This study examined the relationship between impairment of the knee and activity restriction during activities of daily living and sports following anterior cruciate ligament reconstruction. Knee range of motion, swelling, pain, instability, ligamentous laxity, isometric and isokinetic muscle function and performance-based measures of activity restriction were measured in 44 subjects. Four measures of patient-reported activity restrictions, including the Activities of Daily Living, Sports Activities Scales of the Knee Outcome Survey, and global ratings of function during activities of daily life and sports, were statistically combined to create a composite variable representing the level of patient-reported activity restrictions for each subject. Hierarchical regression analysis revealed that 17% of the variability in patient-reported activity restrictions was accounted for by age, length of postoperative follow-up, and mechanism of injury. Addition of the one-legged hop, Lachman, anterior drawer, and varus stress tests accounted for an additional 40% of the variability of function. When pain and giving way were added to the model, 79% of the variability was explained.
本研究探讨了前交叉韧带重建术后日常生活活动和运动期间膝关节功能障碍与活动受限之间的关系。对44名受试者测量了膝关节活动范围、肿胀、疼痛、不稳定、韧带松弛、等长和等速肌肉功能以及基于表现的活动受限指标。对四项患者报告的活动受限指标进行统计合并，包括日常生活活动、膝关节结果调查的体育活动量表以及日常生活活动和运动期间的整体功能评分，以创建一个代表每个受试者患者报告活动受限水平的复合变量。分层回归分析显示，患者报告的活动受限变异中有17%可由年龄、术后随访时间和损伤机制解释。加入单腿跳、拉赫曼试验、前抽屉试验和内翻应力试验后，功能变异又增加了40%。当将疼痛和打软腿加入模型时，可解释79%的变异。
