Overview
Patellofemoral pain syndrome is pain in the front of the knee. (The patella is the kneecap, and the femur is the thigh bone.) It's caused by overuse, weak thigh muscles (quadriceps), or a problem with the way the kneecap moves. Extra weight may also cause this syndrome.
In some cases, the kneecap does not move, or track, in a normal way. Your child may have knee pain when running, walking down hills or steps, or doing other activities. Sitting for a long time also can cause knee pain.
Your child's knee pain may get better with home care. Exercises to make the quadriceps stronger can also help. Losing weight, if your child needs 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 child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
