourself the following questions after the appointment:

Did I feel understood?

Were my questions answered sufficiently?

Did the doctor take his time?

Were the different treatment options explained?

Was it explained why exactly this recommendation was made?

Were any potential disadvantages also openly discussed?

Do I have confidence?

The last point in particular is often underestimated.

A hip or knee replacement is a joint decision between the patient and the surgeon.

This decision should be based on trust.

Why a second opinion can be useful

Many patients are worried,

that a second opinion could be interpreted as mistrust.

The opposite is true.

A well-founded second opinion is an expression of a responsible approach to an important medical decision.

She can help,

To eliminate uncertainties,

to demonstrate treatment alternatives,

to better assess the timing of the operation

or to confirm the original recommendation.

And sometimes the greatest value of a second opinion lies precisely in this,

that it gives you the security,

to continue down the path already taken with a good feeling.

My personal advice

If you are looking for a specialist,

Don't ask yourself first:

"Who promises the most modern prosthesis?"

Instead, ask:

"Which doctor makes me feel that my individual situation is truly understood?"

Because modern endoprosthetics does not begin with an implant.

It begins with listening.

With understanding.

And with a joint decision.

Which hip prosthesis is right for me?

Why there is no one perfect hip prosthesis

When patients first hear that they may need an artificial hip joint, they almost always ask the same question:

"Which hip prosthesis is actually the best?"

This question is perfectly understandable.

Ultimately, every patient wants to receive the most modern, durable, and safest solution.

The surprising answer, however, is:

There is no single best hip prosthesis.

At least not as a universally valid answer.

Because the prosthesis does not determine the success of the treatment.

The crucial factor is how well a prosthesis fits your body, your anatomy, and your personal requirements.

Modern endoprosthetics therefore means one thing above all today:

Individualization.

Every person is different

No two hip joints are exactly alike.

There are differences in

• bone quality
• the shape of the femur,
• the position of the pelvis,
• the muscles,
• height
• body weight
• mobility,
• the activity level
• and personal expectations.

A 45-year-old triathlete has different requirements for a hip prosthesis than an 82-year-old patient whose most important goal is pain-free walking in everyday life.

Both can achieve excellent results.

But often not with the same implant concept.

Modern philosophy states:

The patient does not have to fit the prosthesis.

The prosthesis must fit the patient.

This idea changes the entire treatment.

Previously, a few standard systems were often used for almost all patients.

Today, numerous implant concepts are available.

The art lies in selecting the most individually appropriate solution for each patient.

What factors influence the choice of implant?

Before any operation, the following questions, among others, should be answered:

How old are you?

Biological age is often more important than the date of birth.

A very active 70-year-old may have different requirements than a significantly younger patient with low physical activity.

How active would you like to be after the operation?

Would you like to

• go for a stroll,
• hike,
• Ride a bike,
• Golf,
• Play tennis,
• To ski,
• jog,
• or simply cope with your everyday life pain-free?

The answer significantly influences the operational planning.

What is your bone quality?

A stable bone opens up different possibilities than a severely osteoporotic bone.

That's another reason why good endoprosthetics begins long before the first skin incision.

What does your individual anatomy look like?

No two femurs are exactly alike.

There are major differences regarding

• Form,
• Curvature,
• Market space
• Offset,
• Femoral neck geometry
• and bone quality.

These anatomical differences play a crucial role in implant selection.

Why bone preservation plays a major role today

Modern endoprosthetics increasingly pursues the goal of

To preserve as much healthy bone as possible.

Why?

Very easy.

Your own bones are always biologically valuable.

The more healthy bone structure is preserved,

The more cost-effectively burdens can be transferred.

Furthermore, better conditions are often available in the event of a later revision surgery.

This idea is becoming increasingly important, especially for younger and more active patients.

Short shaft or standard shaft

A frequently asked question

Many patients read on the internet,

that short-stem prostheses are particularly modern.

Others hear

that standard shafts are more proven.

