Predictive factors for bilateral discoid lateral meniscus in patients with symptomatic discoid lateral meniscus

摘要

Purpose: Although the incidence of bilateral discoid lateral meniscus (DLM) has been reported to range between 5-20% traditionally, recent reports demonstrated bilateral DLM in 70-90% was diagnosed by magnetic resonance imaging (MRI) or arthroscopic evaluation of bilateral sides. However, very little has been known about which prognostic factors could influence the bilaterality and tear of contralateral side. The purposes of this study were to assess which predictive factors could influence on the bilaterality and tear of patients with a symptomatic DLM. We hypothesized that there would be a correlation between the younger ages or severe tear pattern in symptomatic DLM and the associated tear imaged by MRI in contralateral knee.
