Biomechanics of medial meniscus tears in the context of pain: a finite element analysis.

ABSTRACT:

Introduction

Meniscal tears represent the most common knee pathology and may be associated with pain. Meniscal pain is caused by direct mechanical stimulation of nociceptors located in the outer, vascular part of the meniscus. Due to difficulties in selecting the optimal surgical treatment, the aim of the study was to analyze the influence of meniscal tears on the stress state in the context of meniscal pain.

Methods

Radial, oblique, longitudinal and horizontal tears involving up to 90% of the width of the medial meniscus were modelled using the finite element method. Two types of knee joint loading were simulated: the stance phase of the gait cycle and external tibial rotation combined with compression.

Results

The highest Tresca equivalent stresses were obtained for
