Hamstring Rupture

Anatomy

The hamstring muscles include: biceps femoris, semimembranosus, and semitendinosus. These muscles act as flexors of the knee joint and extensors of the hip. They also assist with rotation at the knee.

Mechanism of Injury

  • Overstretching or forceful contraction such as in sprinting and hurdling.

Symptoms

  • There is typically a history of sudden onset of pain in the posterior thigh associated with explosive activity. A “pop” may have been heard.
  • Local tenderness is found on palpation with the athlete prone (lying on their front).
  • The hematoma may reach the skin, causing discolouration after a few days.
  • Sometimes a palpable defect can be present.
  • Pain can be felt while flexing the knee or extending the hip against resistance.
