Runner's knee is the common term used to describe any one of several conditions that cause pain around the kneecap or patella. These conditions include: anterior knee pain syndrome, patellofemoral malalignment, chondromalacia patella, and iliotibial band syndrome.

​

The cartilage under the kneecap is a natural shock absorber. Chondromalacia patellae may develop when the knee is overused or injured.