What is correct?

The answer is:

Both can be correct.

It depends on,

for which patient.

Short stem prostheses can offer many advantages – provided the anatomy is suitable and the surgeon has the appropriate experience.

They often allow for bone-sparing joint replacement and are more closely aligned with the individual anatomy of the patient.

Standard shafts, in turn, also deliver excellent long-term results and remain the right choice in numerous situations.

Therefore, the crucial question is not:

Short shaft or standard shaft

Rather:

Which solution best suits my individual situation?

Modern short-stem prostheses – more than just a shorter stem

A common misconception is to view short-stem prostheses simply as "miniaturized standard stems".

In fact, modern short-shaft systems follow their own philosophy.

Provided the anatomical conditions are met, they should – as far as possible – preserve the natural bone and reconstruct the individual biomechanics of the hip joint in the best possible way.

The goal is not to use as little metal as possible.

The aim is to make the stress on the bone as physiological as possible and to restore the patient's natural anatomy as best as possible.

What role does surgical technique play?

Even the best prosthesis can only realize its full potential if..

when it is implanted precisely.

This includes, among other things,

• the exact positioning of the hip socket,
• the correct reconstruction of leg length,
• the restoration of the offset,
• the correct rotation position,
• as well as the gentlest possible treatment of muscles and soft tissues.

Therefore, the choice of clinic should never be based solely on the implant name.

The surgeon's experience and careful surgical planning are at least as important.

What patients often underestimate

Many people are intensely preoccupied with the question,

which prosthesis will be implanted.

They ask significantly less often,

how their muscles are rebuilt after the operation.

The subsequent function depends at least as much on the rehabilitation as on the implant itself.

A modern hip prosthesis only unfolds its full potential when..

when muscles,

Coordination,

Gait

and mobility are systematically trained.

For this reason, objective methods such as functional force measurements, EMG analyses and AI-supported gait analyses are becoming increasingly important today.

They help to not only assess the success of the treatment subjectively, but also to make it objectively measurable.

What can I expect after a hip or knee replacement?

The path back to an active life

For many people, the real uncertainty doesn't end with the decision to have surgery.

On the contrary.

Only then do new questions arise.

Can I walk normally again after the operation?

How long will I need walking aids?

When am I allowed to drive a car?

When can I go back to work?

When can I travel again?

Will I be able to go hiking, play golf, or cycle again later?

These questions concern most patients far more than technical details about implants.

The good news is:

Modern hip and knee replacement surgery means far more than just a successful operation.

It means giving you back your mobility and quality of life, step by step.

The operation is not the goal

Many patients initially think:

"Once the operation is complete, it's all over."

In fact, the operation marks the beginning of a new chapter.

Because the actual success of the treatment arises from the interplay of:

• a careful surgical plan,
• a precise implantation,
• early mobilization,
• a structured rehabilitation
• and your own active participation.

The operation creates the necessary conditions.

Rehabilitation turns it into a functioning joint.

Getting up again on the day of the operation

One of the biggest surprises for many patients:

After a modern hip or knee replacement, you no longer have to stay in bed for days.

Quite the opposite.

In most cases, mobilization begins just a few hours after the operation.

Together with experienced physiotherapists, you will stand up again for the first time, take your first steps and learn how to safely use your new joint.

For many patients, this is an emotional moment.

It is not uncommon to hear on this first day:

"The arthritis pain is gone."

Naturally, there will still be some pain from the wound, and the new joint needs time to heal. Nevertheless, many people experience a significant change immediately after the operation.

Why early movement is so important

Previously, it was believed that an operated joint should be protected for as long as possible.

Today we know:

Early, controlled movement is an essential component of successful rehabilitation.

She helps,

• to activate the muscles,
• to normalize the gait pattern
• to promote blood circulation
• to build confidence in the new joint
• and to reduce the risk of certain complications.

Therefore, movement is not seen as a burden, but as part of the treatment.

