Knee - Knee Cap Injury - Causes and Risk Factors

Causes of Patello-Femoral Pain Syndrome (PFS)

Structural alignment and muscle weakness or imbalance may cause the patella (kneecap) to track improperly on the femur (tight bone) during movement. This results in excessive wear and teaar on the undersurface of the kneecap in contact with the tight bone leading to pain around the kneecap.

Knee - Knee Cap Injury - Diagnosis

Diagnosis is usually made on history, and clinical examination and x-ray of the knee may be useful to assess the position of the kneecap and to rule out other conditions.

Knee - Knee Cap Injury - Treatments

Treatment includes avoiding activities that will place more stress on the knee and medication to reduce pain, swelling and inflammation. Physiotherapy, when the pain lessens, may be recommended particularly exercises to strengthen quadricep muscles.

Your surgeon may explore the option of surgery should your symptoms not improve.
