What is Patellar Subluxation?
- The patella (kneecap) normally sits in a groove at the center of the bottom end of the thigh bone.
- A patellar subluxation means that the kneecap has briefly slid out of its normal place in that groove.
- In most cases the kneecap moves towards the outside of the body when it slides out of place.
- This can be a one-time event, or it can happen multiple times.
What Causes Patellar Subluxation?
- The most common cause is weakness and/or tightness of certain muscles in the hip and thigh, which can make the knee move differently than it should.
- A direct blow to the front or side of the knee that pushes the kneecap out of its groove.
What are the Symptoms?
- Pain and swelling around or underneath the knee cap
- The knee giving way when walking or running
- Popping in the front of the knee
What Can I Do to Feel Better?
- Rest from anything that causes pain
- Ice for 15-20 minutes as often as once per hour can help control pain and swelling
- Work with an Athletic Trainer or Physical Therapist to strengthen weak muscles and stretch ones that are too tight
When Should I See a Medical Professional?
