today hip replacement surgery , they quickly realize that medicine is undergoing a small revolution. Just a few decades ago, hip replacement was associated with extensive surgery, a long hospital stay, and frequent complications. Today, hip replacement is considered one of the most successful operations ever performed. Modern implants last for decades, and thanks to minimally invasive techniques , patients are often mobile again just a few days after surgery.

While these minimally invasive techniques have become the standard, an old concept is experiencing a surprising comeback: hip resurfacing. This procedure – often also a cap prosthesis – aims to preserve as much bone as possible. For a long time, however, this idea was burdened by serious complications, particularly metal abrasion.

Now, surface replacement is being discussed in a new form: no longer as a metal-on-metal prosthesis, but as a ceramic cap prosthesis. Ceramics have proven to be particularly wear-resistant and biocompatible in endoprosthetics. Could this be the solution to the problems of the past?

The crucial question, however, is: Can a ceramic surface replacement be implanted using minimally invasive techniques? For patients today, it is taken for granted that hip surgery should be performed through small, muscle-sparing incisions. This reveals a tension: The principle of surface replacement requires a completely different surgical technique, one that is hardly compatible with minimally invasive procedures.

In this article, we clarify:

• What exactly is hip resurfacing?
• Why was the technique discredited for so long?
• What does the new ceramic variant promise?
• What role do minimally invasive approaches play in modern hip surgery?
• Why are short stem prostheses the safe, bone-conserving and truly minimally invasive solution today?

Finally, you will learn why ceramic surface replacement sounds exciting but has significant disadvantages in practice – and where you Mainz / Rhine-Main a modern, minimally invasive hip prosthesis can get

2. What does hip resurfacing mean?

To understand why resurfacing is discussed so controversially, one must first understand the principle.

2.1 Definition: What is a Resurfacing Cap?

In classical hip replacement, the entire femoral head is removed. A prosthetic shaft is inserted into the femur, which is connected to a new femoral head ball. This ball then glides into an artificial acetabulum, which is implanted into the pelvis.

Surface replacement works differently:

• The natural femoral head remains largely preserved.
• Only the outermost layer of the bone is removed.
• is then metallic or ceramic cap placed over the femoral head and cemented or anchored.
• This cap forms the new joint surface with a corresponding acetabular cup.

In principle, it is a kind of "hip prosthesis-light" – the bone is largely preserved, and the anatomy of the thigh is hardly altered.

2.2 Objective: Maximum Bone Preservation

The most important advantage of surface replacement lies in bone preservation. This is particularly attractive for younger patients (under 55 years of age) who have a high life expectancy and may eventually require revision surgery.
The more bone that remains in the femur, the easier a subsequent prosthesis implantation will be.

2.3 Delineation from the classical hip prosthesis

• Standard hip prosthesis (straight stem): complete femoral head removed, long prosthetic stem anchored in the thigh.
• Short stem prosthesis: femoral head removed, but only a short stem anchored in the proximal femur → bone-saving, minimally invasive procedure possible.
• Surface replacement (cap prosthesis): The femoral head is preserved, only a cap is attached.

Thus, hip resurfacing positions itself between conservative joint preservation (e.g., osteotomy) and classical prosthesis.

2.4 Historical appeal

The idea of replacing a hip joint in such a way that the bone remains intact fascinated orthopedic surgeons since the 1970s. It corresponded to the desire of many patients:

• change as little as possible in one's own body,
• at the same time become pain-free and mobile again,
• and in the event of a revision, keep all options open.

However, as we will see in the following chapters, the reality of surface replacement had significant drawbacks for a long time.

3. History of Surface Replacement – From Hope to Disillusionment

3.1 First attempts in the 1970s

The idea of ​​not completely removing the femoral head, but only covering it with a prosthetic cap, originated in the 1970s. Early models of this so-called hip surface replacement were tested at that time using various materials.

The concept was equally attractive to patients and surgeons:

• Maximum bone preservation – especially valuable for young patients who will have to live with the prosthesis for many decades.
• More natural anatomy – by preserving the femoral neck, the original leverage and muscle attachments are largely maintained.
• Easier revision – if the prosthesis ever needs to be replaced, all options are open, as the bone in the thigh remains largely intact.

However, the first generations already had to struggle with significant problems: The anchoring of the caps was technically difficult, and the materials used at the time (e.g. Teflon or early metals) proved to be not very durable. Many implants loosened again after a few years.

