Proximal Hamstring Repair After a Tendon Tears Off the Bone
When does a torn hamstring need surgery?
Proximal hamstring repair is a surgery that reattaches hamstring tendons torn off the sitting bone (ischial tuberosity) at the bottom of the buttock. Surgery is usually recommended when all three tendons tear, or two tear and pull back more than about 2 centimeters, and is most reliable when done within a few weeks of injury.
Most hamstring strains heal with time and rehab. A different injury happens when the tendons tear completely off the sitting bone, often during waterskiing, a slip with the leg flying forward, sprinting or a sudden split. People describe a pop high in the back of the thigh, heavy bruising and pain sitting. These avulsions often need a timely repair, so a quick exam and MRI matter.

Is Proximal Hamstring Repair right for you?
Usually a good fit if
- All three hamstring tendons torn from the sitting bone
- Two tendons torn with more than about 2 centimeters of retraction
- Active adults who want to return to running, sport or heavy work
- Partial tears that still cause pain and weakness after about 3 months of rehab
- An injury less than 4 to 6 weeks old, which allows a more direct repair
Another option may be better if
- Muscle strains in the belly of the hamstring, which heal without surgery
- Single-tendon tears with little retraction in most less active patients
- Patients who cannot follow the brace and crutch restrictions
What happens, step by step
Prompt evaluation
Dr. Stride looks for bruising down the thigh, a palpable gap near the sitting bone and weakness bending the knee. An MRI shows how many tendons are torn and how far they have pulled back. Our team tries to see these injuries within days, since timing affects the repair.
Reattaching the tendons
Through an incision in the buttock crease, the sciatic nerve is identified and protected, and the tendons are pulled back to the bone and secured with suture anchors. Smaller tears are sometimes repaired endoscopically.
Protecting the repair
Many patients wear a knee or hip brace that limits stretch on the hamstring. You go home the same day in most cases, with crutches and a rehab plan.
Typical recovery timeline
Crutches with touch-down weight bearing and a brace that keeps the knee bent to keep tension off the repair. Sitting on a cushion helps.
Weight bearing increases, crutches are weaned and gentle hamstring activation begins in physical therapy.
Strength training, stationary bike and walking for exercise. Desk work has usually resumed earlier.
Jogging, then sport-specific drills, once strength is close to the other leg.
Return to sprinting, waterskiing and competitive sport for many patients, based on testing.
Timelines are typical ranges. Your plan depends on your hip, your health and what was done in surgery.

“A complete hamstring avulsion is one injury where waiting can work against you. The tendons scar down and pull farther away each week, and the sciatic nerve gets caught up in that scar. If you felt a pop and see a big bruise in the back of your thigh, come see me this week.”

Frequently asked questions
How do you know if you tore your hamstring off the bone?
A pop at the top of the back of the thigh, heavy bruising spreading down the leg, pain when sitting and weakness bending the knee all point toward a proximal hamstring tear. An MRI confirms how many tendons are torn and how far they have retracted.
How soon should a proximal hamstring tear be repaired?
Repairs are generally easier and more reliable when done within about 4 to 6 weeks of injury. Later repairs are possible but may be more complex, sometimes requiring a graft.
What is recovery like after hamstring repair surgery?
Expect about 6 weeks on crutches, often with a brace, followed by progressive strengthening. Most people return to running and sports in about 4 to 9 months, depending on the tear and the sport.
Can a proximal hamstring tear heal without surgery?
Partial tears and single-tendon tears often improve with rehab. Complete tears of multiple tendons with significant retraction tend to leave lasting weakness and pain sitting when treated without surgery, especially in active people.
