Symptoms & Cause
Patella dislocation can be caused by twisting of the lower limb or impact to the patella. Other factors could be a shallow femoral groove or chronic dislocation. A dislocated kneecap can cause other problems even if the bone pops back into place. Ligaments, tendons, muscles, and cartilage in or around the joint may stretch or tear. A piece of bone may break off somewhere in the knee joint causing pain. It is important to be seen by a physician even after the bone has been relocated which sometimes happens spontaneously on its own after the injury. Client’s symptoms could include swelling, tenderness and instability.
