INTRODUCTION Recently, there has been a call for vertical jump testing via force-plate analysis to be included in the assessment of individuals after anterior cruciate ligament reconstruction (ACLR) and as part of return-to-play criteria. However, a synthesis of current literature is needed to help guide clinicians on what tests to perform, which force-plate metrics to assess, and how these may change over the time course of rehabilitation. METHODS Four online databases were searched from inception to July 2022. The Downs and Black checklist was used to assess study quality. Multilevel meta-analyses and meta-regressions were undertaken in conjunction with a best evidence synthesis. RESULTS Forty-two articles were included, capturing 2375 participants with a history of ACLR. Reconstructed limbs displayed 1) lower peak eccentric forces, concentric forces, landing forces, and lower eccentric and concentric impulses (standardized means difference [SMD] = -1.84 to -0.46) than uninjured contralateral limbs during bilateral countermovement jumps (CMJ) and drop vertical jumps (DVJ); 2) lower jump heights and reactive strength indices (RSI), and longer contact times than uninjured contralateral limbs during unilateral CMJ and DVJ (SMD = -0.86 to 0.26); and 3) lower jump heights, RSI, and longer contact times during bilateral and unilateral CMJ, and unilateral DVJ, than uninjured controls (SMD = -1.19 to 1.08). Meta-regression revealed that time postsurgery was a significant moderator ( P < 0.05) for 1) bilateral CMJ height, peak concentric force, and peak landing force; 2) between-limb differences in unilateral CMJ height; and 3) differences in unilateral DVJ height, RSI, and contact time between reconstructed limbs and healthy controls with no history of injury. CONCLUSIONS Individuals with a history of ACLR display chronic deficits in vertical jumping performance during a range of bilateral and unilateral tasks, which may have implications for return-to-play criteria and the design of interventions targeted at restoring long-term deficits in explosive lower limb strength after ACLR.

前十字韧带重建后的垂直弹跳测试：系统回顾和荟萃分析。


简介 最近，有人呼吁通过测力板分析进行垂直弹跳测试，将其纳入前十字韧带重建 (ACLR) 后的个人评估中，并作为重返比赛标准的一部分。然而，需要综合当前的文献来帮助指导临床医生执行哪些测试、评估哪些测力台指标，以及这些指标在康复过程中如何变化。方法 从开始到 2022 年 7 月检索了四个在线数据库。使用 Downs 和 Black 检查表来评估研究质量。多层次荟萃分析和荟萃回归与最佳证据综合结合进行。结果 纳入 42 篇文章，涵盖 2375 名有 ACLR 病史的参与者。重建肢体显示 1) 在双边反向运动跳跃 (CMJ) 和垂直下降过程中，峰值偏心力、同心力、着陆力以及偏心和同心脉冲（标准化均值差 [SMD] = -1.84 至 -0.46）低于未受伤的对侧肢体跳跃（DVJ）； 2) 在单侧 CMJ 和 DVJ 期间，与未受伤的对侧肢体相比，跳跃高度和反应强度指数 (RSI) 较低，接触时间较长（SMD = -0.86 至 0.26）； 3) 与未受伤对照组相比，双侧和单侧 CMJ 以及单侧 DVJ 期间的跳跃高度、RSI 更低，接触时间更长（SMD = -1.19 至 1.08）。荟萃回归显示，术后时间是 1) 双侧 CMJ 高度、峰值同心力和峰值着地力的显着调节因素 ( P < 0.05)； 2）单侧CMJ高度的肢体间差异； 3) 重建肢体与无损伤史的健康对照之间单侧 DVJ 高度、RSI 和接触时间的差异。 结论 有 ACLR 病史的个体在一系列双边和单边任务中表现出垂直跳跃表现的慢性缺陷，这可能对重返比赛标准和旨在恢复爆发性下肢长期缺陷的干预措施的设计产生影响ACLR 后的强度。
