Featuring Dr. Grant Lum, MD, CCFP, Dip Sports Med, Sports Medicine Physician Video Title:What is Patellar Instability of the Knee and How Is It Treated? Duration: 1 minute, 21 seconds

Patellar disc location is a condition where the patella or kneecap is actually displaced from the leg altogether.

Usually this happens in trauma situations. So when someone has a fall or a bad twist to the knee then the kneecap can actually dislocate or pop off. When the kneecap doesn't dislocate completely, we call that a subluxation. But both of these conditions would fall under the term of patellar instability. It means that the kneecap's not stable.

That type of injury leads to a stretching or tearing of something called the retinaculum. That's the piece of tissue that anchors the kneecap on. In some cases when that's been torn completely, then the kneecap becomes so unstable that you can dislocate your kneecap very easily doing day-to-day things like getting out of your car or even turning to go down the hallway. In those kinds of situations then surgery may be necessary.

In lesser situations where the kneecap is only mildly unstable, we can make a lot of progress doing things like therapy to try and strengthen the muscles or we can apply a brace to play the role of that retinaculum so that the brace holds the kneecap in place and prevents it from subluxing or dislocating.

If you've had a patellar subluxation or dislocation or if you have further questions, there are various treatment options available to you.
