摘　　要：背景背景:人工全膝关节置换术后出血与输血的问题越来越受到关注,而假体对术中截骨面的覆盖对术后引流的影响尚不明确。目的目的:比较不同假体覆盖率与人工全膝关节置换术后引流量的关系。方法方法:2012年5月至2012年10月30例接受全膝关节表面置换术的患者随机分为A组和B组,A组16例患者,男4例,女12例,平均年龄(66.6±8.2)岁。B组14例患者,男4例,女10例,平均年龄(74.6±5.3)岁。统计患者性别、年龄、体重、身高、体重指数、术后引流量、截骨后股骨及胫骨前后径和左右径、使用假体大小。结果结果:A组假体对于截骨面覆盖率较B组优良率高,分别为43.8%和21.4%,术后A组患者引流量为(378.1±266.1)ml,较B组术后引流量(473.2±243.2)ml明显减少。结论结论:人工全膝关节置换术中假体对于截骨面的覆盖率是影响术后引流量的主要因素之一,选择合适的假体覆盖对于减少术后引流有积极的意义。Background:Total knee arthroplasty (TKA) has become a common orthopedic procedure. Blood loss and transfusion are im-portant postoperative features that must be considered in TKA. Much attention has been focused on various methods to re-duce the blood loss. But match rate between prosthesis-bone that is another key factor affects the postoperative drainage of TKA has not been noticed. <br> Objective:To analyze the relationship between coverage rate of prosthesis and the drainage after TKA. <br> Methods:From May to October 2012, 30 patients underwent total knee arthroplasty and were randomly divided into group A and group B. There were 4 males and 12 females in group A with an average age of (66.6± 8.2) years. There were 4 males and 10 females in group B with an average age of (74.6 ± 5.3) years. Demographic, postoperative drainage, prosthesis size, mediolateral (tML) and anteroposterior (tAP) dimension of tibial and femoral in resected bone were collected. <br> Results:Compared with group B (21.4%), group A (43.8%) had a higher coverage rate of prothesis. Postoperative drainage was (378.1± 266.1) ml in group A and (473.2± 243.2) ml in group B. <br> Conclusions:The coverage rate of the prosthesis is one of the main factors affecting postoperative drainage. The appropriate prosthesis is very important to reduce postoperative drainage.
