比较三种不同的前交叉韧带（ACL）重建技术在ACL重建后1年恢复膝关节旋转稳定性的能力。在一项前瞻性随机研究中，我们测试了三种不同的ACL重建技术恢复膝关节旋转稳定性的能力。47例ACL缺陷（ACLD）患者随机接受经胫骨单束（SB）、解剖SB和双束ACL重建。术前和1年随访时进行三维运动分析，以评价胫骨旋转和旋转刚度。运动数据被捕获使用八个摄像头的运动分析系统。胫骨旋转测定在步行，跑步，和一个旋转任务。其他结果参数是KT-1000膝关节松弛度测量和主观结果评分KOOS和IKDC.Three-dimensional运动分析表明，胫骨内旋和旋转刚度没有不同的ACL重建技术在步行，跑步，并在1年的后续旋转。客观膝关节稳定性和主观结果评分在重建组之间没有差异。1年随访时，解剖和非解剖ACL重建技术之间的旋转稳定性行走、跑步和旋转无显著差异。治疗研究，I级。
To compare the ability of three different anterior cruciate ligament (ACL) reconstruction techniques to normalize rotational knee stability 1 year after ACL reconstruction. Two of these techniques are so-called anatomic techniques.Three different ACL reconstruction techniques were tested for their ability to normalize rotational knee stability in a prospective randomized study. Forty-seven ACL-deficient (ACLD) patients were randomized to transtibial single-bundle (SB), anatomic SB, and double-bundle ACL reconstruction. Three-dimensional motion analysis was performed preoperatively and at 1-year follow-up to evaluate tibial rotation and rotational stiffness. Motion data were captured using an eight-camera motion analysis system. Tibial rotation was determined during walking, running, and a pivoting task. Other outcome parameters were KT-1000 knee laxity measurements and the subjective outcome scores KOOS and IKDC.Three-dimensional motion analysis demonstrated that the tibial internal rotation and the rotational stiffness did not differ between the ACL reconstruction techniques during walking, running, and pivoting at 1-year follow-up. Objective knee stability and subjective outcome scores did not differ between the reconstruction groups.No significant difference in rotational stability walking, running, and pivoting was seen between anatomic and nonanatomic ACL reconstruction techniques at 1-year follow-up.Therapeutic study, Level I.
