我们报告了一项前瞻性研究，评估了在一组匹配良好的接受腘绳肌或髌骨肌腱移植治疗前交叉韧带（ACL）缺损的患者中隧道增宽的发生率和程度。隧道增宽与临床因素、膝关节评分、KT-1000和等速肌力相关，以确定这一发现的临床意义。对73例ACL重建后至少12个月的患者进行了评价。38例患者接受了双半腱和股薄肌移植，35例接受了骨-髌骨肌腱-骨移植。所有患者均接受了类似的内窥镜手术，并加速了术后康复。使用标准化的前后位（AP）和侧位X线片（经放大调整）确定隧道扩大。进行了有限系列的MRI以验证这些测量结果。两组间隧道增宽程度有显著差异。腘绳肌组股骨隧道面积平均增加100.4%，而髌腱组减少25%（P = 0.001）。
We report a prospective series evaluating the incidence and degree of tunnel widening in a well-matched series of patients receiving a hamstring or patella tendon graft for anterior cruciate ligament (ACL) deficiency. The correlated tunnel widening with clinical factors, knee scores, KT-1000 and isokinetic muscle strength to determine the clinical significance of this finding. Seventy-three patients at least 12 months post-ACL reconstruction were evaluated. Thirty-eight patients had received a doubled semitendinous and gracilis graft and 35 a bone-patella tendon-bone graft. All patients underwent a similar endoscopic procedure and accelerated postoperative rehabilitation. Tunnel widening was determined using standardized anteroposterior (AP) and lateral X-rays adjusted for magnification. A limited series of MRIs was performed to validate these measurements. There was a significant difference in the degree of tunnel widening between the two groups. The mean increase in femoral tunnel area in the hamstring group was 100.4% compared with a decrease of 25% in the patella tendon group (P =
