After removing the stitches and the ankle brace, patients are usually able to begin formal physical therapy. As the torn or ruptured ligament heals, the body responds by forming too much scar tissue along the front and side of the ankle joint. This allows the shelf of the heelbone to come into contact with the back of the tibia, pinching the soft tissues in between. 300.00 The surgeon inserts the arthroscope to see which area of the tendons or joint capsule are irritated and thickened.
