Risk Factors for Graft Failure After Meniscal Allograft Transplantation: A Systematic Review and Meta-analysis.

Background: Graft failure after meniscal allograft transplantation (MAT) may necessitate revision surgery or conversion to arthroplasty. A comprehensive understanding of the risk factors for failure after MAT of the knee may facilitate more informed shared decision-making discussions before surgery and help determine whether MAT should be performed based on patient risk.

Purpose: To perform a systematic review and meta-analysis of risk factors associated with graft failure after MAT of the knee.
