Abstract: Purpose To evaluate midterm clinical outcomes of hip arthroscopy for femoroacetabular impingement syndrome (FAIS) in patients with inflammatory joint diseases (IJD) compared to a matched control group without IJD. Methods Data were prospectively collected on all hip arthroscopies performed between February 2008 and December 2018 at a single center. Patients diagnosed with IJD undergoing primary hip arthroscopy for FAIS with labral tears were included. Exclusion criteria were prior ipsilateral hip conditions (except IJD), hip dysplasia (lateral center‐edge angle <18°), and Tönnis grade >1. Patients with a minimum 5‐year follow‐up were matched 1:3 to controls based on age, sex, body mass index, and Tönnis grade. Patient‐reported outcomes (PROs), rates of achieving clinically relevant thresholds, and secondary procedures were compared between groups. Results A total of 27 hips (23 patients) with IJD were matched to 81 hips (79 patients) in the control group. At a minimum 5‐year follow‐up, both groups showed significant improvement in all PROs. However, the IJD group had lower postoperative PRO scores and fewer patients meeting patient acceptable symptom state for modified Harris Hip Score and Non‐Arthritic Hip Score (29.6% vs 61.7% and 40.7% vs 64.2%). The IJD group had significantly higher odds of requiring a second hip surgery (odds ratio, 3.57; 95% confidence interval, 1.04‐12.23; P = .042) and lower odds of maintaining arthroplasty‐free survivorship (odds ratio, 0.14; 95% confidence interval, 0.04‐0.56; P = .003). Conclusions Patients with IJD undergoing hip arthroscopy for FAIS experience significant improvement in PROs at midterm follow‐up. However, they achieve clinically significant thresholds less frequently, exhibit increased revision arthroscopy rates, and have higher rates of conversion to total hip arthroplasty compared to the control group. Level of Evidence Level III, retrospective comparative case series.
