We will first do an arthroscopic examination on your joint under a general anaesthetic and if necessary correct any abnormality in the joint itself. Computer assisted surgery is used to accurately measure the degree of correction. This is followed by the insertion of a specific size of bone wedge in the upper leg just above the knee. The bone wedge is obtained from the bone bank. The bone is fixed with a plate and screws, giving a very stable fixation. The operating time is approximately 90 minutes.
