To identify the frequency of passing return-to-activity tests after anterior cruciate ligament reconstruction (ACLR) and to investigate the influence of patient-specific factors on pass rates. We hypothesized that isolated strength tests would be most difficult to pass and that graft type would be the most influential factor.
Cross-sectional.
Laboratory.
Eighty patients with a history of primary, unilateral ACLR, and 80 healthy controls participated.
Bilateral isokinetic strength, isometric strength, and single-leg hop tests were recorded during a single visit. The International Knee Documentation Committee (IKDC) Subjective Knee Evaluation measured subjective knee function, and the Tegner Activity Scale measured physical activity level.
Pass rates were calculated for 3 thresholds of absolute between-limb asymmetry: 0% to 10%, 11% to 15%, and 16% to 20%. Pass rates were compared by sex (male and female), graft type (patellar and hamstrings), meniscal procedure (yes and no), physical activity level (</≥ median Tegner), and time from surgery (</≥ 6 months).
Isokinetic quadriceps strength was consistently most difficult to pass, whereas the 6-meter timed hop and crossover hop tests were easiest. Graft type had the greatest influence on pass rates (isometric quadriceps and hamstring strength, hamstrings-to-quadriceps ratio), followed by time from surgery (6-meter timed hop and crossover hop), physical activity (IKDC), and meniscal procedure (6-meter timed hop).
Isokinetic quadriceps strength was the most difficult test to pass, and single-leg hop tests were the easiest. Patient-specific factors including graft type, time from surgery, physical activity level, and meniscal procedure may influence the ability to meet return-to-activity criterion after ACLR.
确定前交叉韧带重建（ACLR）后通过重返活动测试的频率，并探讨患者特定因素对通过率的影响。我们假设孤立的力量测试将是最难通过的，而移植物类型将是最具影响力的因素。
横断面研究。
实验室。
80 名有单侧 ACLR 病史的患者和 80 名健康对照者参加了研究。
在一次就诊中记录双侧等速力量、等长力量和单腿跳跃测试。国际膝关节文献委员会（IKDC）主观膝关节评估测量主观膝关节功能，Tegner 活动量表测量身体活动水平。
通过 3 个绝对肢体间不对称阈值计算通过率：0%至 10%、11%至 15%和 16%至 20%。通过性别（男性和女性）、移植物类型（髌腱和腘绳肌）、半月板手术（是和否）、身体活动水平（</≥中位数 Tegner）和手术时间（</≥6 个月）比较通过率。
等速股四头肌力量始终是最难通过的测试，而 6 米计时跳跃和交叉跳跃测试则是最容易的。移植物类型对通过率的影响最大（等长股四头肌和腘绳肌力量、腘绳肌/股四头肌比），其次是手术时间（6 米计时跳跃和交叉跳跃）、身体活动（IKDC）和半月板手术（6 米计时跳跃）。
等速股四头肌力量是最难通过的测试，单腿跳跃测试是最容易的。患者特定因素，包括移植物类型、手术时间、身体活动水平和半月板手术，可能会影响 ACLR 后达到重返活动标准的能力。
