PRE- AND POST-OPERATIVE SELF-REPORTED FUNCTION AND QUALITY OF LIFE IN WOMEN WITH AND WITHOUT GENERALIZED JOINT LAXITY UNDERGOING HIP ARTHROSCOPY FOR FEMOROACETABULAR IMPINGEMENT.
BACKGROUND
Generalized joint laxity is more prevalent in women than men and may lead to poorer post-operative outcomes in select orthopedic populations. There are no studies examining peri-operative function in patients with generalized joint laxity (GJL) and femoroacetabular impingement (FAI).


OBJECTIVE
The purpose of this study was to determine the difference in perceived function and quality of life as measured by the Hip Outcome Score ADL subscale (HOS-ADL), International Hip Outcomes Tool (iHOT-33) and the Short Form 12-Item Health Survey (SF-12) in women with and without GJL prior to and six months after undergoing hip arthroscopy for FAI.


METHODS
Cohort Study.


METHODS
Peri-operative data were collected from women with FAI from November 2011-September 2014. Lax subjects were women with laxity scores ≥4/9 on the Beighton and Horan Joint Mobility Index; Nonlax subjects were women with laxity scores <4/9. Functional outcomes were evaluated using the HOS-ADL, iHOT-33, PCS-12, and the MCS-12 pre-operatively and at 6 months post-operatively. Change scores (post-score - pre-score) were calculated for each outcome measure and compared between groups, along with pre-operative and post-operative means, using Mann-Whitney U tests.


RESULTS
166 women met the inclusion criteria: Nonlax (n = 131), Lax (n = 35). There were no statistically significant differences between groups in pre-operative functional outcomes (all p > .05). Additionally, there were no statistically significant differences between groups in post-operative means or change scores, respectively, for HOS-ADL (p = .696, .358), iHOT-33 (p = .550, .705), PCS-12 (p = .713, .191), and MCS-12 (p = .751, .082). Laxity score was not associated with any post-operative functional outcome score or change score (all p > .05).


CONCLUSIONS
Women with and without generalized joint laxity do not appear to report differences in hip function in the 6-month peri-operative period before and after hip arthroscopy for FAI.
