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.
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.
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.
拉出缝线、缝线锚钉和开放楔形高位胫骨截骨术已广泛用于内侧半月板后根撕裂的手术治疗，并且已有相对较好的临床结果报道。然而，影像学和关节镜检查结果并不充分。据我们所知，本报告描述了首例针对伴有膝内翻的内侧半月板后根撕裂进行内侧半月板后根重建及高位胫骨截骨术的病例。
一名78岁的日本男性因右腘窝疼痛转诊至我院。X线平片显示右下肢机械轴百分比为17%，提示机械轴内翻。磁共振成像检查发现内侧半月板后根撕裂。遂行内侧半月板后根重建及高位胫骨截骨术。其膝关节损伤和骨关节炎评分从术前的22分提高到术后1年的91分。移植物具有良好的活诱导作用，内侧半月板环得以维持。
据我们所知，本报告是首例针对伴有膝内翻的内侧半月板后根撕裂进行内侧半月板后根重建及高位胫骨截骨术的病例。这种手术技术可能对伴有膝内翻的半月板后根撕裂有用。
