As patella height can affect the outcome of total knee arthroplasty (TKA) in a number of ways, this study aimed to investigate whether factors such as region, sex and age play a role in causing differences in patella height.
Between the 1st of March and the 31st of December 2022, 2000 patients from 7 different countries (Turkey, Saudi Arabia, Germany, Austria, Italy, Spain, and the United Kingdom) awaiting elective TKA were enrolled in this study. Lateral radiographs of the knee with the femoral condyles fully overlapped were used to measure the Insall-Salvati index. The patella height measurements were then correlated with age, sex and region to see if there were any patterns of distribution.
From ten different hospitals across seven countries, 2,000 patients were collected. Approximately, 50% of the groups were female and 50% were male with a median age at surgery of 59 years (± 20 years). There were no significant differences in patella position based on age, region or sex between the different study populations, although there were significant differences between patients from different countries.
Patella height showed significant variability within our patient cohort, even between different populations within the same country of origin. However, it should be noted that age, sex and country of origin do not appear to influence patella height in the preoperative planning of knee surgery.
由于髌骨高度可通过多种方式影响全膝关节置换术（TKA）的结果，本研究旨在调查地区、性别和年龄等因素是否在导致髌骨高度差异方面起作用。
在2022年3月1日至12月31日期间，本研究纳入了来自7个不同国家（土耳其、沙特阿拉伯、德国、奥地利、意大利、西班牙和英国）等待择期TKA的2000名患者。使用股骨髁完全重叠的膝关节侧位X线片测量Insall-Salvati指数。然后将髌骨高度测量值与年龄、性别和地区进行关联，以查看是否存在任何分布模式。
从七个国家的十家不同医院收集了2000名患者。大约50%的组为女性，50%为男性，手术时的中位年龄为59岁（±20岁）。不同研究人群之间，基于年龄、地区或性别的髌骨位置没有显著差异，尽管来自不同国家的患者之间存在显著差异。
在我们的患者队列中，髌骨高度显示出显著的变异性，即使在同一原籍国的不同人群之间也是如此。然而，应该注意的是，在膝关节手术的术前规划中，年龄、性别和原籍国似乎不会影响髌骨高度。
