To assess the diagnostic value of intra-articular anesthetic hip injection in patients with hip pain atypical for osteoarthritis (OA), literature was searched. Included were studies assessing the diagnostic value of anesthetic hip injections in differentiating between pain caused by OA or another source. Pooled estimates of sensitivity and specificity with 95% confidence intervals (CI) were calculated. Of the 1387 potentially eligible articles, nine case series with high risk of bias could be included. The pooled sensitivity was 0.97 (95% CI 0.87, 0.99). Specificity was 0.91 (95% CI 0.83, 0.95). For clinical practice, no recommendation can be made regarding the use of hip injections for diagnosing hip OA. High quality, accurately reported studies are needed to provide better evidence on the diagnostic role of hip injection.
