Chondromalacia patellae is a medical condition characterized by the softening and breakdown of the cartilage that lines the underside of the patella (kneecap). This condition is also commonly referred to as runner's knee due to its prevalence among athletes, particularly those involved in high-impact sports.

Etiology

The exact cause of chondromalacia patellae is not fully understood, but it is believed to be associated with overuse or injury to the knee joint. Other contributing factors may include muscle weakness or imbalance, improper knee alignment, and age.

Symptoms

The primary symptom of chondromalacia patellae is pain in the front of the knee, which is often exacerbated by physical activities such as running, jumping, or climbing stairs. Other symptoms may include a grinding or clicking sensation in the knee, and knee stiffness after prolonged periods of sitting.

Diagnosis

Diagnosis of chondromalacia patellae typically involves a physical examination of the knee, during which the doctor may apply pressure to the knee or ask the patient to perform certain movements to assess pain and range of motion. Imaging tests such as X-rays or magnetic resonance imaging (MRI) may also be used to visualize the knee joint and assess the condition of the cartilage.

Treatment

Treatment for chondromalacia patellae primarily involves conservative measures aimed at reducing pain and inflammation, and improving knee function. This may include rest, ice, compression, and elevation (RICE), as well as physical therapy exercises to strengthen the muscles around the knee. In severe cases, surgical intervention may be necessary.
