Abstract
Background: Anterior inferior iliac spine (AIIS) impingement has been increasingly recognized as a source of extra-articular impingement and hip pain. However, no aggregate data analysis of patient outcomes after AIIS decompression has been performed.
Purpose: To evaluate outcomes after arthroscopic AIIS decompression.
Study Design: Meta-analysis; Level of evidence, 4.
Methods: A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were queried for all Englishlanguage studies reporting outcomes of arthroscopic AIIS decompression performed in isolation or in conjunction with hip impingement correction surgery. After screening, 10 articles were included. The indications for AIIS decompression were recorded, and weighted mean improvements in patient-reported outcome (PRO) scores, complication rates, and revision rates were calculated.
Results: A total of 547 patients (311 women; 57%) were identified, with a total of 620 operative hips. The mean age was 28.42 +/- 5.6 years, and the mean follow-up was 25.22 +/- 11.1 months. A total of 529 hips (85%) underwent AIIS decompression, 530 hips (85%) underwent femoral osteochondroplasty, and 458 hips (74%) underwent labral repair. Of the patients, 13% underwent bilateral AIIS decompression. The mean modified Harris Hip Score improved from 61.3 +/- 6.9 to 88.7 +/- 4.7 postoperatively (change, 27.4 +/- 5.7 points; P < .001), the Hip Outcome Score-Activities of Daily Living improved from 67.2 +/- 10.6 to 91.1 +/- 3.2 postoperatively (change, 24.0 +/- 8.0 points; P =.001), and the Hip Outcome Score-Sports Specific Subscale improved from 36.8 +/- 19.2 to 82.8 +/- 3.8 postoperatively (change, 46.0 +/- 18.2 points; P =.002). The pooled risk of postoperative complications was 1.1% (95% CI, 0.1%-2.1%), and the pooled risk of needing revision surgery was 1.0% (95% CI, 0.1%-2.0%). No complication was directly attributed to the AIIS decompression portion of the procedure.
Conclusion: PROs improved significantly after hip arthroscopy with AIIS decompression, with a low risk of postoperative complications and subsequent revision surgeries. Failure to identify extra-articular sources of hip pain in outcomes of femoroacetabular impingement syndrome, including from the AIIS, could lead to poorer outcomes and future revision surgery.
