What is it about?
This article describes the consequences of a nonanatomic posteromedial meniscus root repair on the joint loading and contact forces after a meniscus root repair.

Why is it important?
This is a very important subject. This award-winning paper was performed after several patients were sent to us who had meniscus root repairs that healed, but the root repair was put in the wrong position. When a meniscus root tears on the medial side, the meniscus tends to extrude posteromedially and get caught in scar tissue. If one repairs the meniscus directly at that location, we found in this study that it does not restore the normal joint contact loading and it can lead to arthritis. Thus, we demonstrated that the meniscus should be released from scar tissue and pulled back into its normal anatomic position to perform a repair, to restore the joint contact and loading profile
Perspectives
We found this to be a very important study. This is because patients were being sent to us who had meniscus root repairs that did not work. We found the reason they did not work is because the meniscus was not released from scar tissue and pulled back into an anatomic position. As such, the meniscal root repair was ineffective because the meniscus was still extruded outside the joint and the meniscus was not able to function normally.
