Patellofemoral pain syndrome is pain in the front of the knee. It is caused by overuse, weak thigh muscles (quadriceps), or a problem with the way the kneecap moves. Extra weight may also cause this syndrome.
The patella is the kneecap, and the femur is the thigh bone.
In some cases, the kneecap does not move, or track, in a normal way. You may have knee pain when you run, walk down hills or steps, or do other activities. Sitting for a long time also can cause knee pain.
Your knee pain may get better with medicines for pain and swelling. Exercises to make your quadriceps stronger can also help. Losing weight, if you need to, may also help with pain.
Pain in the front of the knee can also be caused by chondromalacia. In this problem, the underside of the knee cartilage wears down and frays. Cartilage is a rubbery tissue that cushions joints.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Watch closely for changes in your health, and be sure to contact your doctor or nurse call line if:
