 Hello, I'm Dr. Sunil Kini, consultant joint replacement and arthroscopy surgeon at Manipal Hospital's Bangalore. To start off with hip and knee replacements, I'm one of the most successful joint replacements surgeries all around the globe. The recovery after knee replacement starts immediately after surgery. First, we start mobilizing the patient or walking the patient on the same day or probably the next day after surgery. We start with gentle knee range of motion or bending exercises. Also make the patient first to stand up and then even walk a few steps if possible on the first day itself. The goal is to get the knee to bend about 90 degrees by the time the patient is discharged. We also have set a few more goals at the time of discharge. Firstly, the patient should be able to use the toilet themselves. The patient should walk a considerable distance out of the ward. The patient should have pain-free joint. The range of motion as I previously said to about 90 degrees. So knee pain and swelling should be at a minimum during time of discharge. Once the patient goes home, we have a physiotherapy team which visits the patient home. It's very important that the physiotherapy continues for, say, four or six weeks after surgery and not just during the hospital admission. So the goal at home is to continue with the knee exercises which includes the strengthening of the muscles around the knee, the quadriceps, the hamstring muscles. It also includes improving the range of motion to, say, maximum to about 130 degrees, which is possible. It also includes that the patient's swelling and pain considerably goes down. It is important to note that the improvement in knee joint surgery in terms of pain can occur up to about three months after surgery so that anyone comes to me at three months down the line with some amount of pain that is expected. Similarly, the swelling can be there for a considerable duration, say, six months or 12 months after surgery, which is considered normal.
