Editorial Commentary: A Call for Clarity-Standardizing Return-to-Sport Definitions Is Essential for Interpreting Hip Arthroscopy Outcomes.

Outcome reporting in sports medicine has become increasingly sophisticated, yet sophistication alone does not ensure clinical usefulness. The value, or utility, of an outcome measure lies in its ability to inform patient expectations, shared decision-making, and treatment selection. This limitation is particularly evident in the reporting of return-to-sport (RTS) outcomes. Differences in RTS definitions can yield substantially different reported success rates without reflecting true differences in surgical effectiveness. For example, defining RTS as return to preinjury competitive level produces markedly lower rates than broader definitions based on any attempted participation. The critical issue is not which definition yields higher RTS rates but which provides greater decision-making utility for athletes. Because RTS is highly susceptible to external, nonmedical influences, standardized definitions and careful interpretation are essential for meaningful comparison and clinical relevance.
