The exact cause of chondromalacia is not known, but it is believed to be caused by repetitive stress or trauma to the kneecap. It is most commonly seen in athletes who participate in high-impact sports, such as running, basketball, or soccer. However, it can also affect non-athletes who perform activities that put stress on the knees, such as squatting or climbing stairs.
The most common symptom of chondromalacia is pain in the front of the knee. The pain is usually worse when bending the knee, climbing stairs, or sitting for long periods. Some people may also experience a grinding or popping sensation when moving the knee. Swelling and stiffness in the knee may also be present.
Treatment for chondromalacia depends on the severity of the condition. In mild cases, rest, ice, and over-the-counter pain medications may be enough to relieve symptoms. Physical therapy may also be recommended to strengthen the muscles around the knee and improve flexibility. In more severe cases, surgery may be necessary to repair the damaged cartilage.
