Life with a hip replacement: 25 questions patients ask after surgery
Why has groin pain appeared? Can I have an MRI? How can dislocation or implant loosening be recognised? How long will the artificial joint last?
After hip replacement, patients gradually return to everyday life. Over time, however, new questions arise about more than the first steps after surgery: implant condition, investigations, possible restrictions and concerning symptoms.
We have collected another 25 questions patients frequently ask after hip replacement.

Why does my groin hurt?
Groin pain may be related to tissue healing, overloading of muscles and tendons, or irritation of the iliopsoas muscle. Early after surgery, these sensations often occur when lifting the leg, rising from a chair or walking.
If pain does not decrease, becomes worse or develops long after surgery, see an orthopaedic specialist. The cause is established through examination and investigations.
Why has thigh pain developed?
Discomfort in the upper or middle thigh sometimes occurs as the leg adapts to loading and tissues recover around the femoral component. It may be particularly noticeable when starting to move.
Increasing or persistent pain that interferes with weight-bearing requires assessment. The doctor may order an X-ray to check implant position and the surrounding bone.
What causes buttock pain?
Buttock pain does not always originate directly from the artificial joint. Muscle strain, changes in walking, lumbar spine problems or the sacroiliac joint may be responsible.
The location alone cannot identify the source. If pain persists or radiates down the back of the leg, an in-person assessment is advisable.
Why am I still limping?
A limp may be related to weak gluteal muscles, a habit of protecting the previously painful leg, impaired balance or a difference in leg length. It can take time to change a walking pattern established before surgery.
If the limp does not improve or becomes more pronounced, muscle strength, pelvic position and implant condition should be checked.
Why does the implant click?
Occasional painless clicks may occur as tendons and soft tissues move near the joint. A sound alone does not necessarily indicate implant damage.
If clicking is accompanied by pain, a feeling of displacement, instability or restricted movement, see an orthopaedic specialist. Do not keep repeating a painful movement to provoke the sound.
How can I recognise a dislocation?
A dislocation usually causes sudden severe pain. The person cannot move the leg normally or bear weight, and the limb may appear rotated or lie in an unusual position.
This requires urgent medical attention. Do not try to straighten the leg or put the implant back into place yourself.
What signs may suggest implant loosening?
Possible signs include gradually increasing pain with weight-bearing, pain when beginning to walk, reduced stability and deterioration of joint function that had previously recovered.
Symptoms alone cannot establish the diagnosis. Loosening is assessed through examination and imaging, which the doctor compares with previous results.
Can the body reject the implant?
A joint implant is not rejected in the way a transplanted organ can be. Modern implant materials are designed to remain in the body for a long time.
When patients say “rejection”, they often mean infection, component loosening or a rare reaction to materials. Pain and other symptoms require investigation to establish the cause.
How long does the implant last?
A modern hip replacement may function for 15–20 years or longer. Longevity depends on age, body weight, loading, bone quality, implant design and the accuracy of placement.
Elapsed time alone is not an indication for another operation. A stable implant that causes no problems does not need preventive replacement.
When does an implant need replacing?
Another operation may be needed for component loosening or wear, recurrent dislocations, deep infection or a fracture of the bone near the implant.
The decision is not based on an image alone. The doctor considers symptoms, joint function, investigation findings and changes over time.
Can I have an MRI?
In most cases, a modern hip implant does not prevent MRI. Before the examination, tell both the doctor and the imaging staff about the implant.
Metal components may reduce image quality near the joint. Special MRI sequences or another diagnostic method may therefore be used.
Do I need regular X-rays?
Follow-up images allow component position to be assessed and changes detected before they cause marked symptoms. The operating surgeon sets the follow-up schedule.
If new pain, instability or worsening walking develops, do not wait for the scheduled appointment: seek medical advice earlier.
Why do I need an implant identification card?
The card records the manufacturer, model, sizes and other characteristics of the implanted components. This information may be needed for follow-up, investigations or another operation.
Keep the document with your other medical records. Having a photograph of it on your phone is also useful.
What materials is the implant made from?
Titanium and cobalt-chromium alloys, medical-grade ceramics and high-strength polyethylene may be used. Different components of one implant are usually made from different materials.
The combination is chosen according to anatomy, bone quality, age and the individual clinical situation.
What is a bearing couple?
A bearing couple is the pair of surfaces that contact each other as the artificial joint moves: the head and the liner. An example is a ceramic head against a polyethylene liner.
The material combination influences wear. The surgeon selects an appropriate bearing couple individually.
How does cemented fixation differ from cementless fixation?
With cemented fixation, components are secured using special bone cement. With cementless implants, a tight press-fit provides initial stability, and bone gradually grows onto the implant surface.
Both methods have been used for many years. The choice depends mainly on bone quality and the patient's individual circumstances.
What does “total hip replacement” mean?
Total hip replacement replaces both joint surfaces: the femoral head and the pelvic socket, or acetabulum. The implant usually includes a cup, liner, head and femoral stem.
This differs from a hemiarthroplasty, in which only the femoral side of the joint is replaced.
How much does the implant weigh?
There is no single weight: it depends on component size, model and materials. The implant weighs far less than the whole leg and is not usually felt as a separate heavy object.
Changes in body weight after surgery are more commonly related to swelling, reduced activity or other factors than to implant weight.
How long should I wear compression stockings?
Duration depends on blood clot risk, mobility, other medical conditions and prescribed medication to prevent clots.
There is no universal interval. Do not stop earlier than advised or extend use on your own; clarify the plan with your treating doctor.
When can I take a bath?
The surgical area may be immersed only after the wound has completely closed, with no drainage, unhealed areas or signs of inflammation.
Consider both wound healing and whether you can safely get into and out of the bath. Obtain the surgeon's permission before your first bath.
Can I run with a hip replacement?
Running places repeated impact loads on the implant and surrounding bone. Walking, swimming, cycling and other lower-impact activities are therefore usually recommended after hip replacement.
Occasional short runs are assessed individually. The decision depends on bone condition, implant stability, body weight and experience, so returning to running should be agreed with the surgeon.
When can I use a steam bath or sauna?
A steam bath or sauna should be avoided until the wound has healed completely. High temperatures may increase swelling, affect blood pressure and place additional demands on the cardiovascular system.
Resume heat-based activities after a follow-up examination and medical permission, starting with short sessions without extreme temperatures.
When can I swim?
Swimming is allowed after complete wound healing, provided the patient can safely enter and leave the water. Start gently, without sudden movements or prolonged exertion.
Some swimming strokes require substantial hip rotation. Discuss suitable movements with the doctor beforehand.
Can I drink alcohol?
Alcohol is incompatible with some pain medicines, antibiotics and other drugs. It can also increase the risk of falling and affect blood clotting.
While medication continues, discuss alcohol with your doctor. Moderation remains important after medicines have been stopped.
Can I wear high heels?
Early in recovery, stable footwear with non-slip soles and a low, broad heel is safer. High or narrow heels alter walking and increase the chance of losing balance.
You can return to familiar footwear after stable walking has recovered. If heels cause pain or make you feel unsteady, avoid them.
Living with a hip replacement does not mean constantly expecting complications. Most patients return to familiar activities and retain good mobility for many years.
New or increasing pain, sudden inability to bear weight, a feeling of displacement, wound drainage or noticeable deterioration in joint function require medical advice. Prompt assessment helps distinguish temporary discomfort from a problem that needs treatment.
