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).\n\nThe 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.",[69],"Osteoarthritis",[9,15,71,69],"Arthroplasty","2026-05-05",{"date":74,"type":75},"2026-05-08","ACTUAL",{"date":77,"type":75},"2026-01-26",{"date":79,"type":63},"2029-01-26",{"name":5,"class":6},1]
