Definition of Condromalacia Patella
Chondromalacia patella is a common cause of kneecap pain or anterior knee pain. Often called “Runner’s Knee,” this condition often affects young, otherwise healthy athletes.
Chondromalacia is due to an irritation of the undersurface of the kneecap. The undersurface of the kneecap, or patella, is covered with a layer of smooth cartilage. This cartilage normally glides effortlessly across the knee during bending of the joint. However, in some individuals, the kneecap tends to rub against one side of the knee joint, and the cartilage surface become irritated, and knee pain is the result.
What happens to the cartilage with chondromalacia?
Chondromalacia is due to changes of the deepest layers of cartilage, causing blistering of the surface cartilage. The pattern of cartilage damage seen with chondromalacia is distinct from the degeneration seen in arthritis, and the damage from chondromalacia is thought to be capable of repair, unlike that seen with arthritis.
Who gets chondromalacia?
Chondromalacia is interesting in that it often strikes young, otherwise healthy, athletic individuals. Women are more commonly affected with chondromalacia. Exactly why this is the case is unknown, but it is thought to have to do with anatomical differences between men and women, in which women experience increased lateral forces on the patella.
