Fig. 2

A forest plot diagram showing the incidence of dislocation. Seven studies assessed the incidence of dislocation. Heterogeneity test (I² =0%) indicated that there is statistical homogeneity among the studies, so the fixed-effect model was used to analyze. The results of the meta-analysis showed that there was a significant difference in the incidence of postoperative dislocation between transosseous repair group and transmuscular repair group (OR 0.4, 95% CI 0.22–0.73, P = 0.003, I² = 0%)
