INTRODUCTION
The menisci are responsible for several functions. They are shock absorbers during dynamic loading on the knee and provide a broader surface area on which to distribute stress evenly to the tibia and femur. These functions allow for smoother movement and greater stability of the knee joint. Meniscal injury can be a great impediment to the function of the knee. Therefore, in the case of meniscal injury, our main concern is the relief of patient symptoms, followed by consequent restoration of meniscal function to the greatest of our ability. To prevent the long terms effects of a meniscectomy, meniscal allograft transplantation (MAT) was developed. The potential of using the size of the contralateral healthy menisci, to determine the size of the menisci to be replaced, will be discussed.
METHODS
Knee MRIs done on healthy patients in the past 5 years were reviewed. Magnetic Resonance Imaging was performed using a 3-T scanner. Each individual was examined with knee joints in full extension. Measurements were performed two separate times, two weeks apart. A mean of three measurements was made during each session to reduce error. Thirty-eight normal bilateral knee joints MRIs remained (16 males, 22 females). Participants were sampled from the institutional Picture Archiving and Communication System (PACS). Age, gender, and the medial meniscal and lateral meniscal size of both knees were recorded. The laterality of the menisci was compared between both knees in each patient.
RESULTS
A total of 38 patients were included in this study, with a mean age of 37.39 (±9.50) years. They were 16 (42.1%) men and 22 (57.9%) women. We didn't find any significant difference in the mid-coronal section between left and right knees meniscal measurements. None of the measurements were significantly different between men and women. There was no significant difference in the medial mid-sagittal section or lateral mid-sagittal section between left and right knee meniscal measurements.
CONCLUSION
The results obtained in this study may support the use of MRI of the bilateral knee to obtain an appropriately sized allograft.

使用磁共振成像确定健康志愿者中半月板大小的偏侧性。
简介半月板负责多种功能。它们是膝盖动态负荷过程中的减震器，并提供了更大的表面积，可将应力均匀地分布到胫骨和股骨上。这些功能可以使膝关节运动更平稳，稳定性更高。半月板损伤可能是膝盖功能的很大障碍。因此，在半月板损伤的情况下，我们主要关注的是减轻患者症状，随后最大程度地恢复半月板功能。为了防止半月板切除术的长期影响，开发了半月形同种异体移植（MAT）。将讨论使用对侧健康半月板的大小来确定要更换的半月板的大小的潜力。方法回顾了过去5年中对健康患者进行的膝部MRI检查。磁共振成像是使用3-T扫描仪进行的。检查每个人的膝关节是否完全伸展。测量分别进行两次，相隔两周。为了减少误差，每个会话期间平均进行了三个测量。保留了38例正常的双侧膝关节MRI（男16例，女22例）。参与者来自机构的图片存档和通信系统（PACS）。记录双膝的年龄，性别以及半月板的内侧半月板和外侧半月板大小。比较每个患者双膝之间半月板的偏斜度。结果本研究共纳入38例患者，平均年龄为37.39（±9.50）岁。他们是16名男性（42.1％）和22名女性（57.9％）。我们没有 在左半月板和右半月板的半月板测量中未发现冠状动脉中段有任何显着差异。男女之间的测量值均无显着差异。左右半月板半月板测量在内侧中矢状切面或外侧中矢状切面之间没有显着差异。结论在这项研究中获得的结果可能支持使用双侧膝关节MRI来获得适当大小的同种异体移植物。
