Meniscal tears treated with partial meniscectomies have been shown to significantly increase contract pressures within the tibiofemoral joint, and a complete focal meniscal deficiency may render the entirety of the meniscus functionally incompetent. Although various techniques of meniscal transplantation have been described, these techniques may require the excision of a considerable amount of healthy meniscal tissue. Furthermore, failures continue to frequently occur. Therefore, attempts to restoring normal knee kinematics and biomechanical forces are essential. Segmental meniscus allograft transplantations may offer the advantage of a robust repair by both maintaining knee biomechanics and biology while maximizing preservation of native meniscal tissue. Also, most meniscal deficiency involves only a portion of the meniscus, and thus we developed this technique to segmentally transplant only the deficient portion. The purpose of this Technical Note is to describe a technique of segmental medial meniscus allograft transplantation in a patient with focal medial meniscus deficiency.
已证实，接受部分半月板切除术治疗的半月板撕裂会显著增加胫股关节内的接触压力，而完全性局灶性半月板缺损可能会使整个半月板功能丧失。尽管已描述了多种半月板移植技术，但这些技术可能需要切除大量健康的半月板组织。此外，失败情况仍频繁发生。因此，恢复正常膝关节运动学和生物力学力量的尝试至关重要。节段性半月板同种异体移植可能具有强大修复的优势，既能维持膝关节生物力学和生物学特性，又能最大程度保留天然半月板组织。此外，大多数半月板缺损仅累及半月板的一部分，因此我们开发了这种仅节段性移植缺损部分的技术。本技术说明的目的是描述在一名患有局灶性内侧半月板缺损患者中进行节段性内侧半月板同种异体移植的技术。
