Total Knee Replacement (TKR)

Rehabilitation - Recovery

How long does it take to recover after TKR?

Most patients undergoing total knee replacement surgery want to know when they’ll be able to return to their normal life. Questions about “recovery time” are common. There are many factors that can affect recovery time, but typically patients can return to normal life activities within 3 to 6 months, but it can take up to 12 months to achieve in some patients.

Short Term Recovery

Short-term recovery involves the early stages of recovery, such as the ability to get out of the hospital bed and be discharged from the hospital. On days 1 or 2, most total knee replacement patients are given a walker to stabilize them. By the third day after the surgery, most patients can go home. Short-term recovery also involves getting off major pain killers and having a full night’s sleep without pills. Once a patient no longer needs walking aids and can walk around the house without pain–in addition to being able to walk two blocks around the house without pain or resting–all of these are considered signs of short-term recovery. The average short-term recovery time for a total knee replacement is about 12 weeks.

Long-Term Recovery

Long-term recovery involves the complete healing of your surgical wound and internal soft tissues. When you are ready to return to work and the activities of daily living, you are on the way to achieving full term recovery. Another indicator is when the your finally feels normal again. The average long-term recovery for total knee replacement patients is between 3 and 6 months.

There are a number of contributing factors that influence recovery time. A motivated well informed patient is the best start. A positive attitude is everything. Patients should be prepared for diligent work, some pain and an expectation that the future is going to be bright. Having access to information about knee replacement surgery and a strong support network is also important to recovery. Make sure you have some close family or friends able to assist and help you once you are home. Having someone help you do the groceries, cook or clean for a short period of time is really helpful whilst you continue to recover when you go home.

Day 1 to Week 3

What to expect

You will have a large bulky dressing on your leg when you awake after your surgery. This will be removed approximately 72 hours (3 days) after your surgery by the nursing staff. You will be required to wear elastic stockings (TEDS) for six weeks following your surgery.

It is recommended that you apply ice to your knee to help reduce pain and swelling, up to 30 minutes out of every 2 hours. It is normal to have knee swelling and bruising following the surgery. It will often increase as your activity level increases.

Change knee position at least once an hour, while awake, to avoid stiffness Walker or crutches should be used until discontinued by surgeon or physiotherapy. If your knee swells, rest and elevate it. Apply ice. It should settle over time. If you are concerned, contact Dr Damasena in his rooms on 90819305. You will not be allowed to swim, either in a pool or the surf, until these wounds are completely healed (approximately 10 to 14 days)
