Knee replacement surgery recovery time differs from person to person. After a total knee replacement, most people are out of bed within a day or two, stay in hospital for 2 to 3 days in Dr. Aman's practice (up to about 5 days when other medical conditions need attention), manage light daily activity within a few weeks and reach their functional level over about three to six months, with smaller gains continuing for up to a year. After a partial knee replacement the hospital stay is usually 1 to 2 days, and in most patients early recovery is quicker than after a total replacement.
Knee replacement recovery in stages
Recovery goes in stages. The timings below are typical for total knee replacement, and your own course depends on your fitness, your knee and the operation done.
- In hospital (usually 2 to 3 days): pain control, getting out of bed with a physiotherapist, first walking with a frame or walker, and the first bending and straightening exercises.
- First two weeks at home: walking with support, regular exercises, swelling control and wound care. Tiredness is common.
- Weeks two to six: walking distance and confidence improve, and many people move from a walker to a stick. Light household tasks return.
- Weeks six to twelve: stairs and longer walks get easier, and more of the usual routine returns.
- Three to six months: many people reach their functional level, with strength and endurance still building.
- Up to a year: smaller improvements, and swelling and stiffness settle further.
Everyone moves at a different pace. Comparing your knee with a friend's is rarely useful, because the surgery, the starting fitness and the rehabilitation can all differ.
Physical therapy for knee replacement
Physiotherapy is the part of recovery you control. Regular exercise is what regains movement and strength. Typical elements include:
- ankle pumps and leg movements to keep circulation going
- thigh muscle tightening and straight-leg raises to wake up the quadriceps
- heel slides and sitting knee bends to regain bending
- lying or sitting exercises to straighten the knee fully
- walking practice, then stairs, then balance work
- stationary cycling later, when your physiotherapist allows it
Do the exercises even on days when the knee feels fine, and stop and ask if pain suddenly gets worse. Pre-operative physiotherapy is advised for some patients in Dr. Aman's practice, so that they start surgery fitter and already know the exercises.
Post op knee replacement care at home
- Raise the leg and use cold packs as advised to control swelling.
- Take pain medicines and any blood-thinning treatment exactly as prescribed.
- Keep the wound clean and dry and follow your surgeon's dressing instructions.
- Walk in short, frequent spells through the day.
- Attend follow-up reviews so progress can be checked and the plan adjusted.
Many patients ask about sitting on the floor, sitting cross-legged, squatting or kneeling. Whether these are possible depends on how much bend your knee reaches, and Dr. Aman usually decides this patient by patient at follow-up visits, so there is no single rule that fits everyone.
Driving, work and travel
In Dr. Aman's practice, driving usually restarts at about four weeks after a total knee replacement, once you control the leg fully, can brake without hesitation and no longer need strong pain medicine. Desk work usually returns at about three to four weeks, before physical work. The exact timing depends on which knee was operated on, how you are moving and your surgeon's advice. Long journeys need breaks to stand and move the legs, because sitting for hours raises the risk of clots.
What helps recovery go well
- Better strength and fitness before surgery.
- Well-controlled diabetes, blood pressure and weight.
- Not smoking.
- Doing the prescribed exercises regularly.
- Following the advice on walking aids and activity.
People who are active before surgery tend to recover better than those who have been bedridden, and a pre-operative assessment is done so that risk can usually be anticipated; surgery is sometimes not advised for a patient who is medically unfit. Recovery can be slower with poorly controlled diabetes, other painful joints, or a very stiff or deformed knee before surgery. The stages above describe total knee replacement. After a partial knee replacement the hospital stay is usually 1 to 2 days, and in most patients early recovery is quicker than after a total replacement, while robotic-arm assisted surgery has not been shown to speed recovery. More on the options is in our guide to total knee replacement and on the robotic knee replacement page.
Warning signs after knee replacement
Contact your surgeon the same day for a fever, increasing redness, warmth or discharge at the wound, pain that is getting worse, or a swollen, tender calf. Chest pain or sudden breathlessness is an emergency and needs immediate hospital care.
