Outcomes of Meniscus Root Repair Using a Transtibial Pullout Technique

Launched by MAYO CLINIC · Jan 27, 2017

ClinConnect Summary

The loss of attachment at the root of the meniscus impairs the ability to maintain hoop strain when the tibiofemoral joint is loaded. This loss of hoop strain is responsible for the increased pressure on the articular cartilage.

This new awareness has prompted surgeons to consider surgical repair for treatment of meniscal root avulsions. Despite this recent focus on results of surgical repair, prospective studies are lacking, and the optimal surgical indications and technique have not been optimized.
