A term first used by Dr George Sheehan in the 1970s to describe a rather enigmatic running injury characterized by pain around the kneecap, which occurs during running, but is not linked to any specific external trauma. The pain worsens with the distance of the run, and makes walking up and down stairs difficult. It is not usually resolved by conventional treatments, such as cortisone injections. It was first thought to be a form of chondromalaria patellae, which would suggest that running may cause degeneration of articular cartilage. However, the pain associated with runner's knee is usually on the inner or outer border of the kneecap. The condition is now thought to be a form of patellofemoral pain syndrome. The term runner's knee has also been applied to the pain on the outside of the knee associated with iliotibial band syndrome. Running on cambered roads and excessive pronation increase the risk of suffering from painful knees.
