The lateral thigh muscles are mainly the following: 1, the lateral femoral muscles of the anterior lateral thigh: one of the muscles of the anterior thigh group, which can mainly play the role of straightening the knee joint and stabilizing the knee joint; 2, the broad fascia tensor muscle of the upper lateral thigh: it can play the role of protecting the hip joint and stabilizing the hip joint, starting at the iliac bone and ending at the lateral tibial bone. The broad fascia tensor continues downward into the iliotibial bundle and ends at the lateral tibial point, which can play the role of hip abduction. Functional exercises for the muscles around the hip and knee joints are generally recommended for patients with hip and knee degeneration to stabilize the joint and reduce joint loading, thereby reducing joint degeneration.
