Radiographic evaluation of key anatomical markers in discoid lateral meniscus: a systematic review and meta-analysis.

ABSTRACT:

Purpose

The lateral discoid meniscus (DLM), a common anatomical variant in Asian populations, is often linked to knee pain, restricted motion, and an increased risk of meniscal tears. Due to limitations of magnetic resonance imaging (MRI) in certain patients, this study aims to assess the efficacy of X-ray parameters in diagnosing DLM, focusing on key features: lateral tibial spine height (LTSH), lateral joint space distance (LJSD), fibular head height (FHH), lateral tibial plateau obliquity (LTPO), and the condylar cut-off sign.

Methods

A systematic review and meta-analysis were conducted using studies from PubMed, Embase, and Web of Science (January 2004 - October 2024). Studies with observational designs, X-ray measurements, and data on DLM were included. Mean difference
