This surgery is called internal fixation. After surgery the doctor may put your knee in a cast. He or she will place the cast around the injured area to immobilize the joint above and below the fracture site. Immobilization of a body part can cause joints to stiffen and muscles to weaken in uninjured areas. You will also learn isometric exercises to strengthen the fractured part.
Isometric exercises avoid movement.
You create tension by contracting the muscle, holding the tension, and then releasing it without moving the joint. Healing times depend on which bone was broken, the type of fracture, the type of treatment, and how well you heal. To help take care of yourself, follow the full course of treatment your doctor prescribes. Get plenty of rest. Elevate the leg when possible to reduce swelling.
