Meniscus root tears are important to recognize early given their potentially devastating consequences on joint health. This injury results in the lost ability of the meniscus to transfer axial loads into hoop stress; therefore, it is functionally equivalent to a complete meniscectomy. This causes rapid progression of osteoarthritis and increased need to total knee arthroplasty in a previously healthy joint. Despite these consequences, root tears have only been discussed in the orthopedic literature in the last 10 to 15 years and have not been routinely integrated into nonoperative sports medicine education. It is important for all nonoperative sports medicine providers to properly diagnose and triage this injury early in its course to maximize joint preservation efforts. The goal of this manuscript is to review the anatomy, presentation, natural history, imaging, and treatment options for meniscal root tears.
半月板根部撕裂因其对关节健康可能产生毁灭性的后果而需要及早识别。这种损伤导致半月板丧失了将轴向负荷转化为环向应力的能力；因此，它在功能上相当于完全半月板切除术。这会导致先前健康的关节中骨关节炎迅速进展和全膝关节置换术的需求增加。尽管存在这些后果，但根部撕裂仅在过去 10 到 15 年的骨科文献中进行了讨论，并且尚未常规纳入非手术运动医学教育中。对于所有非手术运动医学提供者来说，重要的是在其病程早期正确诊断和分诊这种损伤，以最大程度地保留关节。本文的目的是回顾半月板根部撕裂的解剖、表现、自然病史、影像学和治疗选择。
