Abstract
BACKGROUND: There is a paucity of literature analyzing data for return to sport (RTS) and return to work (RTW) in the setting of direct anterior approach (DAA) total hip arthroplasty (THA). OBJECTIVE: The aims of this systematic review are to identify existing literature and to aggregate rates of RTS/RTW following DAA THA in a meta-analysis. METHODS: A query of major databases yielded 1819 initial studies. A random-effects model approach was implemented for meta-analysis. Moderator effects were assessed with respect to patient demographics and functional outcomes. RESULTS: Five studies reporting RTS after DAA THA were identified, representing a total of 204 patients with a mean age of 60.2±7.5 years and mean follow up of 31.8±9.5 months. Pooled rate of RTS was 76%(95% confidence interval [CI], 63%-86%;range 58%-100%). Pooled rate of return to the same sport was 77%(95%CI, 64%-86%;range of 62%-100%). Pooled rate of RTS to the same intensity was 58%(95%CI, 48%-68%;range of 41%-68%). Meta-regression demonstrated no significant correlations between independent variables and RTS characteristics. Three studies reported RTW rates. Rates of RTW within 3-months were 30%, 45%, and 60%. One study reported rate of RTW of 79% at 6-months and 87% at 12-months. One study demonstrated a mean time to RTW of 38±24.8 days. CONCLUSION: Pooled rate of RTS is satisfactory following DAA THA and are comparable to rates of RTS aggregated without delineating surgical approach. Data supporting RTW rates following DAA THA limited, and thus more primary studies are needed to establish if this approach confers an advantage of faster RTS/RTW.
