This study aimed to determine if patients with chronic ankle instability (CAI) exhibit biomechanical changes associated with the increased risk of anterior cruciate ligament (ACL) injury during landing tasks.
This study was conducted through systematic review and meta-analysis.
Searches were conducted in May 2024 across five electronic databases, including Web of Science, Scopus, PubMed, SPORTDiscus, and Cochrane Library.
Studies were included if they (1) involved subjects with CAI and healthy controls and (2) assessed biomechanical variables such as ground reaction forces, joint angles, and joint torques.
Of the 675 identified studies, 171 were included in the review, and 13 were eligible for meta-analysis. The reviewed studies clearly defined research objectives, study populations, consistent participant recruitment, and exposures, and they used valid and reliable measures for outcomes. However, areas such as sample size calculation, study sample justification, blinding in assessments, and addressing confounders were not robust. This meta-analysis involved 542 participants (healthy group: n = 251; CAI group: n = 291). Compared with healthy individuals, patients with CAI exhibited a greater peak vertical ground reaction force (peak VGRF; SMD = 0.30, 95% CI: 0.07-0.53, = 0.009), reduced hip flexion angles (SMD = -0.30, 95% CI: -0.51 to -0.17, < 0.0001), increased trunk lateral flexion (SMD = 0.47, 95% CI: 0.05 to 0.9, = 0.03), greater hip extension moments (SMD = 0.47, 95% CI: 0.09-0.84, = 0.02), and increased knee extension moments (SMD = 0.39, 95% CI: 0.02-0.77, = 0.04).
During landing tasks, patients with CAI demonstrate increased hip extension moments and knee extension moments, decreased hip flexion angles, increased peak VGRF, and increased trunk lateral flexion angles. These biomechanical variables are associated with an elevated risk of ACL injuries.

本研究旨在确定慢性踝关节不稳（CAI）患者在着陆任务期间是否表现出与前交叉韧带（ACL）损伤风险增加相关的生物力学变化。
本研究通过系统评价和荟萃分析进行。
于2024年5月在五个电子数据库中进行检索，包括科学引文索引、Scopus、PubMed、体育数据库和考科蓝图书馆。
纳入的研究需满足以下条件：（1）涉及CAI患者和健康对照者；（2）评估生物力学变量，如地面反作用力、关节角度和关节扭矩。
在675项已识别的研究中，171项被纳入综述，13项符合荟萃分析的条件。纳入综述的研究明确界定了研究目标、研究人群、一致的参与者招募和暴露情况，并且对结果采用了有效且可靠的测量方法。然而，诸如样本量计算、研究样本合理性、评估中的盲法以及混杂因素处理等方面并不完善。该荟萃分析纳入了542名参与者（健康组：n = 251；CAI组：n = 291）。与健康个体相比，CAI患者表现出更大的垂直地面反作用力峰值（峰值VGRF；标准化均数差[SMD]=0.30，95%置信区间[CI]：0.07 - 0.53，P = 0.009）、髋关节屈曲角度减小（SMD = -0.30，95% CI：-0.51至-0.17，P < 0.0001）、躯干侧屈增加（SMD = 0.47，95% CI：0.05至0.9，P = 0.03）、髋关节伸展力矩更大（SMD = 0.47，95% CI：0.09 - 0.84，P = 0.02）以及膝关节伸展力矩增加（SMD = 0.39，95% CI：0.02 - 0.77，P = 0.04）。
在着陆任务期间，CAI患者表现出髋关节伸展力矩和膝关节伸展力矩增加、髋关节屈曲角度减小、峰值VGRF增加以及躯干侧屈角度增加。这些生物力学变量与ACL损伤风险升高相关。
