Sex Differences in Self-Reported Hip Function Up to 2 Years After Arthroscopic Surgery for XXXX .

@entity1 @entity1743
BACKGROUND: @entity1743 ( @entity1743 ) is a significant cause of disability in young adults. Hip arthroscopic surgery restores bony congruence and improves function in the majority of @entity1 , but recent evidence indicates that @entity1 may experience worse pre- and postoperative function than @entity1 . PURPOSE/HYPOTHESIS: The purpose of this study was to identify whether self-reported hip function differed between @entity1 and @entity1 with symptomatic @entity1743 . The hypothesis was that mean self-reported hip function scores would improve after arthroscopic surgery but that @entity1 would report poorer function than @entity1 both before and up to 2 years after arthroscopic surgery. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A total of 229 @entity1 (68.4% @entity1 ; mean [  SD] age, 31.6    10.8 years; mean [  SD] body mass index, 26.8    11.9 kg/m(2)) underwent hip arthroscopic surgery for unilateral symptomatic @entity1743 . All eligible and consenting @entity1 with radiologically and clinically confirmed @entity1743 completed the International Hip Outcome Tool (iHOT-33) and the Hip Outcome Score activities of daily living subscale (HOS-ADL) before hip arthroscopic surgery and at 3, 6, 12, and 24 months after arthroscopic surgery. A linear mixed model for repeated measures was used to test for differences in self-reported hip function between @entity1 and @entity1 over the study period (P  <= .05). RESULTS: There were no significant time * sex interactions for either the HOS-ADL (P = .12) or iHOT-33 (P = .64), but both measures showed significant improvements between the preoperative time point and each of the 4 follow-up points (P < .0001); however, self-reported hip function did not improve between 6 and 24 months after arthroscopic surgery (P >=  .11). Post hoc independent t tests indicated that @entity1 reported poorer hip function than did @entity1 before surgery (P  <= .003) both on the HOS-ADL (mean    standard error of the mean [SEM], 67.4    1.9 [ @entity1 ] vs 60.5    1.3 [ @entity1 ]) and iHOT-33 (mean    SEM, 38.0    1.9 [ @entity1 ] vs 30.9    1.3 [ @entity1 ]); scores were not different between sexes at any other time point. CONCLUSION: These findings indicate improvements in self-reported hip function in @entity1 with @entity1743 , regardless of sex, until 6 months after hip arthroscopic surgery. Although @entity1 reported poorer preoperative function than did @entity1 , the differences were not significant 2 years after surgery.
