Purpose : The purpose of this study was to evaluate the arthroscopic findings of the transplanted human allogenic meniscus including MRI changes at follow up. Materials and Methods : From Oct. 1999 to Jun. 2002, nine patients underwent arthroscopic evaluation at follow-up. We used nonirradiated cryopreserved meniscus allograft for 6 cases and fresh-frozen for 3 cases. We used bone-plug method for medial meniscus and bone-bridge method for lateral meniscus to fix the transplanted meniscus. The average follow-up time was 13 months. We evaluated the result by lysholm score, MRI and second-look arthroscopic finding. Results : The second-look arthroscopy after allogenic meniscal transplantation revealed that grafts were well incorporated with surrounding capsular tissue. But one case showed wear on the post horn and the other case which was operated at other local clinic showed tear of the anterior hem due to non-anatomic placement of bone bridge. There was improvement of average Lysholm score form 64 to 87. Conclusion : Second-look arthroscopy revealed excellent incorporation of the allograft with firm attachment and early clinical results are satisfactory. But further studies are necessary to assess whether meniscal transplantation can prevent progressive degenerative changes.
