How do I best prepare for an endoprosthesis (hip replacement, knee replacement)?
Why is preparation (prehabilitation) for an artificial joint so important?

Deciding to have an
endoprosthesis – an artificial joint – is a major step. Whether it's
a hip replacement
(total hip arthroplasty) or
a knee replacement (total knee arthroplasty) , thorough
preparation is crucial for the success of the surgery, the speed of recovery, and the longevity of the implant.
This article explains in detail
how you can best prepare yourself physically, mentally, and logistically for your endoprosthesis, what
prehabilitation means, the
nutrition,
exercise,
medication , and
psychological factors – and why it's worthwhile
ENDOPROTHETICUM Rhein-Main to have the treatment performed
Many patients underestimate how much their own body and mind can influence the success of surgery. Well-planned
preparation for a hip or knee replacement shortens rehabilitation, reduces pain, and lowers the risk of complications.
Measurable benefits can be achieved through targeted measures even just a few weeks before the operation.
- Better muscle strength and mobility
- Stabilized circulation and metabolism
- Fewer inflammations and infections
- Faster mobilization after surgery
In this context, modern medicine speaks of "prehabilitation" – that is, targeted training and optimization of the state of health before an operation.
What does prehabilitation mean for hip TEP or knee TEP?
Definition and objective
Prehabilitation is the counterpart to traditional rehabilitation. While rehabilitation takes place after surgery, prehabilitation
before the procedure optimally prepares the body and mind for the upcoming stresses
The goal is to strengthen muscles, the cardiovascular system, lungs, and metabolism so that the body
endoprosthesis regenerates more quickly
Patients who participate in a structured prehabilitation program have in studies:
- a shorter hospital stay,
- lower pain levels,
- fewer postoperative complications
and faster recovery of mobility.
How long should one prepare?
Ideally, preparation begins
4–6 weeks before the planned surgery. During this time, muscles, circulation, nutrition, and mental well-being can be specifically strengthened.
However, even if the date is set at short notice, it is worthwhile to become active even a few days before the operation – every step counts.
Physical preparation for an endoprosthesis
Muscle building and joint mobility
Strong muscles around the affected joint are the most important factor for a smooth healing process. This is especially true for hip replacements (total hip arthroplasty) and knee replacements (total knee arthroplasty): the stronger the surrounding muscles, the better the new joint is guided and stabilized.
Recommended exercises (after consultation with a doctor or physiotherapist):
- Leg axis training: Activation of quadriceps and hip abductors
- Balance training: Improvement of coordination
- Stretching exercises: Maintaining flexibility and preventing muscle shortening
- Breathing exercises: Strengthening the diaphragm for better oxygen supply
Many specialized clinics already offer prehabilitation programs that are individually tailored to the respective endoprosthesis.
Weight and Metabolism
Excess weight increases the risk of
complications, impaired wound healing, and loosening of the prosthesis.
Therefore, it is recommended to achieve a stable, healthy weight before surgery. Even a
5–10% weight reduction can significantly reduce joint stress.
Patients with diabetes, high blood pressure, or metabolic disorders also benefit from medically supervised adjustments to their medication before the procedure.
Nutrition before surgery
A balanced diet rich in protein, vitamins, and minerals is essential for
wound healing and tissue regeneration.
The following are particularly important:
- Protein (fish, legumes, dairy products) for muscle building
- Vitamin C and zinc for the immune system
- Vitamin D and calcium for bone quality
Patients should reduce their alcohol and nicotine consumption as much as possible, as both negatively affect blood flow and healing.
Medical preparation and preliminary examinations
Preoperative diagnostics
Before any endoprosthesis is implanted, a series of medical examinations are conducted to minimize risk and optimally plan the procedure.
These include:
- Blood test (inflammation markers, coagulation, electrolytes)
- ECG and if necessary lung function test
- X-ray or MRI for precise surgical planning
- Investigation of chronic diseases such as diabetes or heart problems
An experienced endoprosthetics specialist coordinates these investigations and matches all results with the planned operation.
