Abstract

Introduction and purpose: An abnormal patellar position has been proven to be associated with anterior knee pain and several other conditions that affect the patellofemoral joint. The purpose of this study was to determine the incidence of patella alta and patella baja and the applicability of the normal range of the Insall-Salvati ratio in the Vietnamese population.

Methodology: Magnetic resonance imaging (MRI) was used to examine 455 Vietnamese subjects' knees. The Insall-Salvati ratio-the ratio of patellar ligament length (LL) and patellar length (PL)-was measured using sagittal T1-weighted images.

Results: The overall mean LL/PL ratio was 1.02 (standard deviation 0.15). No significant differences in the LL/PL ratio were observed between sexes. The frequencies of patella alta (Insall-Salvati ratio >1.32) and patella baja (Insall-Salvati ratio <0.72) were 0.9% and 2.4%, respectively.

Conclusion: The Insall-Salvati ratio is applicable to Vietnamese populations in which high flexion activities such as kneeling and sitting cross-legged are customary. According to our measurement, the normal range of the ratio among Vietnamese subjects was 0.72 to 1.32.

越南人群中安装-萨尔瓦蒂比率的评估:髌骨错位诊断的应用。

简介和目的:异常的髌骨位置已被证明与膝关节前侧疼痛和其他影响髌股关节的疾病有关。本研究的目的是确定上髌骨和下髌骨的发生率以及ininstall - salvati比率正常范围在越南人群中的适用性。方法:采用磁共振成像(MRI)检查455名越南受试者的膝关节。使用矢状面t1加权图像测量Insall-Salvati比率-髌骨韧带长度(LL)与髌骨长度(PL)之比。结果:总平均LL/PL比值为1.02(标准差为0.15)。l /PL比值在两性间无显著差异。上髌骨(Insall-Salvati ratio >1.32)和下髌骨(Insall-Salvati ratio)的频率结论:Insall-Salvati ratio适用于越南人群，该人群习惯跪、盘腿坐等高屈曲活动。根据我们的测量，越南受试者的正常范围为0.72至1.32。
