Abstract：
UNASSIGNED: Meniscal root tears are defined as soft-tissue and/or osseous injuries that rip or avulse within one centimeter of the meniscal insertion to the tibial plateau. These injuries impact around 100,000 patients a year and make up 10 % to 21 % of all meniscal tears. Meniscal extrusion frequently happens when there are root rips, and the transmission of circumferential hoop loads is hampered.
METHODS: We present one case of a 28-year-old male who complained of pain and stiffness in his left knee since 2 years after undergoing ACL reconstruction using a hamstring autograft. His examination revealed joint line tenderness on both the medial and lateral sides of the left knee. Further investigations involving X-ray and MRI established the diagnosis of both medial and lateral meniscal root tears, which were surgically managed using the transtibial pullout technique.
CONCLUSIONS: The biomechanical implications of meniscal root tears, such as loss of hoop forces and increased tibiofemoral contact pressures, underscore the importance of timely diagnosis and management. The literature advocates surgical treatment for managing root tears, as leaving them without surgical intervention can lead to functional outcomes similar to those of total meniscectomy.
CONCLUSIONS: This case report presents both menisci posterior root tears with an intact ACL graft which is unique in that they commonly tear in conjuction with ACL. These kind of injuries necessitates prompt diagnosis and surgical intervention to protect the knee from early arthritic changes.

摘要：
■半月板根部撕裂定义为在半月板插入胫骨平台一厘米内撕裂或撕破的软组织和/或骨损伤。这些损伤每年影响约100,000名患者，占所有半月板撕裂的10％至21％。当根裂时，半月板挤压经常发生，周向环向载荷的传递受到阻碍。
方法：我们介绍了一例28岁男性患者，他在使用自体腿筋进行ACL重建后2年来一直抱怨左膝疼痛和僵硬。他的检查显示左膝盖内侧和外侧的关节线压痛。涉及X射线和MRI的进一步研究确定了内侧和外侧半月板根部撕裂的诊断，使用经胫骨拔出技术进行手术治疗。
结论：半月板根部撕裂的生物力学意义，例如环向力的损失和胫骨股接触压力的增加，强调及时诊断和管理的重要性。文献提倡手术治疗根裂，由于不进行手术干预可导致与全半月板切除术相似的功能结局。
结论：本病例报告显示了半月板后根撕裂与完整的ACL移植物，其独特之处在于它们通常与ACL结合撕裂。这些类型的损伤需要及时诊断和手术干预，以保护膝关节免受早期关节炎的影响。