Medication management
Many medications need to be adjusted before surgery, especially:
- Blood thinners (e.g. ASS, Marcumar, NOACs)
- Diabetes medications
- Antihypertensive medications
- Corticosteroid-containing medications
These adjustments are always made in close consultation with the surgeon. The aim is to minimize the risk of bleeding while simultaneously ensuring a safe cardiovascular situation.
Vaccination status and infection prophylaxis
Complete
vaccination, especially against influenza, COVID-19, and pneumococcus, is recommended before joint replacement surgery.
Equally important:
- Check for dental and skin infections (even the smallest inflammations can be sources of bacteria).
- Treatment of chronic infections (e.g., sinuses).
Because: An infection in the body can lead to dangerous prosthesis infections .
Psychological preparation for an endoprosthesis
Mental strength and expectation
Joint replacement surgery triggers anxiety in many patients: pain, anesthesia, and limited mobility. These concerns are perfectly normal – but they can be actively addressed.
A
positive attitude and realistic expectations have been proven to improve postoperative outcomes.
Helpful measures:
- Conversations with the surgeon – the better the understanding, the less fear.
- Breathing and relaxation techniques – for stress reduction.
- Contact with former patients – to gain realistic insights into the process.
Educational conversation as an opportunity
The
consultation is far more than a mandatory event. It offers an opportunity
to openly address all questions – for example, about implant types, durability, anesthesia, pain management, or rehabilitation.
A specialist like
Prof. Dr. Karl Philipp Kutzner places great importance on ensuring that patients make their decision with conviction and confidence.
Preparing daily life and living environment for the endoprosthesis
Preparation
for a joint replacement doesn't end in the doctor's office or the training room – it begins at home.
An
optimized living environment is crucial for safe and independent mobility after the operation.
Avoid tripping hazards
After
hip
(total hip arthroplasty) or
knee replacement (total knee arthroplasty) , balance is often still impaired. Even small obstacles can lead to dangerous falls.
Therefore:
- Remove loose rugs, cables, and small furniture.
- Ensure good lighting – especially on the way to the bathroom or bedroom.
- Keep passageways clear to be able to pass comfortably with walking aids.
Patients often report that these simple measures greatly facilitate everyday life after surgery.
Organize daily assistance
Prepare your daily routine so that you as independent as possible after your joint replacement surgery . Helpful items include:
- Grabbers and long-handled shoehornsto avoid bending over.
- Elevated toilet seats and shower stoolsto protect the joint.
- Non-slip mats in the bathroom and shower.
- Comfortable shoes with a firm sole and Velcro closure instead of laces.
These adjustments ensure safety – especially in the first few weeks after a hip or knee replacement.
Household help and social support
Endoprosthesis surgery is physically and logistically demanding. Planning for support early on helps avoid stress.
- Ask relatives or friends to help with shopping or cooking.
- Inform your employer about the upcoming surgery and the expected downtime.
- Clarify the organization of rehabilitation – inpatient or outpatient.
A well-planned daily routine reduces anxiety and accelerates the return to a self-determined life.
Prehabilitation in detail - the training plan before the endoprosthesis
The basic idea of prehabilitation
Prehabilitation means preparing the body for upcoming stresses – with targeted training that improves strength, mobility, and endurance.
This concept is now an integral part of modern endoprosthesis centers, such as the
ENDOPROTHETICUM Rhein-Main, where individually tailored programs are developed.
Training focuses for hip replacement (Hip TEP)
Patients who receive a hip replacement benefit from exercises that strengthen the surrounding muscles:
- Hip abductor training (lateral leg raises)
- Pelvic tilts while lying down to activate the deep trunk muscles
- Mini squats to improve standing stability
- Single-leg standing exercises to improve balance
It is important that the exercises painlessly are performed
Training focuses for knee prosthesis (Knee-TEP)
For patients with a planned knee replacement , the focus is on:
- Quadriceps strengthening (e.g., leg extensions while seated)
- Leg axis control to stabilize movement
- Mobilization of the kneecap to improve mobility
- Stretching of the back of the thigh (Ischiocrural musculature)
Many affected individuals benefit from physiotherapeutic guidance to avoid poor posture and overloading.
