Your recovery, step by step
Knee replacement recovery
A practical guide to Mr Mussa’s usual primary knee replacement pathway. Your written discharge instructions and the advice of your surgical and physiotherapy teams take priority.
This timeline is a guide, not a deadline. Recovery varies with your operation, health and progress. Revision surgery and complex procedures often need a different plan.
- Before surgery
Prepare for recovery
Use pre-assessment to review your health, medicines, practical support and home arrangements. Discuss any mobility concerns and the exercises your physiotherapist recommends before surgery.
- Day of surgery & hospital stay
Begin walking safely
The usual primary knee plan allows full weight-bearing with supervision. Nurses and physiotherapists will help you use walking aids. Same-day discharge or discharge within 24 hours may suit selected patients, but comfort, safety, mobility and the hospital’s discharge criteria determine when you go home.
- Weeks 0–2
Manage swelling and start movement
Work on both bending and fully straightening the knee using the exercises you are given. Take regular short walks and elevate the leg when resting as advised. Avoid sitting for long periods with the leg hanging down. Do not rest for prolonged periods with a pillow directly beneath the knee, as this can encourage it to remain bent.
- Around 14 days
Check the wound
Keep the dressing in place as directed and avoid unnecessary changes. If clips are used, the usual plan is removal by your practice nurse at around 14 days, unless the surgical team advises differently. Increasing redness, drainage, fever or worsening pain needs prompt review.
- Weeks 2–6
Build movement and confidence
Continue regular physiotherapy and gradually progress walking aids according to balance and gait. Contact your team early if bending or straightening is not progressing. A night splint is used only if prescribed for difficulty straightening the knee; it is not routine for everyone.
- Around 6 weeks & beyond
Review and progress
Mr Mussa’s usual review is at six weeks. Recovery continues over several months and swelling can settle gradually. Return to work, driving and sport depends on recovery and the demands of the activity. For a total knee replacement, NHS advice is to wait at least six weeks before driving and to check with your doctor that it is safe.
Getting active again
Exercise and sport after knee replacement
Regular activity helps rebuild movement, strength and confidence while the operated joint and surrounding tissues heal. Begin with the walking and exercises recommended by your physiotherapist and progress gradually.
Your discharge instructions take priority. This guide mainly concerns uncomplicated primary replacement. Revision surgery, custom reconstruction, fractures or additional repairs may require a different programme.
When can I return to exercise?
| Activity | What should guide your return? |
|---|---|
| Walking | Use your prescribed aids and increase distances as your walking pattern, strength and confidence improve. |
| Static cycling | Your physiotherapist can advise when your movement is sufficient and help with seat height and resistance. |
| Swimming | Wait until your wound has completely healed and your team agrees that you can enter, leave and use the pool appropriately. |
| Golf and low-impact gym exercise | Start with controlled, gentle practice before longer sessions or a full round. |
| Outdoor cycling and racquet sports | Discuss previous experience, balance, strength, twisting movements and fall risk with your team. |
British and American patient guidance generally favours lower-impact exercise after knee replacement. Some activities can be introduced during the early months, but fuller participation may take longer. These are guides, not clearance for every activity. Gentle practice and unrestricted participation are different stages.

Can I run after knee replacement?
Running and repeated high-impact exercise are generally not recommended after total knee replacement. Greater loads raise concerns about wear, loosening and injury, but the long-term risk for an individual runner is uncertain. It would be inaccurate to say every patient who runs will damage their replacement.
If running matters particularly to you, discuss your goals with Mr Mussa before surgery and before attempting to return. Your experience, operation, bone quality and recovery all matter. Reaching a particular month does not automatically make running advisable.

Can I play football, rugby or contact sports?
Contact and collision sports are generally discouraged because they involve impact, sudden changes of direction and possible falls. There is no standard postoperative date that makes them appropriate for everyone. Discuss your sport and level of participation with your surgeon; permission for gentle exercise does not mean clearance for competitive or contact sport.

Can I kneel after knee replacement?
Kneeling may remain uncomfortable because of scar sensitivity, stiffness or reduced confidence. Difficulty kneeling does not, by itself, mean the replacement is damaged. Wait until the wound has healed and your team advises that you can try. Your physiotherapist can demonstrate a gradual approach; do not force a painful position.

Everyday life & wellbeing
Sex and intimacy after knee replacement
When can I have sex after knee replacement?
There is no single waiting period for everyone. Follow your wound-care instructions and surgical restrictions. You should be able to move into and out of your intended position comfortably while protecting the healing knee.
What do British and American recommendations say?
Some NHS guidance permits a return when you feel comfortable and able. AAHKS describes many patients returning within one to three months. This does not mean everyone must wait three months, or that comfort immediately after surgery is sufficient on its own.
Sources: United Lincolnshire Hospitals: knee replacement questions; AAHKS: sexual activity after knee replacement.
Which positions may be more comfortable?
Choose a supported position that avoids pressure on the wound, painful deep bending and twisting through the operated leg. Lying on your back or side may be more comfortable than kneeling. These are comfort suggestions, not guarantees of suitability.
Pillows can provide temporary support. This is not advice to rest or sleep for prolonged periods with the knee held bent over a pillow. Avoid kneeling until your team advises that you can try, and change position rather than forcing movement.

What if intimacy remains difficult?
Pain, stiffness, fatigue and concerns about the joint can affect intimacy. Discuss persistent difficulties confidentially with your team. Recovery may improve comfort and movement, but surgery does not guarantee comfortable kneeling or resolve every sexual difficulty.
