A cross-sectional study including 184 athletes Lasse Ishøi, Kristian Thorborg, Otto Kraemer, Per Hölmich Sports Orthopedic Research Center – Copenhagen (SORC-C), Department of Orthopedic Surgery , Copenhagen University Hospital, Amager-Hvidovre, Denmark Background: Following hip arthroscopy for femoroacetabular impingement syndrome (FAIS) <20% of athletes return to optimal sport performance. However, it is unknown if specific athletic movements are important for reach- ing optimal sport performance. Purpose / Aim of Study: This study aimed to compare self-reported problems in athletic movements between athletes reporting optimal sport performance and impaired performance following hip arthroscopy for FAIS. Materials andMethods: Subjects were identified in the Danish Hip Arthroscopy Registry, and invited to answer 1) a return to sport questionnaire investigat- ing self- reported sport performance and 2) the Copenhagen Hip and Groin Outcome Score (HAGOS) sport subscale investigating problems in athletic movements. Subjects were dichotomized based on self-reported sport per- formance (optimal performance vs. impaired performance). The proportion of athletes reporting no problems (none; mild) and problems (moderate; severe; extreme) on HAGOS sport subscale questions were compared between groups. Findings / Results: 184 athletes were included. 31 athletes (16.8%) reported optimal sport performance, whereas 153 athletes (83.2%) reported impaired sport performance. The minority (<20%) of those who reported optimal sport performance had problems in athletic movements. Contrary, subjects who re- ported impaired performance often had problems with high- load athletic move- ments such as running fast (64%), kicking/skating (58%), explosive movements (60%), and outer hip positions (70%). Conclusions: Most athletes with impaired performance following hip arthros- copy for femoroacetabular impingement syndrome have problems in high-load activities such as running fast, kicking/skating, explosive movements, and outer hip positions. Such information may guide future focus on post-operative reha- bilitation for femoroacetabular impingement. 186.
