目的总结采用漂浮体位下关节镜联合Burks and SchaVer's入路带线锚钉内固定治疗后交叉韧带（posterior cruciate ligament, PCL）胫骨止点撕脱骨折的临床疗效。 方法2010年5月－2014年3月，收治21例PCL胫骨止点撕脱骨折患者。男13例，女8例；年龄21~62岁，平均39.1岁。致伤原因：交通事故伤10例，运动损伤5例，高处坠落伤6例。受伤至入院时间为1~6 d，平均2.5 d。后抽屉试验均为阳性，前抽屉试验及内、外侧翻应力试验均为阴性。术前膝关节Lysholm评分为（28.0±5.5）分；国际膝关节文献委员会（IKDC）评分为（46.2±7.6）分。骨折按Meyer分型标准，Ⅱ型11例，Ⅲ型10例。术中患者取漂浮体位，常规关节镜入路并处理关节内病变；然后患者更换体位固定于侧卧位，采用Burks and SchaVer's入路，显露并固定撕脱骨折块。术后指导患者功能锻炼。 结果术后切口均Ⅰ期愈合，无神经、血管损伤及关节感染等并发症发生。患者均获随访，随访时间18~36个月，平均27.2个月。术后3个月，X线片复查示膝关节骨折复位良好，骨折均愈合；后抽屉试验及反Lachman试验均为阴性。患者关节活动度恢复至伤前水平。末次随访时，膝关节Lysholm评分为（90.9±1.4）分，与术前比较差异有统计学意义（t=54.584，P=0.000）。IKDC评分为（90.5±5.3）分，与术前比较差异有统计学意义（t=15.638，P=0.000）；其中A级19例，B级2例。 结论采用漂浮体位关节镜联合Burks and SchaVer’s入路带线锚钉内固定治疗PCL胫骨止点撕脱骨折，手术创伤小，入路安全可靠，术后允许早期康复锻炼，膝关节功能恢复满意
