Results: On an average 3.62 per hundred yearly prevalence was found, it increased from 3.31 (2011) to 3.91 (2014). Females were 63%, whereas males were 37%. Among overall prevalent cases, 4.23% were undergone TKA surgeries. Compared to males, odd for females was found at high risk (1.393). Compared to retired population, odd for housewife was found at high risk (1.269) . Conclusions: Study documents four years, prevalence rate of OAK and surgery incidences.
