Rehabilitation following anterior cruciate ligament (ACL) reconstructions is based mainly on comprehensive progressive exercise programmes using a multi-dimensional approach. Elastic knee sleeves may be useful adjuncts to rehabilitation. The aim of this study was to determine the immediate and 6-week effects of wearing a knee sleeve on person-reported outcomes and function in participants who had undergone an ACL reconstruction and who had residual self-reported functional limitations.
Individuals with ACL reconstruction in the previous 6 months to 5 years were recruited. Immediate effects of a commercially-available elastic knee sleeve on single-leg horizontal hop distance were explored using a cross-over design. Following this first session, participants were randomised into a Control Group and a Sleeve Group who wore the sleeve for 6 weeks, at least 1 h daily. Outcome measures for the randomised clinical trial (RCT) were the International Knee Documentation Classification Subjective Knee Form (IKDC-SKF) score, the single-leg horizontal hop distance, and isokinetic quadriceps and hamstring peak torque. Linear mixed models were used to determine random effects. Where both limbs were measured at multiple time points, a random measurement occasion effect nested within participant was used.
Thirty-four individuals (16 women) with ACL reconstruction completed the cross-over trial. Hop distance for the injured side during the sleeve condition increased by 3.6 % (95 % CI 0.4-6.8 %, p = 0.025). There was no evidence of differential changes between groups for the IKDC-SKF (Sleeve Group n = 15; Control Group n = 16; p = 0.327), or relative improvement in the injured side compared to the uninjured side for the physical performance measures (Sleeve Group n = 12, Control Group n = 12; three-way interaction p = 0.533 [hop distance], 0.381 [quadriceps isokinetic peak torque], and 0.592 [hamstring isokinetic peak torque]).
Single-leg hop distance of the ACL reconstructed side improved when wearing a knee sleeve. Wearing the knee sleeve over 6 weeks did not lead to enhanced improvements in self-reported knee function, hop distance and thigh muscle strength compared to the control group.
The trial was prospectively registered with the Australia New Zealand Clinical Trials Registry No: ACTRN12618001083280 , 28 June 2018.
前交叉韧带（ACL）重建后的康复主要基于使用多维方法的综合渐进运动方案。弹性膝关节套可能是康复的有用辅助手段。本研究的目的是确定在 ACL 重建后仍有自我报告功能障碍的参与者中，佩戴膝关节套对个体报告的结果和功能的即刻和 6 周影响。
招募 ACL 重建后 6 个月至 5 年内的个体。使用交叉设计探索市售弹性膝关节套对单腿水平跳跃距离的即刻影响。在第一阶段之后，参与者被随机分为对照组和套管组，套管组在 6 周内每天至少佩戴 1 小时。随机临床试验（RCT）的结果测量指标为国际膝关节文献委员会主观膝关节评分（IKDC-SKF）、单腿水平跳跃距离以及等速股四头肌和腘绳肌峰值扭矩。使用线性混合模型确定随机效应。如果双侧肢体在多个时间点进行了测量，则使用随机测量时间点效应嵌套在参与者内。
34 名（16 名女性）ACL 重建的个体完成了交叉试验。套管条件下受伤侧的跳跃距离增加了 3.6%（95%CI 0.4-6.8%，p=0.025）。在 IKDC-SKF 方面，两组之间没有证据表明差异变化（套管组 n=15；对照组 n=16；p=0.327），或者与未受伤侧相比，受伤侧的身体表现测量值相对改善（套管组 n=12，对照组 n=12；三向交互 p=0.533[跳跃距离]、0.381[股四头肌等速峰值扭矩]和 0.592[腘绳肌等速峰值扭矩]）。
当佩戴膝关节套时，ACL 重建侧的单腿跳跃距离得到改善。与对照组相比，佩戴膝关节套 6 周并没有导致自我报告的膝关节功能、跳跃距离和大腿肌肉力量的改善得到增强。
该试验于 2018 年 6 月 28 日在澳大利亚和新西兰临床试验注册中心进行了前瞻性注册（注册号：ACTRN12618001083280）。
