Meniscus allograft transplantation (MAT) has yielded excellent long-term functional outcomes when performed in properly indicated patients. When evaluating a patient for potential MAT, it is imperative to evaluate past medical history and past surgical procedures. The ideal MAT candidate is a chronologically and physiologically young patient (<50 years) with symptomatic meniscal deficiency. Existing pathology in the knee needs to be carefully considered and issues such as malalignment, cartilage defects, and/or ligamentous instability may require a staged or concomitant procedure. Once an ideal candidate is identified, graft selection and preparation are critical steps to ensure a proper fit and long-term viability of the meniscus. When selecting the graft, accurate measurements must be taken, and this is most commonly performed using plain radiographs for this. Graft fixation can be accomplished by placing vertical mattress sutures and tying those down with the knee in full extension.
同种异体半月板移植（MAT）在适选患者中进行时已产生了出色的长期功能结果。在评估患者是否适合进行MAT时，评估既往病史和既往手术情况至关重要。理想的MAT候选者是年龄在时间和生理上均较年轻（<50岁）且有半月板缺损症状的患者。膝关节现有的病变需要仔细考虑，诸如对线不良、软骨缺损和/或韧带不稳定等问题可能需要分期或同期手术。一旦确定了理想的候选者，移植物的选择和准备是确保半月板合适匹配和长期存活的关键步骤。选择移植物时，必须进行准确测量，最常用的方法是通过普通X线片进行测量。移植物固定可通过放置垂直褥式缝线并在膝关节完全伸直时将其系紧来完成。
