| Abstract: | Fresh allogeneic diaphyseal bone segments were transplanted into 12 dogs. We attempted to improve the immunogenity and incorporation of the bone segments through "graft manipulation" with and without immunosuppression. Through clinical and radiological study during the 20-week experimental period, we observed transplant healing with differing structural phenomena. After autologous knee joint replantation in 4 dogs and allogeneic transplantation in 2 dogs (with and without revascularization and immunomodulation with Cyclosporin A) we present a canine model to investigate all open questions about the transplantation of allogeneic, fresh joints (i.e. transplant biology, immunology, and vitality). |
