AIM: The benefits of postoperative wound drainage in @entity1 with @entity348 ( @entity348 ) with regards to mobilisation and wound healing were studied. We wanted to determine the efficacy of an autologous blood retransfusion system. METHOD: 150 @entity1 with @entity348 were divided into three groups of 50 @entity1 : A) three wound drainages with an autotransfusion system and suction; B) no wound drainage; C) one intraarticular wound drainage without suction. Hemoglobin values, blood transfusion requirements, @entity190 , postoperative range of motion, Insall knee score and rate of complications were observed and recorded. All @entity1 were operated without tourniquets for lower @entity190 . RESULTS: In the group of @entity1 with wound drainage and a retransfusion system the requirement of postoperative additional blood transfusion was not significantly less than in the group without wound drainage. Group A had the highest @entity190 of all. The group without wound drainage had more @entity1410 and @entity532 . Best results were observed within the group with one intraarticular drainage without suction. The rate of complications was not increased and the blood transfusion requirements were the lowest. CONCLUSION: This study shows that total knee replacement involving one intraarticular wound drainage without suction attains the best results.
