INTRAOPERATIVE ASSESSMENT OF COMPONENTS IN NAVIGATED KNEE ARTHROPLASTY IN THE ELDERLY.

OBJECTIVE: This study aims to evaluate the sizing and positioning of femoral and tibial components in Primary Total Knee Arthroplasty (TKA) procedures conducted at the Instituto Ortopédico de Goiânia (IOG), Goiânia, Goiás Brazil. METHODOLOGY: Elderly patients undergoing primary TKA with the use of SCORE® prostheses and the Amplivision Navigation System were included in the study. The size and positioning of the femoral and tibial components were analyzed. Data collection was performed using the Amplivision system and statistical analysis was conducted using Minitab21 software. The study was approved by the Ethics Committee and is in accordance with the Brazilian General Data Protection Law (LGPD). RESULTS: All patients received the SCORE® prosthesis, with a higher prevalence of procedures on the right knee (60%). No statistically significant differences were observed in the positioning of femoral and tibial components. CONCLUSION: Surgical navigation proved to be effective in optimizing the sizing and positioning of implants, contributing to the technical quality of the procedure and the durability of prosthetic components. Level of Evidence: III, Cross-Sectional Observational Study.