3.2 The Renaissance in the 1990s and 2000s

After a rather disappointing start, surface replacement a comeback in the 1990s. This was mainly due to advances in metallurgy and prosthetic technology.

British orthopedic surgeons Derek McMinn and Ronald F. Treacy developed the well-known Birmingham Hip Resurfacing (BHR)system. It was hailed as a "game changer." Worldwide interest in the hip resurfacing prosthesis rapidly – ​​including in Germany.

Highlighted benefits:

• Young, active patients should remain physically active for longer.
• The natural movement sequence should be better preserved.
• Bone sparing should facilitate revisions.

Many clinics have adjusted their programs and offered hip resurfacing as a “modern alternative” to the classic hip replacement.

3.3 Metal-on-metal: The great hope

What was special about this generation of femoral head caps was the material: They used metal-on-metal bearing surfaces. This meant that both the cap on the femoral head and the socket in the pelvis were made of highly polished metal.

The hope was:

• Metal is supposed to be durable and resistant.
• The abrasion should be minimal.
• Large head sizes should reduce the risk of dislocation.

Initially, the results seemed promising. Thousands of patients worldwide received such metal prostheses in the early 2000s.

3.4 The problems became apparent quickly - metal wear

However, complications soon accumulated. After just a few years, the following problems became apparent:

1. Metal abrasion:
   With each step, the cap rubs against the pan. This creates tiny metal particles (cobalt, chromium, nickel) that can enter the body.
2. Metallosis:
   These metal particles accumulate in the surrounding tissue. This leads to inflammation, necrosis (tissue death), and pain.
3. Systemic metal ion exposure:
   Blood tests showed that patients with metal-on-metal caps had elevated cobalt and chromium levels in their blood. This can potentially damage organs – from the kidneys to the heart.
4. Premature loosening:
   Due to tissue damage, many prostheses loosened after only a few years. The originally planned lifespan of 15–20 years was far from being achieved.

3.5 Known scandals – the ASR example

became particularly notorious ASR system . This metal-on-metal system had to be recalled worldwide in 2010 after thousands of patients suffered serious complications.

The consequences:

• Numerous revision surgeries were necessary.
• There were global class-action lawsuits and billion-dollar compensation payments worldwide.
• The confidence in the surface replacement was massively shaken.

Other systems, such as the BHR prosthesis, also lost acceptance. National registries, e.g., in the UK and Australia, published alarming revision rates.

3.6 Withdrawal from routine

Following these experiences, many clinics decided to no longer routinely offer surface replacement. Professional societies such as the German Society for Orthopedics and Trauma (DGOU) and international institutions also warned against metal-on-metal systems.

Today it applies:

• is Metal-on-metal surface replacement now only used in exceptional cases.
• Most orthopedic centers have completely abandoned it.
• Patients who still have a metal cap prosthesis in their body are regularly monitored (including blood values for metal ions).

3.7 Lessons from the past

The history of surface replacement shows how great the discrepancy between theory and practice can be.

Theoretically:

• Bone preservation, natural anatomy, high mobility.

Practical:

• Metal wear, inflammation, loosening, systemic risks.

The most important lesson: An implant must not only be technically fascinating – it must also be safe in the long term.

This is precisely where the current discussion begins: If the problem was the material, could surface replacement with a new material – ceramic – be a real alternative?

3.8 Conclusion on the historical section

The surface replacement on the hip has a turbulent history:

• 1970s: first, largely unsuccessful attempts.
• 1990s/2000s: Boom due to metal-on-metal systems.
• From 2010 onwards: massive problems due to metal abrasion, recalls, loss of trust.
• Today: only a rare indication, but an exciting discussion about new materials.

Patients should be aware that the enthusiasm for surface replacement has always been based on the idea of preserving bone - a goal that remains highly relevant today. However, experience with metal-on-metal has shown how dangerous the wrong material choice can be.

4. The Innovation: Ceramic Resurfacing – the Comeback of the Cap Prosthesis?

4.1 Why ceramic?

Following the problems with metal-on-metal prostheses, research focused for a long time on safe, biocompatible materials. Ceramics have already proven themselves in endoprosthetics, particularly in hip sockets and conventional hip prostheses, as being extremely wear-resistant and biocompatible .

