At mid- to long-term follow-up after proximal hamstring tendon avulsion; there was greater fatty infiltration, muscle atrophy and strength deficit in the hamstring muscles of the injured leg than in the uninjured leg

Abstract

Key points Proximal hamstring avulsion results in muscle atrophy and fatty infiltration. The muscle degeneration after proximal hamstring avulsion is correlated to reduction in muscle strength. The muscle degeneration and its correlation to reduction in muscle strength hold true also for operatively treated patients.
