Ankle and knee injuries are two of the most common injuries. It has been shown that ankle sprains can lead to chronic ankle instability thereby affecting the function of the ankle. Since the lower extremity is a kinetic chain anything that affects the ankle is thought to affect the knee and hip as well. Changes in lower extremity function associated with chronic ankle instability may predispose patients for non-contact ACL injuries. The purpose of this study was to provide a systematic review of the research done on chronic ankle instability (CAI) and lower extremity kinematics during landing tasks. SportsDiscus, PubMed, and CINAHL were used to search "ankle instability" and "landing kinematics." Included articles must have evaluated patients with chronic ankle instability and have identified kinematic changes at the knee to be included in the review. A total of 338 subjects participated in the six studies identified. The principal findings in these studies were that CAI subjects had decreased knee flexion compared to the control group. Hip flexion was the same between CAI and control groups and dorsiflexion range of motion had mixed results. Patients with chronic ankle instability demonstrate decreased knee flexion. Decreased knee flexion has shown to be a key risk factor in non-contact knee injuries. In the future, more research needs to be done comparing chronic ankle instability to non-contact knee injury rates.
踝关节和膝关节损伤是最常见的两种损伤。研究表明，踝关节扭伤可导致慢性踝关节不稳定，从而影响踝关节功能。由于下肢是一个动力链，任何影响踝关节的因素都被认为也会影响膝关节和髋关节。与慢性踝关节不稳定相关的下肢功能变化可能使患者易患非接触性前交叉韧带损伤。本研究的目的是对慢性踝关节不稳定（CAI）和着陆任务期间下肢运动学的相关研究进行系统综述。利用体育医学数据库（SportsDiscus）、医学期刊数据库（PubMed）和护理学与健康领域数据库（CINAHL）检索“踝关节不稳定”和“着陆运动学”。纳入的文章必须评估了慢性踝关节不稳定患者，并确定了膝关节的运动学变化，才能纳入综述。共有338名受试者参与了所确定的六项研究。这些研究的主要发现是，与对照组相比，CAI受试者的膝关节屈曲减少。CAI组和对照组之间的髋关节屈曲相同，背屈活动范围的结果不一。慢性踝关节不稳定患者表现出膝关节屈曲减少。膝关节屈曲减少已被证明是非接触性膝关节损伤的一个关键危险因素。未来，需要进行更多的研究，比较慢性踝关节不稳定与非接触性膝关节损伤率。
