Alternate Names : Patellofemoral syndrome
Chondromalacia patella is the softening and degeneration of the tissue (cartilage) underneath the kneecap (patella).
Overview, Causes, & Risk Factors
Chondromalacia patella that occurs in adolescents and young adults is thought to be related to overuse, injury, or too much force on the knee. It is more common in females. Many young people have a slight problem with the position of the kneecap.
Chondromalacia patella may also be a sign of arthritis of the kneecap, which is usually seen in older individuals.
People who have previously had a dislocation, fracture, or other injury to the kneecap may be more likely to get chondromalacia.

Chondromalacia of the patella
Chondromalacia of the patella is the grating or grinding sensation during extension of the knee. The cause is thought to be related to overuse, trauma and/or abnormal forces on the knee, such as a mildly abnormal alignment of the patella (knee cap) and femur. Symptoms include knee tenderness, pain in the knee after sitting for a prolonged period of time, knee pain that is worse with stairs or getting out of a chair, and a grating sensation in the knee.
