Project Overview

Tears and avulsion of the posterior meniscus root attachment to the tibia is catastrophic if left untreated. The current standard is arthroscopically-assisted posterior meniscus root repair. This repair is performed by drilling a tunnel through the tibia at the attachment of the posterior meniscus root. This is done using a standard drill guide and guide pin. Sutures are then stitched into the edge of the meniscus using an industry made (Arthrex) multiple use device (Meniscus Scorpion) done through the joint (not through the bone tunnel). Sutures are then retrieved through the tibial tunnel using a suture passing device and then tied over the front of the tibial bone.

However, the medial compartment of the knee and pre-existing arthritic disease associated with posterior meniscus root injury, make suture passage difficult, time consuming, and often associated with iatrogenic cartilage damage. Therefore, the team will design and build a working prototype for a device that would be able to go up the tibial tunnel and pass sutures in the meniscus all-together avoiding the cartilage.
