Background: Chronic, retracted proximal hamstring ruptures are a challenging problem and can be a significant cause of pain and disability if left untreated. Allograft augmentation is a viable surgical option with good clinical outcomes. Indications: Indications are symptomatic patients with chronic hamstring ruptures unable to be primarily repaired. Patients typically present with pain, instability, or lack of push of strength. Technique Description: An L-shaped extensile incision is made at the level of the gluteal crease. The gluteus maximus is retracted proximally. The sciatic nerve is identified, neurolysed, and tagged. Following the release of adhesions of the native tendon and confirmation of the inability to complete a primary repair, the Achilles tendon allograft is prepared. The allograft is incorporated with the native tendon and the subsequent hamstring construct is fixed and reduced to the ischial tuberosity with suture anchors. After copious irrigation, the incision is closed with Monocryl and Dermabond (Johnson and Johnson) and a sterile dressing is applied. The patient is placed in a hip brace locked in extension. Results: In a study by Rust et al, examining 72 patients with proximal hamstring ruptures, patients who underwent allograft reconstruction reported activities of daily living and postoperative sports activity equal to those of chronic repair, and inferior to those of acute repair. However, there were no significant differences between groups for patient-reported outcomes among acute and chronic repairs and allograft reconstruction. Moreover, a systematic review, by Van Der Made et al, published in the American Journal of Sports Medicine , included 13 studies that found that Achilles allograft repair for delayed proximal hamstring repair results in outcomes comparable to acute primary repair. Discussion/Conclusion: Although the literature on chronic proximal hamstring repair is fairly limited, studies have shown that proximal hamstring repair with allograft augmentation can be favorable in symptomatic patients. Allograft augmentation for chronic, retracted proximal hamstring ruptures provides increased functional outcomes in comparison with nonoperative management.
