Background

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.

Methods

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.

Findings

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.

Interpretation

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.

膝后斜韧带的生物力学

背景

该系统文献综述的目的是分析膝盖后斜韧带的孤立生物力学。在目前的文献中，在几篇文章中分析了后斜韧带的生物力学方面，但是这总是与其他囊状韧带结构相关联的。

方法

对现有文献进行了系统综述，以鉴定所有涉及后斜韧带生物力学的研究。两名独立研究人员使用MEDLINE，CINAHL，Scopus，Embase和Cochrane数据库进行了研究。

发现

共有10篇文章分析了后斜韧带的生物力学，证实了该韧带对于膝盖在不同位置的稳定性的重要性。后斜韧带是抵抗早期屈曲角度（0°–30°）内旋转的主要稳定器，并且是对后十字韧带不足的膝盖进行胫骨后平移的重要限制。此外，在模拟枢轴变速操纵时，后斜韧带最多可承受前十字韧带承受的47％的阻力，以抵抗内部旋转载荷。

解释

这项研究证实，后斜韧带在解剖学上是明确定义的且独特的结构，在稳定膝盖，尤其是在内部旋转中起关键作用。后斜韧带经常与其他解剖结构一起受伤。未来的研究应开发临床测试以评估后斜韧带的功能和稳定性。
