Introduction:
Knee osteoarthritis is the most common joint disease. The risk factors for knee osteoarthritis are lifestyle, obesity, history of knee injury, sex, and also race. Different race may also have different body habitus, including lower extremity shape, therefore it is important to study the morphometric parameters of the lower extremity. In this study, the morphometric parameters of lower extremity and body mass index in Indonesian Mongoloid population were measured to see their correlation with the presence of symptom of knee osteoarthritis.
Methods:
This study was a cross sectional study. The subjects of this study weremale and female with knee osteoarthritis KL grade 2 or more who agreed toparticipate in this study. From the physical examination, the subjects were then classified into symptomatic and asymptomatic knee osteoarthritis. The lower extremity morphometric parameters that weremeasured in this study: (1) Femoral Valgus Cut Angle (FVCA), (2) Neck Shaft Angle (NSA), (3) Femoral Head Offset (FHO), (4) Trans-Epicondylar Axis (TEA), (5) Tibial Bone Varus Angle (TBVA), and (6) Patellar Morphometry, which were measured by scanogramct scan. Body mass index was measured and classified into normal, overweight, and obese.
Results:
Fifty-eight subjects were included in this study, 38 male and 20 female. From the 58 subjects, 37 had symptomatic knee osteoarthritis and 21 had asymptomatic knee osteoarthritis. An increase in the Neck Shaft Angle (right OR=6.51, p<0.05 and left OR=0.516, p<0.05) had a statistically significant correlation with the presence of symptom ofknee osteoarthritis. While FVCA, FHO, TEA, TBVA, and patellar morphometry did not have significant correlation (p>0,05). The data showed that Femoral Valgus Cut Angle (p<0.05) and Patellar Morphometry (p<0.05) were statistically different in Indonesian Mongoloid male and female with knee osteoarthritis, whereas NSA, FHO, TEA, and TBVA were not statistically different (p>0,05) among male and female of Indonesian Mongoloid Population. Another finding was that BMI had a statistically significant correlation with the presence of symptom ofknee osteoarthritis with a positive and very strong correlation (r=0.776, p<0.05).
Conclusion:
From six lower extremity morphometries in Indonesian Mongoloid population, only Neck shaft angle that had a statistically significant correlation with the presence of knee osteoarthritis symptoms. FVCA and Patellar Morphometry, however, were found to be statistically different between the male and female patients with knee osteoarthritis. BMI also had statistically significant correlation with the presence of symptom in knee osteoarthritis patients of Indonesian Mongoloid population.
