2、动。术后3、6及12个月的Lysholm评分分别为(73．87-_+-3．16)、(9O．14±1．99)及(90．864-1．17)分，均显著高于术前的(48．8±5．11)分(P值均O．05)。术后3、6及12个月的Tegner评分分别为(5．6O±0．51)、(7．53土0．52)及(7．73±0．46)分，均显著高于术前的(1．93±0．96)分(P值均0．05)。根据国际膝关节评分委员会的评分标准分级为A12

3、例，B3例。结论对于单纯性膝关节PCL断裂并有手术指征的患者，采用关节镜下LARS人工韧带重建PCL的创伤小，可取得较好的疗效。【关键词】韧带增强重建系统人工韧带；后交叉韧带；重建ReconstructionofarthroscopicposteriorcruciateIigamentbyIigamentadvancedreinforcementsystemartificialligamentYUANYongjun，HEGuochu，CENJianping，ZHANGZhenqing，SUNChanghui．DepartmentofOrthopaedics，RuqinHos
