A knee replacement is an operation to replace the damaged or worn parts of the thigh and shin bones which form the knee joint.
During the operation, a single incision (usually 15 to 30cm long) is made down the front of the knee. The kneecap is moved to one side so the joint can be reached. The damaged or worn parts are replaced with metal and plastic parts that glide over each other smoothly. When the joint has been replaced, the incision is closed with stitches or clips.A knee replacement usually takes one to two hours and normally requires a hospital stay of up to five nights.
While you are in hospital, a physiotherapist will visit you every day to guide you through exercises to help you recover. You will be encouraged to move your new knee from the first day after the operation. You will be discharged once you can walk safely with sticks or crutches - usually after 3-5 days.
