We evaluated the effects of six different prophylactic braces on ACL ligament strain under dynamic valgus loads using a mechanical surrogate limb validated against human cadaveric specimens. Medical collateral ligament and anterior cruciate ligament peak forces, medial collateral ligament and anterior cruciate ligament tension initiation times, and impact safety factors were calculated for both braced and unbraced conditions. These tests were conducted to determine whether or not application of a prophylactic brace might provide protection to the anterior cruciate ligament under valgus loading conditions. The results of this study indicate that those braces that increased impact duration appear to differentially protect the anterior cruciate ligament more than the medial collateral ligament, and that most of the braces tested appear to provide some degree of protection to the anterior cruciate ligament under direct lateral impacts. These findings should be confirmed clinically.
我们使用经人体尸体标本验证的机械替代肢体，评估了六种不同预防性护具在动态外翻负荷下对前交叉韧带应变的影响。计算了佩戴护具和未佩戴护具情况下的内侧副韧带和前交叉韧带峰值力、内侧副韧带和前交叉韧带张力起始时间以及冲击安全系数。进行这些测试是为了确定预防性护具的应用在外翻负荷条件下是否可能为前交叉韧带提供保护。本研究结果表明，那些增加冲击持续时间的护具似乎比内侧副韧带更能有差别地保护前交叉韧带，并且大多数测试的护具在直接外侧冲击下似乎能为前交叉韧带提供一定程度的保护。这些发现应在临床上得到证实。
