Dr Yu is an orthopaedic surgeon who performs surgery to repair proximal hamstring tears of the hip.

What is a proximal hamstring repair?

Dr Yu performs this procedure to reattach torn hamstring tendons to the pelvis. This operation is typically recommended for individuals who have sustained a complete avulsion (tear) of one or more hamstring tendons from their origin at the ischial tuberosity — the bony prominence at the bottom of the pelvis. This injury often results from sudden or forceful stretching of the leg, such as in a fall or sports-related trauma.

When is surgery needed?

Surgical repair is considered in the following situations:

  • Complete tendon avulsion (where tendons are fully torn from the bone)
  • Significant retraction of the tendons (usually more than 2 cm)
  • Persistent weakness, pain, or loss of function despite conservative treatment
  • High functional demands (e.g., athletes or active individuals)


Early surgical repair (within a few weeks of injury) often leads to better outcomes compared to delayed treatment, as it reduces the risk of tendon retraction and scar tissue formation.

What happens during a proximal hamstring repair?

The surgery generally takes 1.5 to 2 hours and will require an overnight hospital stay.

  • Incision: A horizontal or vertical incision is made in the lower buttock to access the torn tendons.
  • Identification of the injury: The retracted tendons are located and mobilised.
  • Reattachment: The tendons are securely reattached to the ischial tuberosity using strong sutures and suture anchors drilled into the bone.
  • Closure: The incision is closed in layers, and a sterile dressing is applied.

What are the risks of surgery?

As with any surgery, there are potential risks, including:

  • Infection
  • Nerve irritation, especially the sciatic nerve
  • Blood clots (DVT)
  • Incomplete healing or re-tear
  • Persistent weakness or tightness
  • Scar tissue formation
