Allograft Reconstruction of the Knee-Methods and Outcomes

Although allograft usage has decreased over the past three decades in favor of segmental metal implants, they still have an important role in the reconstruction of large osteochondral defects following tumor resection. The decline of allografts in limb salvage is multifactorial and includes limited availability, technical difficulty, increased rates of infection and fracture, and unpredictable results. There are circumstances where allograft transplantation is useful around the knee resulting in improved function, bone and joint preservation, and acceptable long-term outcomes.
