Chondromalacia patellae (also known as CMP) is an inflammation of the underside of the patella and softening of the cartilage.. The cartilage under the kneecap is a natural shock absorber, and overuse, injury, and many other factors can cause increased deterioration and breakdown of the cartilage.
Patellofemoral pain syndrome is the most common cause of knee pain, affecting more than 20% of young adults. [ 1 ] [ 2 ] It occurs about 2.5 times more often in females than males. [ 2 ]

The most common location of plica tissue is along the medial (inside) side of the knee. The plica can tether the patella to the femur, be located between the femur and patella, or be located along the femoral condyle. If the plica tethers the patella to the femoral condyle, the symptoms may cause it to be mistaken for chondromalacia.
In the adult the articular surface is about 12 cm 2 (1.9 sq in) and covered by cartilage, which can reach a maximal thickness of 6 mm (0.24 in) in the centre at about 30 years of age. Owing to the great stress on the patellofemoral joint during resisted knee flexion, the articular cartilage of the patella is among the thickest in the human body.
