重返伤前运动水平时通过的力量与跳跃测试数量是否与二次ACL损伤相关？一项458例患者的登记研究
简介
这项基于康复登记数据的队列研究纳入458例15–35岁、初次ACL重建使用腘绳肌腱或髌腱自体移植物且伤前Tegner活动水平≥6的患者，分析重返伤前运动水平时5项力量与跳跃测试的通过项数是否与二次ACL损伤风险相关。全部随访期间60例（13%）发生二次ACL损伤，重返运动后1年内为32例（7.0%）；校正自体移植物类型、重返运动时间和BMI后，通过测试项数与…
英文摘要
OBJECTIVE: To analyze whether the number of strength and hop tests passed in a 5-test battery was associated with the hazard of second ACL injury after returning to pre-injury level of sports (RTS). DESIGN: Registry-based cohort study. SETTING: Data extracted in February 2026 from a rehabilitation registry. PARTICIPANTS: Patients aged 15-35 years at the time of primary ACL reconstruction with ipsilateral hamstring or patellar tendon autograft and pre-injury Tegner activity level ≥ 6. MAIN OUTCOME MEASURE: Second ACL injury after RTS, assessed during available follow-up and within one year of RTS using a Cox proportional hazard regression model. Hazard ratios with 95% confidence intervals were calculated and p-value was set to < 0.05. RESULTS: 458 patients were included. 60 (13%) second ACL injuries occurred within all available follow-up time, where 32 (7.0%) occurred within 1 year after RTS. No significant association was observed between number of tests passed and second ACL injury during available follow-up (p = 0.41), or within one year of RTS (p = 0.87), after adjustment for autograft type, time to RTS, and BMI. CONCLUSION: The number of tests passed in a 5-test muscle function battery was not associated with the hazard of second ACL injury after RTS.
