The purpose of this study was to determine if there is a difference in hip survivorship rates and patient-reported outcomes (PROs) at a 5-year follow-up after arthroscopic treatment of femoroacetabular impingement syndrome (FAIS) between patients with versus without systemic inflammatory diseases (SIDs). A retrospective single-surgeon matched cohort study of FAIS patients who underwent hip arthroscopy and had a minimum of a 5-year follow-up was conducted. Subjects with SIDs were matched at a ratio of 2:3 of age and body mass index (BMI) with respect to controls without SIDs. Subjects completed the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS) prior to surgery and at a 2-year and 5-year follow-up. Survival distributions for time to reoperation and to total hip arthroplasty (THA) were compared between groups using the log-rank test. Fifteen subjects with SIDs (mean age 41.5 years) were matched with twenty-five controls (41.8 years). There were no significant differences in reoperation rates (SIDs 27% vs. controls 20%, p = 0.71) or THA conversion rates (SIDs 7% vs. controls 12%, p = 1.00) at the 5-year follow-up, nor were there differences in survival distributions for reoperations (p = 0.72) or THAs (p = 0.55). There were no significant differences in postoperative mHHS (SIDs 79.3 vs. controls 88.5, p = 0.09) or NAHS (SIDs 82.7 vs. controls 89.3, p = 0.77) by the 5-year follow-up. At the 5-year follow-up, FAIS patients with comorbid SIDs experienced a significant clinical improvement from hip arthroscopy that is comparable to that of FAIS patients without SIDs.
