Patellofemoral pain syndrome is a painful knee condition and one of the causes of anterior knee pain. It involves the damage of the cartilage, a connective tissue consisting of the gel-like substance collagen, located behind the kneecap (patella). This condition predominantly affects adolescents.
Chondromalacia patellae can occur as a result of knee injuries or participation in sports activities that involve prolonged bending of the knee, such as horse-riding. This repetitive motion may lead to weakening of the inner portion of the quadriceps muscle located at the front of the thigh, causing the patella to tilt and rub against the lower end of the femur (thigh bone) when the knee is straightened. This friction causes the cartilage covering both bones to become rough, resulting in pain and tenderness.
The treatment for chondromalacia patellae typically involves the use of analgesic drugs (painkillers) to alleviate pain, along with exercises aimed at strengthening the thigh muscles. In rare cases, surgery may be necessary as a treatment option.
