Graft Selection in ACL Reconstruction
Different types of grafts have been used to reconstruct the torn ACL. Generally, these can be divided into autogenous, allogenous, and xenogenous grafts based on the species of the donor. Tissue-engineered grafts are the fourth new type that can be made up of any of the previously mentioned grafts, from synthetic products or their combinations. Tissue-engineered grafts overlap with the xenografts but possess more options and can be divided into three categories, including biologic, synthetic, or hybrid grafts, based on the origin of their material. The advantages and disadvantages of each graft type are briefly highlighted in Table 1.
