Who this trial is looking for
This trial is looking for adults who need knee surgery for osteoarthritis. Participants will have their knee surgery with either robotic help or computer-assisted navigation to see which method offers better results.

Title: Personalized Total Knee Arthroplasty: Computer-Assisted Navigation vs. Robotic Assistance (CAN-ARD).
Summary:
Knee osteoarthritis is frequently treated with Total Knee Arthroplasty (TKA). However, approximately 20% of patients remain dissatisfied following the procedure. This study aims to compare two surgical assistance technologies designed to improve prosthetic placement accuracy: Computer-Assisted Navigation (CAN) and Robotic-Arm Assistance (RA).
The primary objective is to determine if there is a significant difference in functional outcomes and the "forgotten joint" sensation (measured by the Forgotten Joint Score - FJS) between patients operated on with robotic assistance versus those with traditional navigation at 3, 12, and 24 months post-surgery. The study's hypothesis is that there is no major clinical difference between these two techniques when applied within a personalized alignment strategy.
