dc.description.abstractPurpose: Total knee arthroplasty (TKA) is a widely performed surgical procedure for patients with severe knee osteoarthritis, aiming to reduce pain, improve function, and enhance quality of life. Patient satisfaction following TKA typically ranges from 85% to 90%, with factors such as malalignment and postoperative instability being common causes of dissatisfaction. Robotic-assisted TKA (RA-TKA) has demonstrated advantages in surgical precision and better functional recovery compared to conventional techniques. The objective of our study is to evaluate and quantify the level of patient satisfaction and functional outcomes after robotic-assisted TKA. Methods: Prospective cohort of patients who underwent TKA using robotic-assisted surgery at a single centre between 2018 and 2020. Demographic data were collected, and patient satisfaction was evaluated at the 1-year follow-up using the Knee Society Scoring (KSS) system. Functionality was assessed through patient-reported outcome measures (PROMs), specifically the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR), both preoperatively and postoperatively, with a minimum follow-up period of 3 years. All statistical analyses were performed using STATA version 18.5. Results: A total of 270 patients with complete follow-up were evaluated. 92.6% (n = 250) of patients were satisfied or very satisfied with the surgery, while 7.4% (n = 20) reported dissatisfaction. No statistically significant difference was found in age, sex, BMI, or preoperative Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR) between the satisfaction and dissatisfaction groups. However, satisfied patients had a significantly higher postoperative KOOS JR (p = 0.0001). Conclusion: A high level of satisfaction and significant functional improvements were achieved after robotic-assisted TKA in patients with severe osteoarthritis.
