Medial Meniscus Posterior Root Reconstruction and Open- Wedge High Tibial Osteotomy for Medial Meniscus Posterior Root Tear with Varus Knee: A Case Report

INTRODUCTION: Pull-out suture, suture anchor, and open- wedge high tibial osteotomy have been widely used for surgical treatment of medial meniscus posterior root tear, and relatively good clinical results have been reported. However, radiologic and arthroscopic findings are not sufficient. This report describes the first case, to the best of our knowledge, of medial meniscus posterior root reconstruction and high tibial osteotomy for medial meniscus posterior root tear with varus knee. CASE REPORT: A 78-year-old Japanese man was referred to our hospital due to the right popliteal pain. Plain radiography showed the mechanical axis percentage of the right limb to be 17%, indicating a varus mechanical axis. magnetic Magnetic resonance imaging noted a medial meniscus posterior root tear. Medial meniscus posterior root reconstruction and high tibial osteotomy were performed. His knee injury and osteoarthritis score improved from 22 points preoperatively to 91 points 1 year postoperatively. The graft had a good live induction and the medial meniscus hoop was maintained. CONCLUSION: This report is the first case, to the best of our knowledge, of medial meniscus posterior root reconstruction and high tibial osteotomy for medial meniscus posterior root tear with varus knee. This type surgical technique may be useful for a meniscus posterior root tear with varus knee.
