“…This finding is in line with those of some reported studies, 8,16 although other studies have found sex differences. 9,12,13 This inconsistent findings may be related to ethnic differences, sampling bias or differences in measurement methodology.…”

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.

“…9,10 Studies have shown great variety in patellar morphology among ethnic groups. [10][11][12] Differences in the Insall-Salvati ratio between sexes have also been reported. 9,13 Thus, the widely accepted values of the Insall-Salvati ratio for Western populations may not be applicable in Asian populations.…”

“…It has been reported that the range of the Insall-Salvati ratio is different among races 8 – 10 . Apostolopoulos et al reported that the Insall-Salvati ratio was 0.86 in groups whose daily activities included squatting of the traditional Muslim praying position and was 1.1 in groups who were non-Muslim 9 . It has been reported that the traditional Asian way of living such as sitting straight (Japanese seiza) may impair bone growth at the proximal metaphysis in childhood in the coronal plane, and may induce proximal tibia vara 11 .…”

The positional relationship between patellar and femoral articular surfaces may vary according to the degree of posterior rotation of the tibial condyle, which may influence the patellar configuration. We hypothesized that the configuration of the patella has a rhomboid transformation similar to that of the tibial condyle. This cohort study included 313 patients with knee pain who underwent lateral-view knee digital radiography. The length of the long axis, short axis of the patella, and patellar tendon length of the patellofemoral joint were measured. The patella axis ratio (length of long/short axis) as patellar configuration and Insall-Salvati ratio were calculated. Correlations between the configuration of the tibial condyle and the three length parameters and the Insall-Salvati ratio were assessed. Posterior rotation and the rhomboid transformation of the tibial condyle were positively correlated with the length of the long axis of the patella and negatively correlated with the Insall-Salvati ratio. The more the tibial articular surface shifted posteriorly due to posterior rotation and rhomboid transformation of the tibial condyle, the longer the long axis of the patella was, and the smaller the Insall-Salvati ratio was. The long axis of the patella became longer due to rhomboid transformation, similar to the tibial condyle.
