Background: Recently, the rate of the Total Knee Replacement (TKR) has been steadily increasing due to its effectiveness in improving patients’ functioning and quality of life, also in reducing the pain. Nevertheless, there are limited population-based data on the frequency and outcomes of total knee replacement. Objective: The aim of this study was to investigate the epidemiologic characteristics and adverse events of patients submitted to TKR so as to conclude the most common indications and risk factors of the surgery. Method: retrospective cohort study had been carried out in King Fahad Hospital in Madinah and Madinah National Hospital, on 65 patients (Male and Female) who already performed total knee replacement and had been interviewed using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results: Majority of the patients were females as 53 (81.5%) while only 12 (18.5%) were males. Out of these numbers, nearly all patients (98.5%) had Osteoarthritis with 93.8% underwent TKR and 50.8% done on the bilateral knee, while one-third of them were distributed on both sides. Majority of them complained about swelling 37 (56.9%) as a post-operative complication. (WOMAC) score revealed a mean of 82.8 with a range from 40.5 to 99.2. More than half of them were satisfied with the surgical operation. This project also has indicated a positive relationship between post-operative complication such as stiffness and move limitation against satisfaction toward surgical operation. Conclusion: Based on our findings even after post-operative complication, most patients were satisfied with the procedure. Therefore, after the operation, surgeons need to remind patients to do a regular visit for a post-operative check-up. Keywords: Total knee replacement, WOMAC, Osteoarthritis, Surgery.