Rehabilitation today means more than just physiotherapy

Many people imagine rehabilitation as involving some exercises performed on a couch.

Modern endoprosthetics goes significantly further.

The goal is not simply to make the joint mobile.

The actual goal is:

To bring them back to their normal lives.

These include, among others:

• Muscle strength
• Balance,
• Coordination,
• Endurance,
• Gait pattern
• Movement quality,
• Everyday safety,
• and – if desired – a return to sports.

The goal is not just freedom from pain

Naturally, almost all patients wish to finally be pain-free again.

However, modern endoprosthetics pursues a significantly larger goal today.

It should enable you to

to go for spontaneous walks again

climbing stairs without thinking,

playing on the floor with your grandchildren,

to enjoy holiday travel,

to ride a bike again

playing golf

to go hiking

or simply to get up in the morning without pain.

In other words:

The focus is not on the prosthesis.

Their lives are the focus.

Why objective performance monitoring is becoming increasingly important

Previously, the success of a hip or knee replacement was primarily assessed using an X-ray image.

Today we know that a beautiful X-ray image alone says little about how well a patient actually moves.

Therefore, objective functional analyses are becoming increasingly important.

Examples include:

• standardized force measurements,
• functional movement analyses,
• Gait analysis,
• Measurements of muscle activity (EMG),
• as well as modern AI-supported methods for analyzing the movement sequence.

These examinations help to make progress visible and to tailor the rehabilitation specifically to your needs.

Not every patient needs all of these procedures. However, they demonstrate how endoprosthetics is increasingly evolving from a purely implant-oriented discipline to a functionally oriented medicine.

When can I start exercising again?

This is one of the most frequently asked questions.

The answer depends on several factors, including:

• the type of operation,
• Your general state of health,
• Your training level before the operation,
• the healing,
• and the respective sport.

Many activities are possible again after successful rehabilitation.

These often include:

• Hike,
• Ride a bike,
• To swim,
• Golf,
• Nordic Walking
• Fitness training,
• Dance,
• Cross-country skiing.

Even more demanding sports may be possible again in selected cases. However, the appropriate level of exertion should always be discussed individually with the treating surgeon.

Patience is part of rehabilitation

Many patients want to be able to do everything again as quickly as possible.

That's understandable.

Nevertheless, the body needs time.

Muscles need to be built up.

Tendons and soft tissues heal.

The nervous system learns new movement patterns.

Trust is built step by step.

A successful rehabilitation is therefore not a race.

It is a planned process.

Giving your body this time often creates the best conditions for a long-term successful result.

My personal experience

After many years in endoprosthetics, I have learned:

The happiest patients are rarely those with the most beautiful X-ray image.

These are the ones who

who are playing with their grandchildren again,

enjoy their first pain-free vacation,

hiking again for the first time in years,

or be able to say again after a long time:

"I don't even think about my hip anymore."

That, for me, is the real success of a hip or knee replacement.

Which knee prosthesis is right for me?

Why not every knee prosthesis is suitable for every person

When patients learn that they may need an artificial knee joint, one of the first questions is usually:

"Which knee prosthesis is actually the best?"

Similar to the hip issue, there is no universally valid answer to this.

Because modern knee replacement surgery no longer means inserting the same prosthesis into every patient.

Rather, the aim is to adapt the treatment as precisely as possible to the individual situation.

Numerous factors play a role:

• Which areas of the knee joint are worn?
• How stable are the straps?
• How severe is the misalignment?
• How active would you like to be after the operation?
• What are your expectations for your new joint?
• What accompanying illnesses are present?

Only once these questions have been answered can a decision be made as to which implant might be suitable for you.

The knee is more complex than many people realize

While the hip joint, to put it simply, resembles a ball-and-socket joint, the knee is one of the most complex joints in the human body.

With every step, the knee glides, rolls, and rotates simultaneously.

Muscles, ligaments, menisci and cartilage work together in a finely tuned interplay.

