Transosseous Fixation with Suspensory Fixation System on Medial Meniscus Root Tears.

Medial meniscal root injury is known to cause an increase in the tibiofemoral contact pressure and results in early osteoarthritis. Several techniques have been described for transosseous suture repair. Typically, the sutures are passed through the meniscus, pulled out through a transtibial tunnel, and tied over a bone bridge, a suture button, or a screw at the anterior tibial cortex. Desired meniscus root tension may not be achieved in transosseous fixation with a suture button. The suspensory fixation technique is aimed to prevent secondary looseness in the knot attached to the button implant in the tibia and to provide the desired tension in the fixation of the button implant in different degrees of flexion of the knee.
