‘Suture-induced tear’ after human meniscal allograft transplantation

Meniscal allograft transplantation (MAT) is generally associated with good outcomes. However, the likelihood of a successful outcome is reduced by various complications, and a meniscal tear is one of the most common of these after MAT. Meniscal tears usually occur at the periphery of the meniscal allografts at the capsular junction or the posterior horn, and biomechanical factors, such as high contact stress areas, are possible causing mechanism. We encountered three unusual cases with multiple radial or horizontal tears possibly induced by the suture materials used for meniscus allograft fixation.
