Avulsion of the Anterior Lateral Meniscal Root Secondary to Tibial Eminence Fracture.

The lateral tibial eminence shares a close relationship with the anterior root of the lateral meniscus. Limited studies have reported traumatic injury to the anterior meniscal roots in the setting of tibial eminence fractures, and reported rates of occurrence of concomitant meniscal and chondral injuries vary widely. The purpose of this article is to describe the case of a 28-year-old woman who had a complete avulsion of the anterolateral meniscal root caused by a tibial eminence fracture with resultant malunion and root displacement. The anterolateral meniscal root was anatomically repaired following arthroscopic resection of the malunited fragment.
