BACKGROUND: Repair of torn pectoralis major tendons is generally considered superior to nonoperative management, but there is a paucity of comparative data to demonstrate ideal repair timing and fixation methods. PURPOSE/HYPOTHESIS: The purpose was to compare the outcomes between acute and chronic repair and among the various methods of fixation (transosseous tunnels, cortical buttons, suture anchors, screws with washers, and direct repair). It was hypothesized that acute repair would have superior outcomes and there would be similar outcomes among the various methods of fixation. STUDY DESIGN: Meta-analysis. METHODS: In accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic review of the literature was completed through MEDLINE, SPORTDiscus, CINAHL, Cochrane, Embase, and Web of Science databases. English-language studies were included with a minimum of 6 months' mean follow-up and 5 cases per study. MINORS (Methodological Index for Nonrandomized Studies) was utilized to assess the quality of the existing literature. Analysis of mechanisms of injury and meta-analysis of pooled outcomes were completed. Pooled effect sizes were calculated from random effects models. Continuous variables were assessed via mixed model analysis, with the individual study designated as a random effect and the desired treatment for comparison as a fixed effect. Bivariate frequency data were transformed through Freeman-Tukey log-linear transformation for variance stabilization and then assessed through a mixed model with a study-level random effect and subsequently back-transformed. Significance was set at P < .05. RESULTS: Twenty articles with 384 injuries met the inclusion criteria for comparison. All patients were male, with 61.9% of injuries occurring during weight training, at a mean age of 31.53 years, and with a mean follow-up of 30.12 months. Included studies scored a mean (SD) 15.53 ± 4.26 (range, 7.0-23.3) by MINORS criteria. Acute repair was significantly superior to chronic repair, with a relative improvement of functional outcome by 0.85 (P = .004) and satisfaction with cosmesis by 20.50% (P = .003). There was a trend toward acute repair having a higher proportion of patients who were pain-free (34.47%, P = .064). There were no significant differences among the methods of fixation for repair. CONCLUSION: Acute repair of pectoralis major tendon tears resulted in significantly superior functional outcomes and cosmesis satisfaction with a trend toward a higher proportion of patients who were pain-free. There were no significant differences among the methods of fixation for repair.
