Hypermobility has been suggested as a possible cause of GTPS. Purpose / Aim of Study: The purpose of this study was to report the preva- lence of hypermobility and to investigate its impact on hip-related function and awareness in patients with GTPS. Materials and Methods: This cross-sectional study was based on a cohort of patients diagnosed with GTPS in the 2013-2015 period. Hypermobility was investigated with the Beighton Score and defined by a cut-off score ≥ 5. Data on patients‘ current hip function and awareness were collected with the ques- tionnaires the Copenhagen Hip and Groin Outcome Score and the Forgotten Joint Score. Findings / Results: A total of 612 patients with GTPS were identified based on the diagnosis system; out of those, 390 patients were assessed for eligibility, and 145 (37%) were included. The prevalence of hypermobility within this co- hort was estimated to be 11% (95% confidence interval (CI): 3-26%) for males and 25% (95% CI: 17-34%) for females. No significant association was found between hypermobility and self- reported hip function and awareness. Conclusions: The prevalence of hypermobility in patients with GTPS was high, but the prevalence of hypermobility did not influence hip function and aware- ness. The results were based on a very low response rate and should be inter- preted with this in mind. 167.
