      A meta-analysis is a comprehensive systematic review in which statistical analyses are used to combine the results of two or more homogeneous clinical trials1-4. In the paradigm of evidence-based orthopaedics, meta-analysis can be an invaluable tool to increase study power and improve precision when study results are combined appropriately5. Evidence from a meta-analysis, however, is highly dependent on the quality of the primary studies included and on the overall methodological rigor6. Meta-analyses have impacted clinical practice, paved the way for clinical practice guidelines and health policies, and guided subsequent research6,7.
