A new CT-based classification system for posterior cruciate ligament tibial avulsion fractures: a nationwide multicenter study.

ABSTRACT:

Background

The Meyers-McKeever two-dimensional classification has been widely used in diagnosing and treating posterior cruciate ligament avulsion fractures since its introduction in 1959. However, because of image overlap and obscuration on knee radiographs, the type of avulsion fracture injury is often not identified, which can lead to misdiagnosis. CT has a higher overall confidence in size assessment, displacement, and degree of comminution of the posterior cruciate ligament avulsion fracture block compared with X-ray. Therefore, this study aims to propose a new classification system based on CT for posterior cruciate ligament avulsion fractures.

Methods

This multicenter study evaluated 523 patients with posterior cruciate ligament avulsion fractures admitted between Jul
