Endoscopic-Assisted Anatomic Reconstruction of Chronic Proximal Hamstring Avulsion With Achilles Allograft.

Hamstring injuries commonly occur at the musculotendinous junction; however, they can occur as proximal avulsion injuries. A lack of recognition can lead to proximal hamstring injuries being frequently misdiagnosed, resulting in delayed treatment. Chronic proximal hamstring tears are often retracted and scarred to the surrounding soft tissues.

Arthroscopic classification of intra-articular hip pathology demonstrates at best moderate interrater reliability.

Purpose: The purpose of this study was to report several novel classification systems for intra-articular lesions observed during hip arthroscopy, and to quantify the interrater reliability of both these novel systems and existing classifications of intra-articular lesions when tested by a group of high-volume hip arthroscopists.

Methods: Five hip arthroscopists deliberated over shortcomings in current classification systems and developed several novel grading systems with particular effort made to capture factors important to the treatment and outcomes of hip arthroscopy for labral injury. A video learning module describing the classifications was then developed from the video archive of surgeries performed by the senior author and reviewed by study participants.
