Kneecap Dislocations
Treatment of a Dislocated Kneecap
Manipulation to move the kneecap back in place Usually an elastic bandage and crutches or sometimes a knee immobilizer If the kneecap remains unstable, surgery Doctors move the dislocated kneecap gently back in place (called reduction). Usually, no sedative or analgesic is necessary. Then the knee is checked for stability by moving it through its range of motion (flexing and extending the knee). If the knee is stable, it is wrapped in an elastic bandage, and people are given crutches to use. If the knee is unstable, a knee immobilizer is applied. This device supports the knee and keeps it from bending. The immobilizer is worn for several days. After it is removed, physical therapy is needed to restore muscle strength and to improve the knee's range of motion. The joint may need to be repaired surgically by an orthopedic surgeon if any of the following occur: A bone is fractured. Cartilage in the joint is injured. The knee continues to be unstable after initial treatment. Surgery may be done using a small viewing tube inserted in the joint through a tiny incision ( Surgery Through a Keyhole ), or open surgery (requiring a larger incision) may be done.