Breathing and cardiovascular training
A well-trained cardiovascular system improves oxygen supply and wound healing.
Recommended activities:
- Daily walks (10–30 minutes)
- Ergometer training without load peaks
- Breathing exercises for lung ventilation
These measures reduce the risk of thrombosis, infections, and circulatory problems after surgery.
Nutrition and nutrient supply before endoprosthesis
The importance of a protein-rich diet
Protein is the building block for muscles, skin, and connective tissue. Adequate intake is crucial before surgery to prevent muscle atrophy. A
is recommended
of 1.2–1.5 g of protein per kilogram of body weight – ideally from lean meat, fish, eggs, legumes, or dairy products.
Those who have difficulty consuming enough protein can use medically recommended protein drinks or shakes .
Vitamins and trace elements
simple
Vitamin D,
zinc,
vitamin C , and
iron play
wound healing a crucial role
blood test before surgery can detect any deficiencies. If a deficiency is found, it can usually be corrected within a few weeks – often through a combination of diet and supplements.
Hydration and metabolic balance
Adequate fluid intake (1.5–2 liters daily) stabilizes circulation, blood pressure, and metabolism.
Older patients, in particular, often forget to drink regularly.
are ideal
Water, unsweetened teas, or diluted fruit juices. Caffeine and alcohol should be reduced in the weeks leading up to surgery to avoid putting additional strain on the body.
Mental and emotional preparation
Understand anxiety – and reduce it specifically
Many people associate
joint replacement surgery (artificial joint replacement) with fear of pain or loss of control. However, modern medicine and specialized clinics now offer a virtually pain-free experience.
Open communication with the surgeon or anesthesiologist helps to alleviate concerns.
Mental preparation can include:
- Breathing techniques or meditation for stress reduction
- Daily relaxation timeto promote sleep and regeneration
- Positive visualization: Imagining being able to walk or run again without pain
A stable psyche demonstrably promotes healing.
Developing realistic expectations
Even with the best
hip or knee replacement, the body needs time to adapt.
The goal is
freedom from pain and mobility, not necessarily high-performance sports.
Patients who understand this experience their recovery more positively and with greater motivation.
The treating physician should transparently discuss realistic goals – e.g., when stair climbing will be possible again or when driving will be allowed.
The day before surgery
Final Preparations
The day before surgery is for rest. Plan everything essential:
- your documents, medication, and insurance card ready.
- Leave valuables at home.
- Final personal hygiene and disinfection shower as per doctor's instructions.
- A light meal in the evening and plenty of fluids.
Psychologically helpful: A short walk to build trust in your own body.
The day of surgery itself
On the day of your surgery, it's important
to stay calm. The medical team will ensure your safety and comfort.
Before the anesthesia, all steps will be explained again. The procedure then begins – the implantation of a
hip or knee replacement (total hip replacement, total knee replacement) usually only takes about one hour.
After the recovery phase, pain therapy and initial mobilization follow. Modern concepts ("fast-track endoprosthetics") make it possible to be back on your feet just a few hours after the operation.
After the operation: The first days with endoprosthesis
Early mobilization and first steps
On the day of the procedure, Professor Kutzner and the nursing team will assist you in getting up.
The goal is
to quickly activate your circulation, muscles, and joint function.
Early movement significantly reduces the risk of thrombosis, infection, and muscle atrophy.
Pain management
Modern pain therapy now uses multi-stage procedures:
- Local nerve blocks
- Combination drug therapy
- Cold and relaxation techniques
The goal is not complete freedom from pain, but a controllable, functional statethat allows movement.
Rehabilitation after endoprosthesis - the way back to movement
The actual surgery is only the beginning. The long-term success of an endoprosthesis depends crucially on rehabilitation . It is the key to mobility, quality of life, and the longevity of the implant.
