At some point in their lives, most Southern Californians who engage in sports such as running, skiing, cycling, and soccer find themselves with knee pain. Informally known as “runner’s knee,” this term may be used to describe various aches, pains and injuries to the knee including anterior knee pain syndrome, patellofemoral malalignment, and chondromalacia patella. Depending upon the cause of the knee pain, Dr. Nadel, one of Southern California’s leading sports injury specialists will determine the appropriate course of treatment. In mild cases, Los Angeles area patients with runner’s knee may only need to rest and ice the knee. In other cases a knee brace may be indicated. In other cases, arthroscopic surgery may be performed by Dr. Nadel at West Hills Hospital.
