Effect of cam resection depth on clinical outcomes after primary hip arthroscopy.

Background: The amount of resection or the starting point of the resection on the femoral head for cam lesions in femoroacetabular impingement (FAI) is controversial.

Aim: The purpose of this study was to study the effect of postoperative resection depth, and resection arc ratio of cam lesion on the frequency of achieving substantial clinical benefit (SCB), patient acceptable state (PASS) in modified Harris Hip Score (mHHS) and Hip Outcome Score Activity of Daily Living (HOS), 2 years postoperatively.

Patients And Methods: All patients who underwent first-time hip arthroscopy for FAI with a 2-year follow-up were included in this study.
