Chondromalacia Patellae ( CMP )

Chondromalacia patellae, a chronic knee pain …

Chondromalacia patellae, also called CMP or runner’s knee, is the most common cause of knee pain. This disease is common in young, athletic individuals. It also occur in older adults who are suffered from arthritis of the knee.

In CMP, the cartilage on the undersurface of patella (kneecap) deteriorates and softens.

Normally, CMP affects both gender ( male and female ). But, according to a survey women are twice as likely as men are to develop CMP. It may occurs due to the woman’s wider pelvis increases the angle at which the bones in the knee joint meet.

Causes of CMP :  

Generally, the patella (kneecap) resides over the front of knee joint. In the case of banding the knee, backside of your patella (kneecap) glides over cartilage of the femur, ( thigh bone ) at your knee. In this situation, the tendons and the ligaments attach to your kneecap to your shinbone and thigh muscle. If any of these component doesn’t work properly than it can disturb your kneecap to rub up against the thigh bone. As a result, it generates CMP.

Some situation that may generate CMP, including :
  • Running, skiing or jumping sports puts repetitive stress on the knee joints.
  • Imbalance of muscles between adductors and abductors.
  • Knee surgery.
  • Pain in knee joint
