The hamstring muscle group consists of three muscles with respective tendons. The proximal hamstring tendons attach the hamstring muscles to the pelvis and femur. The distal hamstring tendon and muscles connect to the knee joint at the proximal tibia and fibula. Tendon injury to the proximal hamstring is a common cause of hamstring pain. Hamstring tendon inflammation is called tendinitis, while chronic tendonitis and degeneration is hamstring tendinopathy.
The hamstring. muscles with the exception of the short head of the biceps femoris all attach to the pelvis as one common tendon, which when inflamed is called proximal hamstring tendonitis or tendinopathy. The proximal or high portion of the hamstring tendon is the most location of injuries such as a strain, tear, or with trauma, avulsions of the bone. The hamstring can also cause pain behind the knee if the tendonitis is the result of a knee injury.
