Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Reconstructive Surgery

Background:

  • Chronic, retracted proximal hamstring ruptures cause significant pain and disability.
  • Surgical intervention is indicated for symptomatic patients unable to undergo primary repair.
  • Allograft augmentation presents a viable surgical option with favorable clinical outcomes.

Purpose of the Study:

  • To evaluate the efficacy of allograft augmentation for chronic proximal hamstring ruptures.
  • To compare outcomes of allograft reconstruction with primary repair and nonoperative management.

Main Methods:

  • Surgical technique involves an L-shaped incision, sciatic nerve identification, and allograft incorporation.
  • Achilles tendon allograft is fixed to the ischial tuberosity using suture anchors.
  • Postoperative management includes a hip brace locked in extension.

Main Results:

  • Studies show allograft reconstruction yields outcomes comparable to acute primary repair for delayed proximal hamstring repair.
  • Patient-reported outcomes were not significantly different between acute repair, chronic repair, and allograft reconstruction groups.
  • Allograft augmentation demonstrated increased functional outcomes compared to nonoperative management.

Conclusions:

  • Allograft augmentation is a favorable surgical option for symptomatic patients with chronic, retracted proximal hamstring ruptures.
  • This technique provides improved functional outcomes versus nonoperative management.
  • Outcomes are comparable to primary repair methods.