The benefits of ceramic at a glance:

• Biocompatibility: Ceramic does not react with the body, no systemic burden from metal ions.
• Low abrasion: Significantly less particle formation in the joint. The risk of metallosis is eliminated.
• Hardness: Ceramic is extremely hard and wear-resistant, which theoretically makes a long lifespan possible.
• Smooth sliding surfaces: Reduce the risk of joint noises or micro-movements that could lead to loosening.

For patients, this means that the cap prosthesis can theoretically from bone preservation without the risks of metal abrasion.

4.2 Structure and Functionality of the Ceramic Resurfacing Prosthesis

The ceramic cap prosthesis consists of several components:

Ceramic cap for the femoral head:

• Covers the preserved bone.
• Is cemented or press-fit fixed.

Acetabulum:

• Classic TEP socket made of ceramic or ceramic/polyethylene combination.
• Receives the cap and enables movement.

Fixation mechanism:

• Securing through bone compression or cement.
• Goal: immediate stability, no loosening.

In principle, the ceramic cap replaces the articular cartilage while preserving the natural bone. The joint's range of motion can remain very close to the original anatomy, and the stress on the femoral neck remains physiological.

4.3 Potential benefits for patients

1. Bone-sparing:
   Preserving the femoral neck is a significant advantage, especially for younger patients or those with higher activity levels. Should revision surgery become necessary at some point, more options are available.
2. No metal ions:
   Unlike metal-on-metal systems, the body is not exposed to metal ions – a crucial increase in safety.
3. Low abrasion:
   Ceramics produce less wear on sliding surfaces, which could reduce the loosening rate in the long term.
4. Large head size possible:
   As with metal cap prostheses, the femoral head can be chosen to be large → lower dislocation rate.

4.4 Challenges and risks

Despite the theoretical advantages, there are significant limitations:

Ceramic breakage:
While ceramics are hard and wear-resistant, they are also brittle. A break can have catastrophic consequences:

• Sudden instability of the joint
• Need for a complex revision surgery
• Potentially irreversible damage to the femoral head

Technical complexity of the operation:
In order to precisely place the cap on the femoral head, the joint must be dislocated. This means:

• Larger surgical approaches
• More soft tissue damage
• Longer rehabilitation time compared to minimally invasive short stem systems

Lack of long-term results:
While metal cap prostheses have data over 10–15 years, for ceramic cap prostheses only pilot studies or small cohorts so far.

• Long-term stability is still unclear
• Revisions on a larger scale are not sufficiently documented

Limited availability:
Ceramic cap prostheses are currently only offered in specialized centers and not as a standard part of routine operations.

4.5 Current clinical studies and research

In recent years, several research teams worldwide have pilot projects :

• Goal: Check load-bearing capacity, abrasion, dislocation risk and fracture resistance.
• First results:
• Low wear rate confirmed
• Dislocation rate low when implanted precisely
• Ceramic fractures very rare, but possible risk factors identified (e.g. mispositioning, suboptimal bone density)

The study authors concluded that ceramics are promising, but have not yet been widely clinically tested. Long-term data (10–15 years) are lacking.

4.6 Patient Perspective: Opportunities vs. Risks

For patients, the ceramic cap prosthesis initially sounds like the ideal solution:

• Bone remains preserved
• No metal wear
• Physiological mobility

But the reality is complex:

• surgery Minimally invasive possible
• Risk of ceramic fracture remains
• Long-term data are missing → uncertainty about durability and complications

Patients must weigh the options: Do they prefer an innovative but little-tested technique or a proven, safe alternative such as the short-stem prosthesis, which can be inserted minimally invasively and is demonstrably durable?

4.7 Conclusion Chapter 4

The ceramic cap prosthesis represents the logical next step in surface replacement: bone preservation without the risk of metal.

But:

• Minimally invasive implantation is hardly possible
• Ceramic fracture remains a theoretical but real risk
• Long-term results are missing

Patients should be aware of these risks and always make the decision in consultation with experienced hip specialists .

5. Minimally invasive hip surgery – the revolution of the last 10 years

Hip surgery has made enormous progress in recent decades. Besides innovations in materials, the focus has been primarily on minimally invasive surgical techniques . For patients, this means shorter hospital stays, less pain, faster mobilization, and less scarring.

5.1 What does "minimally invasive" mean?

The term "minimally invasive" describes surgical procedures that destroy as little tissue as possible while still allowing for safe implantation.

Features of minimally invasive hip surgeries:

• Small incisions (approx. 6–10 cm vs. 15–25 cm with traditional approaches)
• Muscle-sparing technique: Tendons, muscles, and ligaments are not cut, but pushed aside
• Preservation of the joint capsule, if possible
• Goal: faster recovery, less pain, shorter rehabilitation

These techniques are now at the center of modern hip surgery and have revolutionized patient care.

