One risk factor for knee OA is anatomical abnormality (Pes planus). Someone who had pes planus, tend to feel knee pain by 1.39 times and cartilage damage on the inner aspect of the knee joint (medial tibiofemoral compartment) by 1.76 times.The purpose of the research was to investigate the relationship between pes planus with osteoarthritis knee.The Cross sectional design was used in the research, with 30 respondents.pes planus was a free variable, however the osteoarthritis was a dependent variable.The result indicated that there was a relationship between the pes planus with OA knee that was tested with chi square (p = 0.017, RP = 2.2, 95% CI: 1.15-4.26) and BMI with OA knee (p = 0.003, RP = 3, 95% CI: 1.24-7.20). Independent t test, however, displayed that there were differences in SAI value between patients with OA Knee and without OA knee (0.82 ± 0.26 and 0.62 ± 0.23, respectively) with p = 0.047. There is a relationship between pes planus and osteoarthritis knee, with a prevalence ratio is 2.2.
