Tightness in the broad fascia tensor muscle can cause symptoms such as hip popping, lateral thigh, and knee pain. The vastus tensor muscle is located on the lateral side of the thigh, starting at the anterior superior iliac spine, continuing down to the iliotibial fascia, and ending on the lateral side of the tibial plateau. When contracted, the tensor fasciae latae muscle allows the hip to abduct and rotate in flexion. Tension of the tensor fascia lata muscle increases the friction between the tensor fascia lata muscle and the deep muscle ligaments, resulting in hip popping when walking, accompanied by pain on the lateral side of the hip joint. Tension in the broad fascia tensor muscle will also increase the pulling force of the iliotibial bundle on the outside of the knee, causing an imbalance between the inner and outer sides of the knee during running, which will easily lead to knee pain after running. At the same time, the imbalance between the inside and outside of the knee will also change the patella’s sliding trajectory, which is also easy to cause chondromalacia patella. If the tension and contracture of the broad fascia tensor muscle continues for a long period of time, the tension on the lateral side of the knee joint increases, and it is easy to gradually develop into knee valgus. Broad fascia tensor muscle tension once the pain and other symptoms, it is recommended that patients go to the hospital in a timely manner, check the perfect examination, receive regular treatment.
