Patella Injuries
Cartilage on the back surface of the patella (kneecap) helps the knee move smoothly. But injury, aging, or overuse may damage this cartilage. Or, the kneecap itself doesn't stay centered. These problems may restrict leg movement or cause knee pain.
Assessing the Problem
You may have rough, painful cartilage behind the kneecap. This problem is called chondromalacia. Or you may have a tracking problem. This means your kneecap does not stay centered when you bend your knee.
Repairing the Damage
Rough patellar cartilage may be shaved, or smoothed with a laser. If your kneecap does not stay centered, exercise may strengthen the muscles that hold the kneecap in place. In some cases, your surgeon may perform a lateral release. In this procedure, tissue is cut to lessen the pull on your kneecap.
Your Recovery
Recovery may take from 4 weeks to 4 months. To help your knee heal, you may be asked to do some or all of the following:
- Wear a compression dressing if you've had a lateral release.
- Use crutches as instructed.
- Exercise to increase your knee's range of motion and build muscles that help keep your kneecap centered.
