Editorial Commentary: Postoperative Alpha Angle and Return to Sport: One Piece of the Puzzle

Return-to-sport rates following arthroscopic treatment of femoroacetabular impingement are high; however, the predictors of failure to return to sport must be elucidated. Recent data suggest that the postoperative alpha angle may be a significant predictor of return to sport in athletes, despite the fact that the role of radiographic measurements on postoperative outcomes is debated in the literature. Nonetheless, it is incumbent on surgeons to fully understand the unique biomechanics of the hip in each sport and consider each patient’s unique anatomy when undertaking cam resection. Recreation of the motion at-risk during a careful intraoperative dynamic examination is imperative to ensure that all areas of impingement have been eradicated while attentively avoiding over-resection. While the postoperative alpha angle is an important metric for surgeons to keep in mind, it may only represent one piece of the puzzle.
