Complete proximal hamstring tendon avulsions from the ischial tuberosity, though infrequent, are the most severe type of hamstring muscle injury in the field of sport medicine.These serious injuries are commonly associated with a delayed or even misdiagnosis, despite obvious clinical findings.The published literature favours surgical repair even though the studies represent lower levels of evidence.Non-surgical treatment is a viable option for lower physical demand patients.This state-of-the-art article reviews the relevant anatomy, the clinical assessment including specific physical examination signs and diagnostic testing in patients suspected of a proximal hamstring avulsion.Up-to-date evidence is reviewed to address surgical and non-surgical treatment options and outcome assessment.The authors provide a detailed description of what would be considered the current worldwide standard of care; an open, suture-anchor-based repair of the avulsed tendon complex (semitendinosus, long head of biceps femoris and semimembranosus) securely to the ischial tuberosity.Also included are surgical tips and tricks, with advice on postsurgical management and rehabilitation.Future perspectives should involve higher quality, prospective research to better define the indications for surgery, evaluate the emerging role of endoscopic repair and disclose complications along with measuring patient-reported outcomes.
