背景资料：前交叉韧带（ACL）损伤和重建后的患者在康复过程中最常用的运动之一。目前，保险公司越来越多地要求在尝试手术重建之前进行强化康复试验。本研究的目的是探讨这种“安全”的康复锻炼在ACL缺陷的设置可能会导致改变膝关节kinematics.Methods：30例单侧ACL断裂被招募为这项研究。平均受伤时间为3.3个月。通过结合磁共振成像（MRI）、双透视和先进的计算机模型，在一次递增运动中测定胫股运动学。结果：ACL损伤的膝关节显示出比未损伤的膝关节平均大50的胫骨外旋（P
Background: Step-up exercise is one of the most commonly utilized exercises during rehabilitation of patients after both anterior cruciate ligament (ACL) injury and reconstruction. Currently, insurance providers increasingly required a trial of intensified rehabilitation before surgical reconstruction is attempted. The purpose of this study was to investigate whether this "safe" rehabilitation exercise in the setting of ACL deficiency can cause altered knee kinematics.Methods: Thirty patients with unilateral ACL rupture were recruited for this study. The mean time from injury was 3.3 months. Tibiofemoral kinematics were determined during a step-up exercise using a combination of magnetic resonance imaging (MRI), dual fluoroscopy and advanced computer modeling.Findings: The ACL-injured knee displayed an average 50 greater external tibial rotation than the uninjured knee (P
