Hamstring Injuries Surgical Treatment

When two or three of the tendons tear completely away from the sit bone and retract, the muscle loses its anchor, and non-operative treatment in an active patient tends to leave lasting weakness, cramping, difficulty sitting, and an inability to sprint. Repair restores the anatomy and the tension of the muscle group.

Timing is important. Repairs performed within the first several weeks are considerably more straightforward than those performed later, because the tendons have not yet retracted far or become encased in scar tissue near the sciatic nerve. A delayed diagnosis is one of the more common reasons a simple repair becomes a complex one, which is why a suspected avulsion deserves prompt evaluation and an MRI rather than a period of watchful waiting.

Chronic avulsion may still be repaired when symptoms warrant it, though the operation is more involved and recovery is longer.

These are considered for surgery only after a well-executed non-operative program has failed over a period of months.

When this condition remains symptomatic despite therapy and injections, it may also be addressed surgically.

Every surgical plan begins with imaging. MRI defines how many tendons are involved, how far they have retracted from the sit bone, the quality of the remaining tissue, and the relationship of the injury to the sciatic nerve. These findings determine the approach, whether graft tissue may be needed, and what the recovery will look like, and Dr. Rynecki Baker reviews them with each patient before surgery so that expectations are set accurately from the beginning.

Proximal hamstring repair reattaches the torn tendons to their origin on the ischial tuberosity. The patient is positioned face down under anesthesia, and the tendons are identified and mobilized back to the bone. The footprint on the ischium is prepared, and the tendons are secured with suture anchors placed into the bone, restoring both the position and the tension of the hamstring origin.

Because the sciatic nerve lies immediately adjacent to this region, it is identified and protected throughout. In chronic cases the nerve is frequently surrounded by scar tissue, and carefully releasing it, a step known as neurolysis, is an important part of the operation and often a significant source of symptom relief in its own right.

In chronic cases where the tendons cannot be brought back to the bone because they have shortened and scarred, graft tissue may be used to bridge the gap and restore continuity.

When narrowing of the space between the ischium and the lesser trochanter is the source of persistent symptoms and non-operative treatment has not succeeded, that space can be decompressed surgical. This relieves the compression on the muscle passing through the corridor. Because this condition is frequently unrecognized, patients who reach this point have often been treated for hamstring tendinitis or sciatica for a long period beforehand.

Recovery from a proximal hamstring repair is deliberate, because the repair must be protected while tendon heals to bone. Early on, patients use crutches and often a brace that limits the combination of hip flexion and knee extension, since that position places direct tension across the repair. Weight-bearing is advanced gradually according to the security of the repair and the chronicity of the injury.

Range of motion progresses over the first six to eight weeks, and active hamstring strengthening is deliberately delayed until the tendon has begun to heal to the bone. Strengthening then advances progressively over the following months, moving from isometric work to controlled eccentric loading and eventually to running. Return to sprinting and sport generally falls between six and nine months, guided by objective strength testing and functional assessment rather than by the calendar alone.

Patients should understand that this is a long recovery, and that the early restrictions exist for a reason. The most common avoidable complication after this operation is a repair placed under tension too early.

Surgery around the hamstring origin is technically demanding and takes place directly alongside the sciatic nerve, and outcomes are closely tied to accurate diagnosis, appropriate patient selection, and the experience of the surgeon. Dr. Rynecki Baker’s fellowship training at both NYU and Hospital for Special Surgery, combined with her focus on hip preservation and her published research in sports medicine, means patients are treated by a specialist who operates on this region regularly and who is equally willing to say when an operation is not needed.
