The purpose of this systematic literature review is to analyse the isolated biomechanics of the posterior oblique ligament of the knee. In the current literature, the biomechanical aspect of the posterior oblique ligament was analysed in several articles, but this was always done in association with other capsuloligamentous structures.
A systematic review of the existing literature was performed to identify all studies dealing with the biomechanics of the posterior oblique ligament. Two independent investigators performed the research using the MEDLINE, CINAHL, Scopus, Embase and Cochrane databases.
A total of 10 articles analysed the biomechanics of the posterior oblique ligament, confirming the importance of this ligament for the stability of the knee in different positions. The posterior oblique ligament is the main stabiliser against internal rotation in early flexion angles (0°-30°) and it is an important restraint to posterior tibial translation in the posterior cruciate ligament deficient knee. Furthermore, the posterior oblique ligament bears up to 47% of the force borne by the anterior cruciate ligament in resisting the internal rotation loads when a pivot-shift maneuver is simulated.
This review confirms that the posterior oblique ligament is an anatomically well-defined and distinct structure that plays a key role in stabilising the knee, especially in internal rotation. The posterior oblique ligament is frequently injured along with other anatomical structures. Future studies should develop clinical tests to evaluate the functionality and stability of the the posterior oblique ligament.
本系统文献回顾的目的是分析膝关节后斜韧带的孤立生物力学。在目前的文献中，后斜韧带的生物力学方面在几篇文章中进行了分析，但这总是与其他囊韧带结构一起进行的。
我们对现有文献进行了系统回顾，以确定所有涉及后斜韧带生物力学的研究。两名独立的调查员使用 MEDLINE、CINAHL、Scopus、Embase 和 Cochrane 数据库进行了研究。
共有 10 篇文章分析了后斜韧带的生物力学，证实了该韧带在膝关节不同位置稳定性方面的重要性。后斜韧带是在早期（0°-30°）屈曲角度下抵抗内旋的主要稳定器，在交叉韧带缺失的膝关节中是胫骨后移的重要限制物。此外，在后交叉韧带缺失的膝关节中，当模拟膝关节旋转不稳定试验时，后斜韧带承受了前交叉韧带抵抗内旋负荷的 47%的力。
本综述证实，后斜韧带是一种解剖结构明确的结构，在稳定膝关节方面起着关键作用，特别是在抵抗内旋方面。后斜韧带经常与其他解剖结构一起受伤。未来的研究应该开发临床测试来评估后斜韧带的功能和稳定性。
