What Is Chondromalacia?
Also known as runner’s knee, chondromalacia patellae is a condition where cartilage under the kneecap is damaged. The cartilage beneath the kneecap naturally absorbs shock from running or walking and is susceptible to damage from overuse or through another injury. Because of its association with running or jogging, the ages most commonly affected are between 14 and 40. Osteoarthritis can form with damage to the articular cartilage, which may become worn down with repeated episodes of chondromalacia.
Causes & Symptoms
The causes of chondromalacia include the following:
trauma, such as a fracture or dislocation
muscle imbalance around the knee
overuse such as bending or twisting
poorly aligned bones near the knee
meniscus injury
rheumatoid or osteoarthritis
knee joint infection
bleeding inside the knee joint
