Meniscal root tears typically result from a hyperflexion/squatting injury or are in conjunction with ligamentous knee injury. Once a complete tear occurs, the meniscus is unable to convert axial loads to transverse hoop stresses which result in increased tibiofemoral contact pressure and osteoarthritis. The goal of a meniscal root repair is to anatomically reattach the meniscal root to the tibia plateau. Complete and partial healing occurs in over 93% of cases with retear rates ranging from 0% to 7%.
We present a case of a highly active 21-year-old male collegiate soccer play that sustained a medial meniscal root tear after slipping on ice.
An anatomic medial meniscal root repair was performed using a transtibial guide and 2 loop sutures tied over a button.
Full anatomic footprint coverage was able to be achieved intraoperatively and gentle range of motion from 0 to 90° of flexion did not result in gap formation.
DISCUSSION/CONCLUSION: Successful outcomes with full anatomic footprint coverage of the medial meniscal root can be achieved with 2-loop suture button configuration.
半月板根部撕裂通常由过度屈曲/蹲姿损伤引起，或与膝关节韧带损伤相关。一旦发生完全撕裂，半月板就无法将轴向负荷转化为横向环向应力，这会导致胫股关节接触压力增加和骨关节炎。半月板根部修复的目标是将半月板根部解剖复位至胫骨平台。超过93%的病例实现了完全或部分愈合，再撕裂率在0%至7%之间。
我们报告一例21岁的男性大学足球运动员，他在冰上滑倒后导致内侧半月板根部撕裂。
采用经胫骨导向器和2根套索缝线，在纽扣上打结，进行解剖学内侧半月板根部修复。
术中实现了完全解剖覆盖，从0至90°的轻柔屈曲活动范围未导致间隙形成。
讨论/结论：采用2根套索缝线纽扣构型可成功实现内侧半月板根部完全解剖覆盖的良好结果。
