摘要
目的:比较自体腘绳肌腱重建前交叉韧带(ACL)过程中,采用Endobutton和Rigidfix两种股骨端韧带固定方式的疗效。方法:回顾性研究了48例陈旧性ACL病例,其中A组24例,B组24例;分别应用自体半腱肌、股薄肌腱重建ACL,其中A组股骨端固定采用Rigidfix交锁钉,B组采用Endobutton纽扣钢板,两组胫骨端固定均为Intrafix界面螺钉+Spiked Washer栓桩固定。平均随访27个月,采用MRI测量两组骨隧道扩大情况,并用Lysholm、TegnerI、KDC、KT1000对患膝进行术前、术后测试和评分。结果:MRI测量发现,B组股骨端和胫骨端骨隧道扩大均较A组明显(P<0.05)。两组病人术后Lysholm、TegnerI、KDC评分均较术前明显提高,KT1000测试结果较术前明显改善(P<0.05);但两组间术后评分无显著性差异(P>0.05)。结论:在自体腘绳肌腱重建前交叉韧带中,与采用Rigidfix固定相比,股骨端采用Endobutton固定自体腘绳肌腱更容易引起术后骨隧道扩大,但在临床疗效上两种固定方式并无明显差别。
Objective To compare the clinical results of Endobutton and Rigidfix graft fixation at the femoral tunnel after ACL reconstruction with hamstring autografts.Methods 48 patients accepting ACL reconstruction with hamstring autografts were retrospective studied.According to different fixation adopted at the femoral tunnel,they were divided into group A（24 patients,with Rigidfix cross pin）and group B（24 patients,with Endobutton）.All cases were fixed with Intrafix interference screw and Spiked Washer screw at the tibial tunnel.The average follow-up time was 27 months.KT-1000 arthrometric measurement and the IKDC,Lysholm,Tegner scores were used for evaluation.The diameter of bone tunnel was also measured by MRI.Results Tunnel widening were found in both groups,but the increase of both the femoral and tibial tunnels in group B were significantly greater than group（P 0.05.） In both groups after operation,there was significantly increases of IKDC subjective scores,Lysholm scores,Tegner scores and KT-1000 results also had obviously improvement（P 0.05）.But no significant difference was found between two groups after operation.Conclusion Compared with double cross-pins for fixation at the femoral tunnel,tunnel widening was more prone to happen when using Endobutton suspensory fixation system.
