Allograft interference screw fixation in meniscus transplantation.

Abstract

Allograft meniscus transplantation is indicated to restore proper knee biomechanics and prevent subsequent articular degeneration in patients with a meniscus-deficient knee. A variety of techniques for fixation of meniscal transplants exist, with some techniques using soft-tissue fixation of the meniscal horns and others using bony fixation. The authors present a technique of meniscus transplantation using a tibial slot with allograft interference screw fixation. We have had excellent early results with this technique and believe that a cortical allograft interference screw reliably maintains the anatomic position of the meniscal attachments that are critical to the biomechanics and functional outcome of meniscus transplantation.
