How long does recovery take after knee replacement?
Most people return to normal daily activities within 3 to 6 weeks after total knee replacement. Full recovery can take several months or longer. Your age, general health, and your knee's condition before surgery all affect the timing.
A typical timeline
These are general guides from the UK National Health Service and the American Academy of Orthopaedic Surgeons. Your own plan may differ. The wound closure row follows this clinic's practice.
| When | What usually happens |
|---|---|
| Hours after surgery | Knee exercises can begin. Nurses and physiotherapists help you start walking with crutches or a frame. |
| 1 to 4 days | You usually leave hospital once you move around safely and show no signs of complications. |
| Day 14 | The adhesive mesh closing the wound is removed. |
| 3 to 6 weeks | Most normal daily activities resume. Some pain with activity and at night is common during this period. |
| 4 to 6 weeks | Many people resume driving. UK guidance advises waiting at least 6 weeks. Check with your doctor first. |
| About 6 weeks | You may try walking without an aid if you feel ready. A follow-up review often happens around now. |
| 6 to 12 weeks | Many people return to work. Physical jobs may take longer. |
| First 3 months | Avoid household tasks that involve heavy lifting or moving heavy objects. |
| Several months or longer | Strength, movement and comfort continue to improve. |
What helps recovery
- Follow your exercise programme several times a day. Early exercise helps long-term strength and movement.
- Build up your walking gradually, first at home and then outside.
- Prepare your home before surgery: handrails, a firm chair with arms, and no loose rugs or cables.
- Arrange help with cooking, shopping and bathing for the first few weeks.
- Use your walking aid and handrails. A fall in the first few weeks can damage the new knee.
When to contact your doctor
Possible blood clot in the leg: increasing calf pain, redness or tenderness above or below the knee, or new swelling in the calf, ankle or foot.
Possible infection: a fever above 37.8°C that persists, chills, increasing redness or swelling of the wound, fluid draining from the wound, or knee pain that increases at rest and with activity.
Go to Accident and Emergency at once for sudden shortness of breath or chest pain. A blood clot may have reached the lungs.
Risks
Serious complications such as joint infection occur in fewer than 2% of patients in American guidance. Other risks include blood clots, stiffness, continued pain, implant wear or loosening, and nerve or blood vessel injury. Long-term illnesses can raise these risks.
How your knee may feel long term
- Most people can nearly straighten the knee and bend it enough for stairs and getting into a car. Full movement is uncommon.
- Kneeling may be uncomfortable, but American guidance says it is not harmful. Ask when you may start.
- Numbness around the scar and clicking from the implant are common. They often lessen over time.
- Walking, swimming, golf, cycling and other low-impact activities are realistic goals. Most surgeons advise against running and jumping sports.
- The implant can set off airport metal detectors.
More than 90% of modern total knee replacements still function well 15 years after surgery, according to the American Academy of Orthopaedic Surgeons.