5.2 The established minimally invasive approaches

In the last 10 years, the following approaches have become established:

1. AMIS (Anterior Minimally Invasive Surgery / Direct Anterior Approach):

• Anterior approach, between muscles
• No cutting of important muscle groups
• Very low dislocation rate
• Rapid mobilization possible

1. Anterolateral approach (ALMIS):

• Muscle-sparing access from the front side
• Stable joint guidance, low risk of dislocation
• Proven for short-stem and standard prostheses

1. Posterolateral approach (PL):

• Posterior approach, slightly modified to preserve muscles
• Classic approach, can be adapted minimally invasively

5.3 Benefits for patients

Minimally invasive hip surgeries offer measurable benefits:

Less blood loss:

• Gentler muscle preparation → fewer intraoperative bleeding
• Less frequent transfusions necessary

Less postoperative pain:

• Muscles and tendons remain largely intact
• Reduced need for pain medication

Rapid mobilization:

• Patients often get up on the day of surgery or the first day after surgery
• Shortened hospital stays (2–5 days instead of 7–10)

Cosmetically advantageous:

• Small incisions → smaller scars
• Aesthetically pleasing, especially for younger patients

Better functional results:

• Muscle strength restored more quickly
• Daily life and sports possible more quickly

These advantages are clinically proven and make minimally invasive approaches a standard in modern orthopedic centers today.

5.4 Evidence and study situation

Numerous studies confirm the benefits of minimally invasive hip replacement implantations:

• Shorter hospital stays (reduction of 2–4 days)
• Lower pain score in the first weeks after surgery
• Faster return to normal activities
• Equivalent long-term results regarding implant loosening compared to traditional approaches

Conclusion: Minimally invasive procedures have no impact on long-term stability, but significantly improve postoperative quality of life .

5.5 Why hip resurfacing cannot really be implanted minimally invasively

Here lies the crucial difference:

• During surface replacement, the femoral head must be dislocated in order to precisely position the cap.
• This requires greater access and more soft tissue mobilization.
• Muscles and capsule are more heavily stressed → no minimally invasive approach possible.

Patient perspective:

• Despite modern material choices (ceramic), patients do not benefit from the minimally invasive advantages: higher pain, longer rehabilitation, larger scars.
• Minimally invasive surgery is a key feature of modern hip surgery, but it is technically difficult in surface replacement.

5.6 Summary Chapter 5

• Minimally invasive approaches are now standard in modern hip surgery.
• They enable faster recovery, less pain, and better functional results.
• The ceramic cap prosthesis cannot use these access pointsbecause dislocation of the femoral head is necessary.
• This is one of the biggest disadvantages of surface replacement compared to modern short-stem prostheses, which can be implanted minimally invasively.

6. Risks of the ceramic cap prosthesis

At first glance, the ceramic cap prosthesis seems like the ideal solution: bone preservation, biocompatible material, less wear. However, reality shows that even this modern option is associated with significant risks and uncertainties . Patients should be fully aware of these risks in order to make an informed decision.

6.1 Ceramic fracture – a rare but catastrophic risk

Although ceramics are extremely hard and wear-resistant, they have a brittle structure. This means:

• Under high stress, misalignment, or defects in the bone, the cap can suddenly break.
• A fracture leads to immediate instability of the joint.
• Affected patients require a complex revision surgery, often more involved than with classic short-stem prostheses.

Fact: Even if the probability of a fracture is low, the consequences are serious. Even minor cracks can lead to loosening or pain.

6.2 Soft tissue damage due to necessary luxation

To place the ceramic cap on the femoral head, the joint be dislocated. This means:

• Muscles, tendons, and capsule are stretched or mobilized more strongly.
• Minimally invasive access is not possiblebecause sufficient space is needed for the cap.
• Result: more postoperative pain, longer rehabilitation, higher risk of postoperative muscle weakness.

Patients need to understand: The operation itself is more invasive than a modern short-stem implantation, even though the material is actually innovative.

6.3 Lack of long-term results

While metal cap prostheses have 10–15 years of experience and registry data, only pilot studies or small cohorts exist for ceramic cap prostheses:

• Long-term stability over 15–20 years is unclear
• Revisions in the long-term course are hardly documented
• Data on physically active patients are missing

This means that the use remains experimental, even if initial results are promising.

