abstract
Title: Graft Extrusion in Open vs Arthroscopic Meniscus Transplantation: A 1 Year Comparative Study of 39 patients. Purpose: to evaluate the radial displacement of meniscal allograft transplants (MATs) in patients operated with an open technique vs. an arthroscopic technique at 1 year postoperatively. Radial displacement or extrusion of the graft is frequently observed after meniscus transplantation. The hypothesis is that arthroscopically inserted MATs extrude less than open MATs and therefore have a more intra-articular position than open surgery transplants. Materials and Methods: 39 patients were included in the study: the first group of open surgery transplants consisted of 16 patients (10 lateral, 6 medial). The second group of arthroscopic transplants consisted of 21 patients (14 lateral, 7 medial). MR-images were taken one year post-surgery. The displacement, evaluated on 1,5T MR coronal images, was defined as the distance between the tibial plateau and the outer edge of the meniscus. Results: The radial displacement of lateral open surgery transplants (mean= 4,04 mm; SD= 1,46) is significantly larger (p < 0,05) than the displacement of arthroscopically implanted MATs (mean= 3,38 mm; SD= 0,85). The external displacement of medial open surgery transplants (mean= 4,71 mm; SD= 0,97) is significantly larger (p < 0,05) than the displacement of arthroscopically implanted MATs (mean= 2,36 mm; SD= 0,89). Conclusion: Graft position is influenced by the surgical technique; the radial displacement of arthroscopically implanted MATs is, both lateral and medial, significantly less than meniscal transplants implanted by open surgery. The clinical relevance remains to be determined.
