Background: The percentage of knee osteoarthritis incidence in Indonesia is quite high. In addition, most cases of knee osteoarthritis patients are performed Total Knee Replacement (TKR). Besides the effectiveness of TKR surgery to overcome the knee osteoarthritis, previous studies showed that almost a third patients reported unfavourable pain outcomes at between 3 months and 5 years after TKR surgery. So, this study aims to evaluate the functional outcome of patients after performed TKR at Prof Dr R.D. Kandou Manado Hospital during January-December 2018 period. Methods: A cross sectional study was carried out among 32 patients who underwent TKR at Prof Dr R.D. Kandou Manado during the study period. Before surgery and 3-month post-surgery, all of patients were evaluated with Knee Society Score questionnaire. The collected data that consisted of knee score and knee function score by American Knee Society Score (AKS), as well as data demographics of respondents, were analyzed with paired T-test using SPSS version 23 for Windows. Results: Most of the patients are in the elderly category of age (≥60 years old) (78.13%) and this disease showed a higher prevalence in women (78.13%) than in men (21.87%). Patients showed a significant improvement in the degree of knee function (p<0,0001) at 3-months after surgery compared to before surgery. Moreover, as many as 21,87% of patients still experience pain 3-months after TKR. Conclusions: A significant improvement was found among patients in the degree of knee function after TKR. However, several patients still experience pain at follow up 3 months after TKR.
