Patellar Dislocation and Subluxation With Phase I Rehab

Patellar dislocation and patellar subluxation are injuries that happen when the kneecap (patella) slips out of its normal position in a groove in the end of the thighbone (femur). In a patellar dislocation, the kneecap slips all the way out of the groove. In a patellar disoclation, it slips partly out of the goove.

CAUSES

This injury may be caused by:

A hit to the knee.

Firmly pointing the foot outward and bending the knee with the thigh turned inward. This can happen when twisting or pivoting.

RISK FACTORS

This injury is more likely to develop in people who certain kinds of sports, including:

Contact sports, such as soccer.

Sports that require jumping, such as

In some cases, your health care provider may look inside your knee joint with an instrument much like a pencil-sized telescope (arthroscope). This may be done to make sure you have no loose cartilage in your joint.

TREATMENT

This condition is treated by moving the patella back into position. In many cases, this can be done by hand. However, sometimes it must be done with surgery. Treatment may also involve:

Wearing a knee brace to keep your knee from moving (immobilized) while it heals.

Doing exercises to help improve strength and movement in your knee.

Taking medicine to help with pain and inflammation.

Applying ice to the knee to help with pain and inflammation.

Surgery to prevent the patella from slipping out of place. This may be needed if the injury happens often.
