Historically, intraoperative analysis of knee fracture procedures relied upon a fluoroscopic reduction assessment by the surgeon. This is a subjective assessment due to the lack of linear measurement reference data. Compared with the knee, the ankle and wrist have well-established bony anatomical relationships to guide reduction assessment during fracture treatment. The purpose of this study was to (1) determine the width ratios in the knee (plateau to femur) with aging, and (2) determine knee width changes with aging. One-hundred and fifty consecutive uninjured knee radiographs were reviewed. In all age groups, the width ratio of the articular distal femoral (ADF) to the articular tibial plateau (ATP) is greater than 1.0 and between 1.03 and 1.05. The tibia plateau width is on average 9.34 mm wider and the femoral width is 8.0 mm wider in the 61 to 80 age group than the ATP and the ADF in the younger age groups. In conclusion, the articular tibial plateau width and the articular distal femoral width are nearly equal across ages 20 to 80 years. An absolute articular width value by age cannot be assigned because articular widths change with aging.
从历史上看，膝关节骨折手术的术中分析依赖于外科医生的透视复位评估。由于缺乏线性测量参考数据，这是一种主观评估。与膝关节相比，踝关节和腕关节具有成熟的骨性解剖关系，可在骨折治疗过程中指导复位评估。本研究的目的是：（1）确定膝关节（平台到股骨）随年龄增长的宽度比，以及（2）确定膝关节随年龄增长的宽度变化。回顾了 150 例连续的无损伤膝关节 X 光片。在所有年龄组中，关节远端股骨（ADF）与关节胫骨平台（ATP）的宽度比均大于 1.0，介于 1.03 和 1.05 之间。与年轻年龄组的 ATP 和 ADF 相比，61 至 80 岁年龄组的胫骨平台宽度平均宽 9.34 毫米，股骨宽度宽 8.0 毫米。总之，在 20 至 80 岁之间，关节胫骨平台的宽度和关节远端股骨的宽度几乎相等。由于关节宽度随年龄变化，因此不能按年龄分配绝对关节宽度值。
