摘要

The objective of this study was to analyze the postoperative results of patients who underwent cTKA compared to those who underwent robot-assisted total knee arthroplasty (raTKA). A retrospective analysis was conducted on patients who underwent primary TKA. Patients were classified into two groups based on prosthesis type. Functional outcomes were assessed using the Forgotten Joint Score (FJS). Statistical analysis included multiple linear regression to identify predictors of joint awareness. A total of 181 patients were analyzed (raTKA group: n = 90; cTKA group: n = 91). FJS scores were significantly higher in the raTKA group (72.5 [54.1–100]) than in the cTKA group (61.8 [39.6–91.7]; p = 0.004). Regression analysis identified the male sex (coef. = 11.50, p = 0.005) as a positive predictor of FJS, while cTKA group was associated with lower scores (coef. = − 9.09, p = 0.026). Body mass index showed no significant association with FJS (coef. = 0.65, p = 0.214). Surgery type and sex influence joint awareness after TKA. Male patients and those undergoing robotic-assisted TKA demonstrated superior functional perception.
