A comprehensive battery of tests are used to inform return to play decisions following anterior cruciate ligament (ACL) reconstruction. Performance measures contribute to patient function, but it is not clear if achieving symmetrical performance on strength and hop tests is sufficient or if a patient also needs to meet minimum unilateral thresholds.
HYPOTHESIS/PURPOSE: To determine the association of quadriceps strength and single-leg forward hop performance with patient-reported function, as measured by the IKDC Subjective Knee Form (IKDC), during late-stage ACL rehabilitation. A secondary purpose was to determine which clinical tests were the most difficult for participants to pass.
Descriptive Laboratory Study.
Forty-eight individuals with a history of ACL-R (32 female, 16 male; mean±SD age=18.0±2.7 y; height=172.4±7.6 cm; mass=69.6±11.4 kg; time since surgery=7.7±1.8 months; IKDC=86.8±10.6) completed the IKDC survey, quadriceps isometric strength, and single-leg forward hop performance. The relationship between IKDC scores and performance measures (LSI and involved limb) was determined using stepwise linear regression. Frequency counts were used to determine whether participants met clinical thresholds (IKDC 90%, quadriceps and single-leg forward hop LSI 90%, quadriceps peak torque 3.0 Nm/kg, and single-leg forward hop 80% height for females and 90% height for males).
Quadriceps LSI and involved limb peak torque explained 39% of the variance in IKDC scores while measures of single-leg forward hop performance did not add to the predictive model. Nearly 90% of participants could not meet established clinical thresholds on all five tests and quadriceps strength (LSI and peak torque) was the most common unmet criteria (71% of participants).
During late-stage ACL rehabilitation deficits in quadriceps strength contribute more to patient function and are greater in magnitude compared to hop test performance.

一系列综合测试用于指导前交叉韧带（ACL）重建术后的重返运动决策。性能指标有助于评估患者功能，但尚不清楚在力量和单腿跳测试中达到对称表现是否足够，或者患者是否还需要达到最低单侧阈值。
假设/目的：确定在ACL康复后期，通过国际膝关节文献委员会主观膝关节评分表（IKDC）测量的股四头肌力量和单腿向前跳性能与患者报告的功能之间的关联。第二个目的是确定哪些临床测试对参与者来说最难通过。
描述性实验室研究。
48名有ACL重建史的个体（32名女性，16名男性；平均±标准差年龄=18.0±2.7岁；身高=172.4±7.6厘米；体重=69.6±11.4千克；术后时间=7.7±1.8个月；IKDC=86.8±10.6）完成了IKDC调查、股四头肌等长力量测试和单腿向前跳性能测试。使用逐步线性回归确定IKDC评分与性能指标（肢体对称指数[LSI]和患侧肢体）之间的关系。使用频数计数来确定参与者是否达到临床阈值（IKDC≥90%，股四头肌和单腿向前跳LSI≥90%，股四头肌峰值扭矩≥3.0牛米/千克，女性单腿向前跳≥80%身高，男性≥90%身高）。
股四头肌LSI和患侧肢体峰值扭矩解释了IKDC评分中39%的变异量，而单腿向前跳性能指标并未增加预测模型的解释力。近90%的参与者在所有五项测试中均未达到既定的临床阈值，股四头肌力量（LSI和峰值扭矩）是最常见的未达标准（71%的参与者）。
在ACL康复后期，股四头肌力量不足对患者功能的影响更大，且与单腿跳测试性能相比，程度更严重。
