Patellar Tracking Disorder
What is patellar tracking disorder?
Patellar tracking disorder means that the kneecap (patella) shifts out of place as the leg bends or straightens. In most cases, the kneecap shifts too far toward the outside of the leg. In a few people, it shifts toward the inside.
Your knee joint is a complex hinge that joins the two bones of the lower leg with the thighbone.
A problem with any of these parts in or around the knee can lead to patellar tracking disorder.

How is it treated?
Patellar tracking disorder can be a frustrating problem, but be patient. Most people feel better after a few months of treatment. As a rule, the longer you have had this problem, the longer it will take to get better.

If you don't have severe pain or other signs of a dislocated kneecap, you can try home treatment for a week or two to see if it will reduce your pain.
As your knee pain starts to decrease, do exercises to increase strength and flexibility in your leg and hip. Your doctor or a physical therapist can help you plan an exercise program that fits your condition. You will probably start with one or two exercises and add others over time.

Surgery usually isn't needed for patellar tracking disorder. You may need surgery if your kneecap dislocates many times or other treatments haven't worked. There are several types of surgery that can correct a tracking problem. You and your doctor can decide which surgery is best for you.
Can patellar tracking disorder be prevented?
Sometimes knee problems run in the family. If a family member has knee pain, you may want to take steps to help prevent this problem.
