Patellar height is the distance formed by the patella and the length of the patellar tendon. Patellar height measurement can predispose to various abnormalities in the knee joint. Patellar height can be measured using several sizes, such as the Insall-Salvati ratio (IS), Modified Insall-Salvati ratio (MIS), Caton-Deschamps index (CD), and the Blackburne-Peel (BP) index. In Indonesia, no data on the value of patellar height is available. This study aims to determine the patellar height value in Indonesians and compare if there are differences with the standard values commonly used by other countries.
This study is descriptive with 136 research subjects aged 20-40. Data were taken from December 2021 to February 2022. The results of patellar X-ray were measured using the Insall-Salvati, Modified Insall-Salvati, Caton-Deschamps, and Blackburne-Peel methods.
In the measurement of patellar height, the longest measurement was found in the MIS measurement, while the shortest patellar height was measured using the BP method. The normal value of the IS method is 0.78-1.26, the MIS method is > 1.98, the CD method is 0.79-1.23, and the BP method is 0.70-1.10 for patellar height in Indonesia. This study also shows no significant difference in the value of patellar height between male and female sex using the IS measurement method.
There is a difference in the standard value of patellar height, which is commonly used by other countries with the standard value of patellar height in Indonesia, but it is not significant.
髌腱长度是髌骨与髌腱长度所形成的距离。髌腱长度测量可能会引发膝关节的各种异常。髌腱长度可以使用多种测量方法，如Insall-Salvati比率（IS）、改良Insall-Salvati比率（MIS）、Caton-Deschamps指数（CD）以及Blackburne-Peel（BP）指数。在印度尼西亚，尚无关于髌腱长度值的数据。本研究旨在确定印度尼西亚人的髌腱长度值，并比较其与其他国家常用标准值是否存在差异。
本研究为描述性研究，有136名年龄在20至40岁之间的研究对象。数据采集时间为2021年12月至2022年2月。使用Insall-Salvati、改良Insall-Salvati、Caton-Deschamps和Blackburne-Peel方法测量髌骨X线检查结果。
在髌腱长度测量中，MIS测量法测得的长度最长，而BP测量法测得的髌腱长度最短。在印度尼西亚，IS测量法的正常髌腱长度值为0.78 - 1.26，MIS测量法为> 1.98，CD测量法为0.79 - 1.23，BP测量法为0.70 - 1.10。本研究还表明，使用IS测量法时，男性和女性的髌腱长度值无显著差异。
其他国家常用的髌腱长度标准值与印度尼西亚的髌腱长度标准值存在差异，但差异不显著。
