What is a patellar tracking disorder?

Patellar tracking disorder is a condition where the kneecap changes out of position as the leg is bent or straightened. The kneecap twists too far toward the outside portion of the leg. In some people, it twists toward the inside part of the leg. The knee joint is a hinge that joins the two bones of the lower leg with the thigh bone. The knee cap is located at the end of the thigh bone, and held by tendons on the top and bottom, and on the sides is held by the ligaments. A layer of cartilage lines the underside portion of the kneecap, and helps it to glide along the groove in the thighbone. When there is a problem in any of these parts found inside and around the knee, it can cause patellar tracking disorder.

A patellar tracking disorder can be caused by the way the knee is shaped. Knee problems include a flat or small kneecap, knock-knee, an elongated patellar tendon or a superficial groove at the endpoint of the thighbone. The muscles found in front of the thigh which is the quadriceps are weak and out of balance. A loose or too tight ligaments, tendons or muscles can also cause a patellar tracking disorder. A damaged cartilage in the kneecap can also cause this condition. Individuals who are overweight, run, or play sports that require repeated movements like jumping, knee bending or by squatting can cause patellar tracking disorder.