6.4 Patient perspective

For young, active patients, the cap prosthesis sounds ideal:

• Bone remains preserved
• No metal wear
• Physiological joint mechanics

However, the disadvantages, such as the lack of minimally invasive access, ceramic breakage , and uncertain long-term results, must be clearly communicated. Patients who value rapid mobilization, short rehabilitation, and safe, proven solutions should explore alternative options.

Modern hip surgery offers proven solutions: e.g., the short stem prosthesis, which is bone-sparing and can be used minimally invasively.

6.5 Transition to modern alternatives

The short stem prosthesis combines the advantages of the cap prosthesis (bone preservation, high mobility) with the advantages of minimally invasive technique:

• Implantation via small, muscle-sparing approaches
• Proven long-term results
• Easier revision if needed

7. Short stem prosthesis as a modern alternative

The short-stem prosthesis has established itself in recent years as the preferred solution for many patients who require hip surgery but value bone preservation and minimally invasive techniques . It combines the advantages of surface replacement with the achievements of modern hip surgery – without the risks of ceramic resurfacing prostheses.

7.1 Structure and Functionality

The short-stem prosthesis differs from classic hip prostheses in that the stem is shortenedand inserted into the proximal part of the thigh:

Short prosthesis stem

• Anchored in the upper thigh bone
• Gentler on the bone, less material in the medullary cavity

Ball head and cup

• Standardized ceramic or polyethylene acetabular cup
• The ball head can be chosen large → low risk of dislocation

Fixation

• Press-fit or cemented, depending on bone quality
• Immediate stability guaranteed

Advantage over cap prosthesis:

• No risky ceramic cap fracture
• Minimally invasive implantation possible
• Long-term results proven

7.2 Minimally Invasive Implantation

The short stem prosthesis can be implanted via modern approaches :

• AMIS (Direct Anterior Approach): Muscles are spared; patients often stand up on the day of surgery.
• Anterolateral approach: Stable approach, low dislocation rate
• Posterolateral approach: Modified, muscle-sparing, proven

Patients benefit from these techniques:

• Less pain
• Faster mobilization
• Shorter hospital stay
• Smaller scars

Thus, the short stem prosthesis combines the advantages of the cap prosthesis (bone preservation) with those of minimally invasive hip surgery – a potential advantage over ceramic cap prostheses.

7.3 Evidence and long-term results

Registry data and clinical studies prove:

• Durability: Short stem prostheses have a long lifespan; revisions are easily possible.
• Stability: Low loosening rate, no increased dislocation rates
• Function: Muscle strength and mobility comparable to or better than with classic hip prostheses.
• Patient satisfaction: High, especially among active patients

Conclusion: The short stem prosthesis is not experimental, but proven and safe.

7.6 Short stem prosthesis vs. surface replacement

Brief comparison:

• Surface replacement (ceramic): High bone preservation, minimally invasive implantation impossible, risk of ceramic fracture, experimental
• Short stem prosthesis: good bone preservation, minimally invasive implantation possible, proven technique, easier revision

Conclusion: for most patients practical, safe and evidence-based alternative to surface replacement

For patients in the Mainz and Rhine-Main area, the ENDOPROTHETICUM under Prof. Dr. Karl Philipp Kutzner modern hip surgery with short-stem prostheses:

• Specialized in minimally invasive techniques
• Individual consultation and surgical planning
• High technical expertise, modern surgical technique, excellent aftercare

7.8 Conclusion Chapter 7

• The short-stem prosthesis combines bone preservation and minimally invasive implantation.
• Long-term results are proven, revisions are easier than with cap prostheses.
• Patients benefit from faster mobilization, less soft tissue damage and high security.
• For many young and active patients, it is the best choicewhen a hip replacement becomes necessary.

8. Surface replacement vs. short stem prosthesis – a direct comparison

The decision between surface replacement (especially ceramic resurfacing) and short-stem prosthesis is often not easy for patients. Both procedures aim to preserve bone and maintain functional hip movement , but differ considerably in safety, surgical approach, and long-term outcomes.

8.1 Bone preservation

Surface replacement:

• Goal: maximum preservation of the femoral head
• Advantage in future revision surgeries
• Risk: In case of complications or ceramic fracture, less intact bone remains

Short stem prosthesis:

• Bone preservation moderate to high, as only the proximal femoral portion is processed
• More options remain available for revisions
• Advantage: Combination of safety and bone preservation

Conclusion: Surface replacement is theoretically the maximum, short stem prosthesis is practical and safe.

