What It Is

Tendons are fibrous cords of tissue connecting the muscles to the bones. They are strong, thick, tough structures and are capable of absorbing significant force. However, if the load applied to the tendon is too great, the tendon can rupture. In the most severe hamstring injuries, the tendon tears completely away from the bone, sometimes pulling a small piece of bone away with it; this is called an avulsion injury (AAOS, n.d.). Like other hamstring injuries, these are caused by large, sudden loads (AAOS, n.d.). This is a significant injury that can take several months to recover from (NHS, 2025), although most people who have the tendon surgically repaired are able to return to sport (Jokela et al., 2022).

Hamstring Tendon Rupture Anatomy

Hamstring muscles run down the back of the thigh. Three hamstring muscles make up the area: the semitendinosus, the biceps femoris and the semimembranosus. They begin at the bottom of the pelvis, on a bone called the ischial tuberosity (your "sitting bone"). They cross the knee joint and end at the top of the lower leg. Hamstring muscle fibres join with the tough connective tissue of the tendons near the places where the tendons attach to the bones. The hamstring muscles help you to extend your leg straight back and to bend your knee (AAOS, n.d.).

Hamstring tendons can rupture at either end, and any of the three hamstring muscles can be affected. Tears from the pelvis are more common than tears from the shin bone (AAOS, n.d.).

With a severe hamstring injury you may feel a sharp pain in the back of the leg and a snapping sensation, or hear a "pop". The back of the thigh may become tender, swollen and bruised, and you may have difficulty standing or walking on the leg (NHS, 2025). If you think you may have ruptured your hamstring tendon, seek medical attention as soon as possible, either at the hospital or with a doctor. The injury can then be assessed, and an X-ray or MRI scan may be used to find out exactly what has happened (AAOS, n.d.).
