Differences Between Traumatic and Degenerative Medial Meniscus Posterior Root Tears: A Systematic Review.

ABSTRACT:

Background

Intact meniscus roots are a prerequisite for normal meniscal function, including even distribution of compressive forces across the knee joint. An injury to the root disrupts the hoop strength of the meniscus and may lead to its extrusion and the development of osteoarthritis. A medial meniscus posterior root tear (MMPRT) is often thought to have a primary degenerative pathogenesis. However, there is mention of some cases of MMPRTs where the patients have a solely traumatic injury to a previously healthy meniscus.

Purpose

To describe a subpopulation of patients with traumatic MMPRT.

Study design

Systematic review; Level of evidence, 5.

Methods

The Web of Science database (www.webofscience.com) was queried using the Medical Subject Headings term "medi