8.2 Minimally invasive approaches

Surface replacement:

• Necessary luxation of the femoral head
• Greater soft tissue damage, potentially longer rehabilitation
• Minimally invasive implantation not possible

Short stem prosthesis:

• Implantation possible via muscle-sparing approaches (AMIS, ALMIS)
• Less soft tissue damage
• Rapid Mobilization

Conclusion: Minimally invasive advantages are only achievable with short-stem prostheses.

8.3 Material and safety

Ceramic surface replacement:

• Advantage: no metal abrasion, biocompatible
• Risk: Ceramic fracture with catastrophic consequences
• Long-term data missing

Short stem prosthesis (ceramic or polyethylene):

• Proven materials, low abrasion rate
• No brittleness, low risk of fracture or loosening
• Long-term data prove safety

Conclusion: Short-stem prostheses offer proven safety, surface replacement remains experimental.

8.4 Functional results

Surface replacement:

• Mobility close to the natural hip
• Risk of pain or limited function in case of complications

Short stem prosthesis:

• Mobility very good, comparable to surface replacement
• Muscles and tendons remain intact → faster daily life and sports

Conclusion: Functionally equivalent or better with short stem prostheses thanks to minimally invasive techniques.

Patient conclusion:
The short-stem prosthesis combines safety, bone preservation, and minimally invasive access. Surface replacement sounds attractive in theory, but is riskier in practice and hardly feasible using minimally invasive techniques.

• Ceramic surface replacement is an exciting but experimental process.
• Minimally invasive advantages are not feasible, ceramic fracture remains a residual risk, long-term results are lacking.
• Short stem prostheses offer proven safety, minimally invasive implantation and bone preservation.
• For patients rapid mobility, short rehabilitation, and long-term security , the short stem prosthesis is the more practical choice.

9. Summary

Deciding to have a hip replacement is a significant step for patients of all ages. Modern procedures offer bone preservation, rapid mobilization, and reliable long-term results, but not every procedure is equally suitable for every individual. This article has thoroughly examined the differences between ceramic resurfacing and short-stem hip replacements .

9.1 Key points at a glance

Ceramic surface replacement (capping prosthesis):

• Goal: maximum bone preservation and physiological joint movement
• Advantages: no metal wear, theoretically great mobility, bone-sparing
• Disadvantages:
• Dislocation of the femoral head necessary → no truly minimally invasive access
• Risk of ceramic fracture with serious consequences
• Long-term data missing, revisions complex
• Conclusion: Innovative, but experimental and with significant risks

Short stem prosthesis:

• Goal: Bone preservation combined with minimally invasive implantation
• Benefits:
• Minimally invasive possible via AMIS, anterolateral or posterolateral approach
• Proven materials (ceramic, polyethylene)
• Longer durability and safe long-term results (15–20 years)
• Easier revisions when needed
• Faster rehabilitation and lower postoperative pain
• Conclusion: Proven, safe and patient-friendly solution

9.2 Why minimally invasive is crucial

The last 10 years have shown that minimally invasive approaches are crucial for the success of hip surgery:

• Less soft tissue damage → less pain
• Faster mobilization → shorter hospital stays
• Better functional results → everyday life and sports possible faster

Patients who value rapid recovery, minimal pain, and functional safety particularly benefit from minimally invasive techniques – which are unfortunately not feasible in surface replacement.

9.3 Bone preservation vs. safety

Surface replacement sounds attractive because it maximum bone preservation . But practice shows:

• Risks such as ceramic fracture or lack of long-term experience relativize the advantage
• Minimally invasive implantation is not possible → longer rehabilitation, more pain

The short stem prosthesis, on the other hand, offers a balanced solution:

• Bone preservation is good to high
• Minimally invasive implantation
• Long-term results proven
• Revisions simpler and safer

For most patients, the short stem prosthesis is therefore the more practical and safer choice.

9.4 Decision-making aid for patients

If you are planning hip surgery, you should consider the following points:

Age and activity level:

• Young, active patients particularly benefit from bone-sparing and minimally invasive methods.

Material selection:

• Ceramic offers advantages, metal carries abrasion risks, ceramic cap prostheses are still experimental.

Surgical approach:

• Minimally invasive techniques reduce pain, scarring and rehabilitation time.

Long-term results and safety:
