Functional Outcomes, Complications, and Failure Rates in Workers’ Compensation Patients Following Hip Arthroscopic Repair: A Systematic Review

Abstract

Background: Studies on the feasibility of hip arthroscopy in workers’ compensation (WC) patients have been largely inconsistent or limited by study design, necessitating the need for a systematic review. Purpose: We sought to systematically compare clinically significant differences between WC patients and their counterparts in relation to (1) functional outcomes, (2) complications, and (3) failure rates after hip arthroscopy. Methods: We searched MEDLINE, EMBASE, and PubMed databases for studies published between January 1996 and February 2021. In combination with “AND” or “OR” Boolean operators, the following keywords were implemented: “hip arthroscopy,” “workers’ compensation,” “outcomes,” “complications,” “revision,” and “failure rates.” Two reviewers screened eligible studies, evaluated methodological quality, and abstracted data. Results: In the 13 studies pooled, comprising 1874 patients, 276 (14.7%) patients received WC benefits. Twelve studies utilized functional outcomes, 2 studies assessed pain, and 3 studies evaluated satisfaction. Despite scoring lower in these measures preoperatively, WC patients demonstrated significant improvements after hip arthroscopy. Three studies linked compensation with marginally inferior functional scores, but this association was not significant at longer follow-up. Seven studies examined complication incidence, and 6 studies addressed failure rates, with all reporting no significant differences in rates of complications, secondary arthroscopies, or conversion to total hip arthroplasty. Conclusions: The findings of this systematic review suggest that hip arthroscopy offers clinically significant benefits, regardless of WC status. Postoperative results in WC patients, including functional scores, pain, satisfaction, complications, and failure rates, were favorable, and the degree of improvement was at least comparable with their counterparts. Further studies should consider prospective study designs with larger cohorts and extended follow-up.