Therefore, modern knee arthroplasty does not aim to replace as much as possible.

Its goal is to

to replace as much as necessary and as little as possible.

Does the entire knee always have to be replaced?

Many patients initially assume that in cases of osteoarthritis, the entire knee joint must be replaced.

However, that is not true.

In many cases, cartilage wear is limited to a specific area of ​​the knee joint.

Then, under certain conditions, a partial denture can be an excellent solution.

However, whether a partial denture is an option depends on various factors and must be assessed individually.

The partial prosthesis

If only part of the knee joint is affected

In many patients, osteoarthritis is initially limited to the inside of the knee joint.

If the remaining articular cartilage is well preserved and, in particular, the cruciate ligaments are sufficiently functional, a partial prosthesis may be a suitable option.

Only the worn part of the joint is replaced.

Healthy bone and cartilage components are preserved.

The natural ligament alignment of the knee also remains largely intact.

Many patients later perceive the knee as feeling particularly natural as a result.

What advantages can a partial denture offer?

Under suitable conditions, a partial denture can have the following advantages, among others:

• less bone loss,
• Preservation of large parts of the natural knee joint,
• smaller implants,
• often faster functional recovery,
• often a more natural feeling of movement
• Good options for future revision surgeries, should these become necessary at some point.

However, these benefits only apply if the conditions are actually met.

A partial denture is not a "small full denture", but an independent treatment concept with clearly defined indications.

When is a full denture advisable?

If the osteoarthritis has already spread to several joint sections or if there are additional changes, a partial prosthesis is often no longer sufficient.

In many cases, a modern total knee replacement offers the best opportunity to permanently relieve pain and restore joint function.

However, even here there is no single "one" complete knee replacement.

Depending on the situation, different implant designs and stability concepts may be suitable.

The goal is always to create a stable, mobile and resilient knee joint that suits your individual requirements.

The right size is crucial

A knee replacement is not simply a standard implant.

It must be adapted as precisely as possible to the patient's anatomy.

Among other things, the following play a role:

• Size of the femur,
• Size of the tibial plateau,
• Band tension
• leg axis
• Rotation position,
• Joint line height,
• as well as the position of the kneecap.

Even slight deviations can affect the later feeling of movement.

Therefore, high-quality knee replacement surgery begins with careful pre-operative planning.

The operation does not end with the skin sutures

Many patients understandably focus on the implant.

In fact, the time after the operation often determines how good the new knee will feel later.

Especially after a knee replacement, consistent physiotherapy, muscle building and gait training are of great importance.

Only when muscles, coordination and mobility are systematically trained can the new joint reach its full potential.

Therefore, modern endoprosthetics centers do not view rehabilitation as an add-on to the operation, but as an integral part of the treatment concept.

The most important message

If you only want to remember one thought from this chapter, let it be this:

Not every case of knee osteoarthritis requires the same prosthesis.

The best knee prosthesis is the one that best suits your knee, your anatomy, and your personal goals.

Therefore, the decision should never be made solely on the basis of an X-ray image or an implant name.

It should be the result of a careful examination, individual planning, and a detailed discussion with an experienced specialist.

What does rehabilitation after a hip or knee replacement entail?

Why rehabilitation is at least as important as surgery

Understandably, many patients focus primarily on the surgery before undergoing a hip or knee replacement.

They ask themselves:

How extensive will the procedure be?

Which prosthesis will I receive?

How long will I have to stay in the hospital?

Long-term success is often only determined in the weeks and months following the operation.

A perfectly implanted prosthesis alone does not guarantee a perfect result.

Only the interplay of surgery, consistent rehabilitation and your own active participation leads to an artificial joint becoming a natural movement pattern again.

That is precisely why, in the modern fast-track concept, rehabilitation does not begin only after discharge from the clinic.

It begins immediately after the operation.

The first hours after the operation

Just a few decades ago, patients often had to stay in bed for several days after a hip or knee replacement.

Today we know that early mobilization offers many advantages.

