Knee Replacement Recovery: What to Expect Week by Week
A practical guide to early walking, swelling, exercises, driving and return to daily activities after total knee replacement.
Hospital and the first week
Early priorities are safe mobilisation, pain control, wound care, clot prevention and learning a simple exercise programme. A physiotherapist teaches transfers, walking with an aid and stair technique where needed.
The knee is expected to be swollen and bruised. Elevation, appropriate cold therapy, medication and regular short walks are usually more useful than one long, exhausting exercise session.
Weeks two to six
Walking distance and confidence usually increase, while the focus remains on straightening the knee, progressively improving bend and rebuilding quadriceps control. Many patients still need an aid outdoors during part of this phase.
Driving depends on which knee was operated on, medication use, reaction time and the ability to control the vehicle safely. Return to desk work may be possible earlier than physical work, but prolonged sitting can increase swelling.
Six weeks to three months
Daily activities often become easier and structured strengthening progresses. Swelling may still increase later in the day or after a demanding session. Improvement is rarely a perfectly straight line.
Low-impact exercise such as cycling, walking and pool work may be introduced according to wound healing, movement and clinical advice.
When to contact the treating team
Seek prompt advice for increasing wound redness or drainage, fever, new calf swelling, chest pain, shortness of breath, a sudden loss of movement, or pain that is unexpectedly escalating rather than gradually settling.
Your own discharge instructions take priority because medication, wound closure, medical risk and rehabilitation protocols differ between patients.
Common questions
Questions patients often ask.
How much knee bend should I have after surgery?
There is no single number that every patient must reach on the same day. Pre-operative stiffness, swelling and pain vary. Steady functional progress and full extension are important goals.
How long does swelling last after knee replacement?
Noticeable swelling commonly persists for weeks and milder swelling may continue for several months. A sudden increase, especially with calf pain or illness, should be assessed.
When can I sleep normally again?
Sleep disturbance is common early in recovery and usually improves as pain, medication timing and movement settle. Persistent severe night pain or other concerning symptoms should be discussed with the treating team.
