A new fibrinogen system, consisting of highly concentrated fibrinogen and thrombin, is going to be applied in many clinical fields. Especially in injuries of the cartilagenous joint surface as chondral or osteochondral fractures, replantation of the fragments must be considered mandarory in order to preserve joint congruence and to prevent further destruction of the articular cartilage. The authors have an encouraging results by using this fibrin adhesive system (F.A.S.) in the experimental works.