Just a few hours after the procedure, most patients – naturally under the guidance of experienced physiotherapists – are able to stand up again for the first time.

The first steps often feel unfamiliar.

However, many patients report a surprising experience on that very day:

The pain from osteoarthritis has disappeared.

Naturally, there is still some pain immediately after the operation, and the tissue needs time to heal. Nevertheless, many people experience a significant reduction in debilitating joint pain immediately after the procedure.

These first steps often mark the beginning of a new phase of life.

Rehabilitation is far more than physiotherapy

Many people associate rehabilitation solely with a few physiotherapy exercises.

However, modern endoprosthetics takes a significantly more comprehensive approach.

The goal is not simply to make the new joint mobile.

Our goal is to return you to your everyday life safely, resiliently and as naturally as possible.

These include, among others:

• Restoration of mobility
• Muscle development
• Improvement of strength and endurance
• Balance and coordination training
• Optimization of gait pattern
• Everyday safety
• Preparation for career, leisure and sports

Each of these components contributes to ensuring that you can make optimal use of your new joint in the long term.

Rehabilitation at the ENDOPROTHETICUM Rhein-Main

At ENDOPROTHETICUM Rhein-Main, our care does not end with the operation.

On the contrary.

We understand rehabilitation as an integral part of our overall treatment concept.

Our goal is to continuously support you on your journey back to an active everyday life.

Through close collaboration between surgeon, physiotherapist and the ENDOPROtherapeuticum, therapy recommendations can be individually tailored to your healing process.

Instead of viewing surgery and aftercare as separate phases, we pursue an integrated concept with short pathways and close professional exchange.

In our experience, this close integration contributes significantly to a structured and safe rehabilitation.

Modern functional diagnostics – because an X-ray image alone doesn't show everything

An X-ray image can perfectly show whether a prosthesis is correctly positioned.

However, it does not answer all questions.

How well do your muscles work?

How steady are your steps?

Are you putting weight on both legs symmetrically?

What movement patterns may have crept in over the years?

Therefore, functional studies are becoming increasingly important.

At ENDOPROTHETICUM Rhein-Main, we use modern methods – depending on the question – to objectively assess the functional healing process.

Examples include:

• functional strength tests,
• Motion analysis,
• EMG-based muscle analysis,
• as well as AI-supported markerless gait analysis.

These tests do not replace a medical examination or a personal consultation.

However, they can help to identify deficits early and to tailor rehabilitation even more specifically to your individual needs.

Our goal is not just to make your prosthesis look good on the X-ray.

Our goal is for you to move around safely, naturally and with joy in your everyday life.

How long does the rehabilitation take?

This question cannot be answered in general terms.

Everyone heals differently.

Age, general health, muscle strength, comorbidities and physical activity before surgery influence the healing process.

Many patients reach important milestones within the first few weeks.

However, the complete functional adaptation of the body to the new joint is a process that can develop over several months.

Therefore, it is worthwhile to be patient and to consistently continue the rehabilitation.

Every day of training is an investment in the long-term function of your new joint.

When can I start exercising again?

We hear this question almost every day.

The answer depends, among other things, on your individual starting situation, the healing process and the chosen sport.

Many activities such as cycling, swimming, hiking or golf are often possible again after successful rehabilitation.

We will discuss with you individually which sports are suitable for your personal situation.

Our goal is not to impose as many prohibitions on you as possible.

Our goal is to safely and sustainably guide you back to an active life.

Our philosophy

For us, a successful hip or knee replacement does not end with the last stitch.

It only ends when you hardly notice your new joint in everyday life.

When you spontaneously go for a walk again.

When you travel again.

When you play with your grandchildren again.

When you return to your hobby.

And when you get up in the morning without having to think about your hip or knee joint first.

This is precisely where we see the real success of modern endoprosthetics.

Because our goal is not just a successful operation.

Our goal is your return to an active, self-determined and, if possible, pain-free life.
