Post Knee Replacement Surgery Care


A patient’s recovery and rehabilitation plan are crucial to the overall success of knee replacement surgery. Typically, knee replacement patients can leave the hospital within 1 to 5 days and they can take care of themselves and resume most activities 6weeks after surgery. The majority of patients are 90% recovered after 3months, though it can take 6months or longer before they are 100% recovered. When you have total knee replacement (TKR) surgery, recovery and rehabilitation is a crucial stage. In this stage, you’ll get back on your feet and return to an active lifestyle. A replacement knee  may feel different than a natural knee. Their awareness was most notable when climbing stairs or rising from a chair.

What to expect after surgery?

Post Knee Replacement surgery

After Knee Replacement Surgery, the patient will wake up from anaesthesia and begin to regain feeling in his or her legs. Within 24 hours, if the pain is under control, the patient may be asked to stand up and take a few steps with the aid of a physical therapist or a walker. Patients who get up and bear some weight (with assistance) on their new knees soon after surgery tend to recover more quickly than patients who do not. Some doctors prescribe continuous passive motion (CPM) machines after surgery.

A CPM machine slowly moves the affected leg, causing it to be repeatedly straightened and bent, while the patient is lying on his or her back. A patient may use a CPM machine for up to 8 hours a day, in between sleeping and physical therapy. CPM machines help patients regain range of motion more quickly, which can facilitate faster hospital discharge.

How long does it take to recover from total knee replacement surgery?

Within the first 24 hours, your physical therapist (PT) will help you to stand up and walk using an assistive device. Assistive devices include walkers, crutches, and canes. A nurse or occupational therapist will help you with tasks such as changing the bandage, dressing, bathing and using the toilet. They may ask you to sit at the side of the bed, walk a few steps, and transfer yourself to a bedside commode. On the second day, you might walk for brief periods using an assistive device. As you recover from surgery, your activity level will increase gradually. Increase knee flexion (bending) by at least 10 degrees if possible

At the point of 13th week, you should have much less pain. Keep talking to your healthcare team and avoid starting any new activities before checking with them first. Your knee will keep on improving gradually over time, and pain will reduce. The American Association of Hip and Knee Surgeons (AAHKS) say that it can take up to 3 months to return to most activities, and 6months to a year before your knee is as strong and resilient as it can be. Stay in touch with your medical team and have regular checkups to make sure that your knee is staying healthy. The AAHKS recommends seeing your surgeon every 3 to 5 years after TKR.

Medication and Exercises

The breathing exercises that you need to do after surgery helps you to avoid fluid buildup and keep your lungs and bronchial tubes clear.
Moving your ankles and doing some exercises while lying in bed after surgery can help maintain circulation and reduce the risk of blood clots. These may include:

  • Ankle pumps: Push your foot up and down several times every 5–10 minutes.
  • Ankle rotations: Move your ankle inward and outward five times, repeating this exercise three to four times each day.
  • Bed supported knee bends: Lying down, slide your foot back toward your buttock, keeping your heel on the bed.

If a blood clot develops in your leg, this is deep vein thrombosis (DVT). If a clot breaks off and moves to the lung, a pulmonary embolism can develop. It is potentially a severe complication, but keeping the circulation moving can help reduce the risk. Physical therapy helps you to stand up as soon as possible, get you moving and helps you adjust to your new knee. Record your mobility, range of motion, and exercise progress. The sooner you begin your rehabilitation, the better your chances for a successful outcome and speedy recovery. It’s important to resume normal activities as soon as possible after leaving the hospital. It is also essential to:

  • Attend all appointments with your doctor and physical therapist.
  • Practice the exercises your physical therapist has prescribed.
  • Wear a compression hose for as long as your doctor advises.

By the time you go home from the hospital, you should be eating a normal diet. Continue to drink plenty of fluids and avoid alcohol. Depending on the type of activities you do on the job and the speed of your recovery, it may take from several days to several weeks before you can return to work.


Regular exercise to restore strength and mobility to your knee and a gradual return to everyday activities are important for your full recovery after knee replacement. They may recommend you to exercise for 20 to 30 minutes, 2 or 3 times a day and walk for 30 minutes, 2 or 3 times a day during your early recovery. Once you have regained independence for short distances and a few steps, you may increase your activity. The pain of your knee problems before surgery and the pain and swelling after surgery have weakened your knee.

Total knee arthroplasty improves the functional ability of the patient and the ability of the patient to get back to the pre-disease state, which is to have a pain free mobile joint, as reflected by the improvement in the post-op knee clinical score and knee functional score.
