Abstract

Further high level studies are necessary to prove their usefulness. Newer methods which may hold promise are arthroscopic collagen sheath wrapping of complex tears with bone marrow aspirate injected under it, and a chitosan PRP composite implant. In some instances meniscus repair may not be feasible, and patients may have segmental, subtotal, or total loss of menisci. In such situations, meniscal substitution in the form of allograft transplant for subtotal or total meniscal loss, and artificial meniscal scaffolds for segmental defects are a viable option.
