Evaluation of Different Patterns PHMM Root Tears

May 16, 2026 updated by: Ahmed Gamal Mohamed Ahmed, Assiut University

Evaluation Of Different Patterns Of Posterior Horn Medial Meniscus Root Tears

  1. To evaluate and classify different morphological patterns of posterior horn medial meniscus root tears (PHMMRTs) and assess their correlation with clinical presentation, MRI findings, and arthroscopic features.
  2. To determine the association between tear patterns and degree of meniscal extrusion.
  3. To evaluate the relationship between tear patterns and articular cartilage degeneration.
  4. To identify predictors of specific tear patterns based on clinical and radiological findings

Detailed Description

The medial meniscus posterior horn root plays a pivotal role in maintaining normal knee biomechanics by converting axial loads into circumferential hoop stresses. Injury to this structure leads to loss of meniscal function, increased tibiofemoral contact pressure, and accelerated degeneration of articular cartilage, resembling the biomechanical effects of total meniscectomy.

Posterior horn medial meniscus root tears (PHMMRTs) present with various morphological patterns, including radial tears, oblique tears, complex tears, and complete root avulsions. Each tear pattern has distinct clinical, radiological, and arthroscopic characteristics, which may influence management strategies and prognosis. Despite increasing recognition of these injuries, data correlating tear patterns with clinical presentation and imaging findings remain limited.

Despite increasing recognition of PHMMRTs, limited studies have comprehensively correlated different tear patterns with clinical, radiological, and arthroscopic findings in a single prospective cohort. This study aims to fill this gap and provide clinically applicable correlations that may guide decision-making and prognosis assessment
