摘要(Abstract)：

[目的]探讨采用异体肌腱重建膝关节前交叉韧带(anterior cruciate ligament,ACL)术后移植物的转归,为术后康复提供指导依据。[方法]2012年1月~2015年12月对行ACL重建术后1年以上的患者58例(58膝)进行随访,同时进行患膝关节镜下再探查(second-look);ACL重建手术时患者年龄18~52岁,平均(30.7±9.9)岁,均采用深冻异体肌腱作为重建移植物。比较手术前后膝关节功能恢复情况(Lysholm评分及International Knee Documentation Committee,IKDC评分)及膝关节前向稳定性(前抽屉试验、Lachman试验变化以及KT-1000侧侧差值);行二次关节镜检查,观察移植物连续性、移植物滑膜覆盖情况以及关节内是否有异生结构等。[结果]所有患者未发生感染、严重排异反应及其他严重并发症。ACL重建术后至末次随访时间为12~33个月,所有患者均行关节镜下再探查。末次随访时除1例患者出现约10°伸直受限,其余患者膝关节活动度基本正常。Lysholm评分由术前的(55.64±9.43)分提高至末次随访时的(86.40±4.78)分,IKDC评分由术前的(55.73±9.97)分提高至末次随访时的(85.75±4.97)分,差异有统计学意义(P<0.05);KT-1000侧侧差值由术前的(6.62±1.28)分提高至末次随访时的(1.57±0.98)分,差异有统计学意义(P<0.05)。关节镜下再探查结果:3例出现移植物完全吸收,连续性不佳;3例出现ACL移植物磨损;2例患者关节腔内可见Cyclops样结节。滑膜覆盖评价:移植物滑膜覆盖优22例,良24例,差12例;滑膜覆盖优良率为79.3%。滑膜覆盖优组和良组其Lysholm评分、IKDC评分、KT-1000侧-侧差值均优于滑膜覆盖差组,差异有统计学意义(P<0.05)。[结论]采用异体肌腱ACL重建术后移植物血管化、滑膜化进程慢,康复计划应相对缓慢;关节镜下再探查所见能够作为术后康复的良好依据。