Early phase - the first weeks
The first few days after surgery are characterized by gentle mobilization. The goal is to build confidence in the new joint.
physiotherapist
. The first mobilization takes place on the first or second day after the operation, under the guidance of a
Early phase goals:
- Restoration of balance
- Activation of the Musculature
- Improvement of joint mobility
- Pain reduction through movement
This requires patience and consistency - every movement, every getting up counts.
The rehabilitation forms
Hospitalization is usually followed by inpatient or outpatient rehabilitation. Both options have advantages and disadvantages that should be decided on an individual basis.
- Inpatient rehabilitation:
Patients live in a rehabilitation clinic for 2–3 weeks, where therapy sessions take place daily. Ideal for elderly people or those living alone. - Outpatient rehabilitation:
Patients sleep at home and attend a specialized facility during the day. Particularly suitable for younger, mobile people with family support.
ENDOPROTHETICUM Rhein-Main supports its patients in choosing the optimal form of rehabilitation – with ENDOPROtherapeuticum, follow-up treatment in the form of ENDO-Reha is also available in Mainz.
Rebuilding phase – targeted muscle training
In the following weeks, the focus will shift
strength and coordination training .
Targeted exercises will help to stabilize the joint and normalize its function.
Recommended focuses:
- Muscle building (thighs, buttocks, torso)
- Gait training with and without walking aids
- Exercise in water (aquagymnastics)
- Stretching exercisesto keep the joint capsule supple
Many patients experience pain-free movement for the first time in this phase – a motivating experience that accelerates the healing process.
Long-term care of the endoprosthesis
Regular aftercare
An
endoprosthesis is a high-tech medical device – and should be monitored accordingly.
Regular follow-up examinations with a specialist can be crucial to:
- the fit and stability of the prosthesis to check
- wear and tear or loosening to detect
- and adjust the individual exercise program as needed.
Long-term exercise recommendations
A
hip or knee replacement is not an obstacle to activity – quite the opposite.
Regular exercise keeps muscles, bones and the circulatory system healthy.
Recommended sports:
- Cycling (ergometer and outdoors)
- Nordic walking
- Swimming and aqua jogging
- Leisurely walking or golf
are less recommended jumping, stopping or turning movements, such as tennis, football or jogging on hard surfaces,
Nutrition and weight control after surgery
Even after successful implantation, body weight remains a crucial factor.
Every extra kilogram increases the pressure on the implant. A balanced diet therefore protects not only your heart and circulatory system, but also your prosthesis.
Recommended:
- Protein-rich, high-fiber diet
- Avoidance of highly processed foods
- Regular fluid intake
- Conscious control of body weight
Common mistakes in preparing for an endoprosthesis
Error 1: Too late activation
Many patients only start exercising shortly before their surgery. However, the earlier you start, the better.
Even simple exercises several weeks before the procedure can significantly improve the outcome.
Error 2: Fear-induced immobility
Avoiding all movement out of fear of pain weakens the muscles and impairs blood circulation.
Excessive rest before surgery significantly prolongs the rehabilitation phase afterward.
Error 3: Unbalanced diet
A one-sided or low-calorie diet can worsen wound healing. Particularly important is adequate protein intake – without it, the body regenerates more slowly.
Error 4: Unclear medication coordination
Stopping blood thinners, diabetes medication, or blood pressure medication on your own can be risky.
All changes must be discussed with your doctor to avoid complications.
Error 5: Lack of mental preparation
Many underestimate the importance of mental stability.
Fear, insecurity, and negative expectations can significantly impact the healing process.
Talking, visualization, and relaxation help build confidence in one's own strength.
Tips for relatives - how you can support
Good preparation not only concerns the patient but also the environment. Relatives can contribute decisively to success.
Practical tips:
- Encourage movement - but without pressure.
- Ensure a safe environment at home.
- Accompany them to doctor's appointments or rehabilitation.
- Offer emotional support and patience.
A positive, supportive atmosphere is the most important motivational factor for many affected individuals.
The role of specialized endoprosthesis centers
Why specialization is crucial
Not every clinic has the same experience in endoprosthetics. Studies show that
specialized centers with a high volume of cases and standardized procedures achieve better results, fewer complications, and higher patient satisfaction.
