OPERATIVE TECHNIQUE IN VASCULARIZED AUTOG RAFTS AND ALLOGRAFTS OF THEKNEE USING A CANINE MODEL

Experimental transplantation of vascularized canine knee joints has so far been associated with high complication rates in both auto- and al lografts. We have now compared 4 autografts and 4 allografts that were successfully performed at our institution. This report details our su rgical technique. Stable internal fixation enabling immediate postoper ative weight bearing, microsurgical end-to-end anastomoses of poplitea l artery and vein and postoperative control of immunosuppression in tr ansplanted animals are crucial. Thus, an interdisciplinary approach of experts in microsurgery, orthopedic and trauma surgery and immunologi sts appears to be a prerequisite for successful joint transplantation.
