 Hello, I'm Dr. Sunil Kini, consultant joint replacement and arthroscopy surgeon at Manipar Hospital's Bangalore. It's very important to continue the physiotherapy after knee replacement, so knee surgery is just doing half the work, the next half is how the patient is motivated and gets on with the physiotherapy. So physiotherapy is important for many reasons, one is to reduce the pain, one is to increase the range of motion and one is to strengthen the muscles, these are three goals. Physiotherapy includes certain exercises such as the quadriceps strengthening, which you also call the thigh squeeze test, the hamstring exercises, exercises to strengthen the calf muscles after a certain period of time. It's also important that the patient increases the walking distance for a period of time, say about half a mile by about four to six weeks and progressively increase it day by day. It's also important to do other stretch of exercises. The physiotherapy is also important for patients who are in the early stages of arthritis to prevent the progression of arthritis. So when we say arthritis we grade it into one, two, three, four, one being the earliest stage and four wherein it's bone on bone. So people in first, second and even in certain stages of grade three arthritis, physiotherapy is very, very important, which includes your quadriceps exercises, hamstring, your calf strengthening exercises, which would actually build up your muscles around the knee and put lesser strain on the joints and would increase the longevity. For patients who are advice surgery also, it helps to start the physiotherapy right before surgery so that patients regain the range of motion and strengthen the muscles, which will go a long way for the physiotherapy after surgery as well.
