BACKGROUND
Altered knee joint loading is pervasive and persistent after anterior cruciate ligament reconstruction (ACLR) and a significant driver for the development of knee osteoarthritis (OA).
PURPOSE
To describe a prospective, parallel, randomized controlled trial aiming to evaluate the efficacy of an eight-week squat visual biofeedback program implemented early after ACLR.
STUDY DESIGN
Randomized controlled clinical trial.
METHODS
Thirty-four individuals (13-35 years of age) will be recruited for a prospective, parallel, randomized controlled trial. Embedded within progressive, criterion-based post-operative physical therapy, participants will be randomly allocated to an eight-week bodyweight squatting program either with or without visual biofeedback initiated when 50% weightbearing is allowed by the treating surgeon. Outcomes will be measured at pre- and post-intervention, six months post-ACLR, and nine months post-ACLR. The primary outcomes are 1) change in knee flexion moment impulse interlimb ratio during squatting at post-intervention, and 2) change in cartilage microstructure from pre-intervention to six months. Secondary outcomes include 1) knee flexion moment impulse interlimb ratio during squatting at six months post-ACLR, 2) peak knee flexion moment interlimb ratio during gait at post-intervention and six months post-ACLR, and 3) quadriceps strength at post-intervention and six months post-ACLR. Exploratory outcomes include knee range of motion and effusion, single-legged hop tests, daily physical activity, additional movement biomechanics, and patient-reported outcomes.
DISCUSSION
This study will assess the efficacy of an eight-week squat visual biofeedback program implemented early after ACLR. Findings will inform the future development and testing of comprehensive knee loading rehabilitation interventions that seek to optimize both the magnitude and frequency of knee joint loading to prevent early knee OA after ACL injuries.
LEVEL OF EVIDENCE
NA.
TRIAL REGISTRATION
Clinicaltrials.gov reference: NCT05363683. Registered May 6, 2022.
背景
前交叉韧带重建（ACLR）后膝关节负荷改变普遍且持续存在，是膝关节骨关节炎（OA）发展的重要驱动因素。
目的
描述一项前瞻性、平行、随机对照试验，旨在评估ACLR术后早期实施的为期八周的深蹲视觉生物反馈计划的疗效。
研究设计
随机对照临床试验。
方法
将招募34名年龄在13至35岁之间的个体进行前瞻性、平行、随机对照试验。在基于标准的术后渐进性物理治疗中，参与者将被随机分配到一个为期八周的体重深蹲计划，该计划在治疗外科医生允许50%负重时开始，有或没有视觉生物反馈。在干预前、干预后、ACLR后六个月和ACLR后九个月测量结果。主要结果是：1）干预后深蹲时膝关节屈曲力矩冲动肢体间比率的变化，以及2）从干预前到六个月软骨微观结构的变化。次要结果包括：1）ACLR后六个月深蹲时膝关节屈曲力矩冲动肢体间比率，2）干预后和ACLR后六个月步态中膝关节屈曲力矩峰值肢体间比率，以及3）干预后和ACLR后六个月股四头肌力量。探索性结果包括膝关节活动范围和积液、单腿跳测试、日常身体活动、额外的运动生物力学以及患者报告的结果。
讨论
本研究将评估ACLR术后早期实施的为期八周的深蹲视觉生物反馈计划的疗效。研究结果将为未来全面膝关节负荷康复干预措施的开发和测试提供信息，这些干预措施旨在优化膝关节负荷的大小和频率，以预防ACL损伤后早期膝关节OA。
证据水平
