Abstract
PURPOSE: To describe the prevalence of abnormal sleep quality in patients with femoroacetabular impingement syndrome and to determine whether arthroscopic hip preservation surgery with cam/pincer correction, labral preservation, and capsular plication can improve sleep quality postoperatively. METHODS: All patients undergoing primary hip arthroscopy for cam/pincer correction who failed nonoperative management between March 1, 2017, and July 1, 2017, were administered a validated sleep quality questionnaire-the Pittsburgh Sleep Quality Index (PSQI)-preoperatively and at 3, 6, 12, and 24 weeks postoperatively. Exclusion criteria included patients undergoing revision arthroscopy, gluteus medius repair, or a contralateral procedure during the follow-up period and those with known sleep disorders. A global (total) PSQI score >5 indicates poor sleep quality. The Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sports Specific Subscale, modified Harris Hip Score, and International Hip Outcome Tool-12 were used to assess functional outcomes. A repeated measures analysis of variance with post hoc Greenhouse-Geisser and Bonferroni corrections was conducted to determine statistically significant changes in sleep patterns. RESULTS: A total of 52 patients (94.6%) were included in the final analysis. The mean (± standard error) patient age was 37.8 ± 1.9 years, and body mass index was 27.6 ± 0.7. Preoperatively, 49 (94.2%) of patients experienced poor sleep quality, defined as a global PSQI score >5, with a mean PSQI score of 9.8 ± 0.6. At 24 weeks postoperatively, 10 (21.7%) of patients experienced poor sleep quality with a mean PSQI score of 2.2 ± 0.2. All patients had significant improvements in all hip outcome instruments at 24 weeks postoperatively (P < .001). CONCLUSIONS: Preoperatively, patients with femoroacetabular impingement syndrome have a high prevalence of sleep disturbance. These patients experience subsequent improvement in sleep disturbance after arthroscopic hip surgery early in the postoperative period. LEVEL OF EVIDENCE: Level IV, case series.
