Long-term Outcomes of Partial Proximal Hamstring Avulsion Repair: Mean 10-Year Follow-up

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Reconstructive Surgery

Background:

• Surgical repair of partial proximal hamstring avulsions improves short- and midterm outcomes.
• Long-term results and the impact of tendon involvement on outcomes remain unclear.

Purpose of the Study:

• To evaluate long-term hamstring function and patient satisfaction after surgical repair of partial proximal hamstring avulsions.
• To compare outcomes between isolated and combined tendon involvement.

Main Methods:

• A case series (Level of evidence, 4) included patients with surgically repaired proximal hamstring avulsions.
• Patient-reported outcomes included the Lower Extremity Functional Score (LEFS), Marx Activity Rating Scale, and custom scores.
• Long-term outcomes were compared to midterm outcomes, and isolated vs. combined tendon injuries were analyzed.

Main Results:

• At a mean 10.1-year follow-up (53 patients), high satisfaction (91%) and return to sport rates (95%) were observed.
• Functional scores (LEFS, Marx) remained high, with no significant differences between long-term and midterm follow-up, except for slight decreases in Marx scores.
• Outcomes were similar for isolated versus combined tendon involvement, with a low complication rate (1.7% revision).

Conclusions:

• Surgical repair of partial proximal hamstring avulsions yields successful long-term outcomes and high return-to-activity rates.
• Outcomes are stable over time and do not differ based on the extent of tendon involvement.
• The procedure demonstrates a favorable safety profile with low complication rates.
