Summary

The discoid meniscus, a common congenital knee variant in children, can cause snapping knee syndrome. Treatment depends on the type, with symptomatic Wrisberg ligament tears requiring surgical repair.

Area of Science:

  • Orthopedics
  • Pediatric Orthopedics
  • Sports Medicine

Background:

  • The discoid meniscus is the most common meniscal anomaly in children, often congenital and lateral.
  • Its abnormal shape increases tibial coverage and meniscus thickness, potentially causing knee joint shear forces.

Purpose of the Study:

  • To describe the discoid meniscus, its classifications, and associated conditions.
  • To outline management strategies for symptomatic discoid meniscus variants in pediatric patients.

Main Methods:

  • Review of the literature on discoid meniscus.
  • Classification of discoid meniscus based on the Watanabe system.
  • Discussion of clinical presentation and treatment options.

Main Results:

  • The Watanabe classification identifies three types: complete, incomplete, and Wrisberg ligament.
  • Complete and incomplete types are often asymptomatic and managed conservatively unless torn.
  • The Wrisberg ligament type can cause snapping knee syndrome due to posterior tibial attachment deficiency.

Conclusions:

  • Asymptomatic discoid menisci typically require no intervention.
  • Tears in complete/incomplete types are treated with resection to a stable rim.
  • Symptomatic Wrisberg ligament type necessitates surgical repair and potentially saucerization to prevent shear forces.
