What is the primary cause of Patellofemoral Pain Syndrome?
The exact cause of patellofemoral pain syndrome (PFPS) remains elusive, but it is believed to result from a combination of factors that lead to increased stress on the kneecap and its surrounding structures. These factors can include poor biomechanics, muscle imbalances, tightness in the hip flexors or iliotibial band, or weak quadriceps and gluteal muscles. Repetitive activities like running or jumping can also contribute to the development of PFPS. Symptoms include pain around the kneecap, difficulty in extending the knee, and crepitus (a grinding sensation) when moving the joint. Treatment options include conservative measures such as ice, rest, and physical therapy, which focuses on strengthening the muscles surrounding the knee and improving flexibility.
