Project Description

The purpose of this illustration is to visually classify lateral discoid meniscus (LDM) pathomorphology variations. The final figure is to be published in a research paper and accompanied by a written chart with descriptions of each variation shown. LDM is the most common congenital anomaly of the knee and is evaluated based on four features: meniscal width, meniscal height, peripheral stability, and meniscus tear (presence, location, type). Classification of LDM is difficult because of the wide spectrum and heterogeneity of its pathomorphology. In an effort to develop a reliable classification system for LDM, a group of pediatric orthopaedic surgeons from 20 academic North American institutions reviewed existing systems and developed a novel system. It is the first LDM classification system to be proposed and evaluated for reliability. This figure plays a vital role in representing the group’s novel research in an organized, visual manner to help standardize descriptions of LDM pathology to facilitate research, guide treatment, and improve outcomes of patient care.
