This paper presents the early results of a multicenter study of a novel active robotic system for total knee arthroplasty (TKA). The robotic system performs automated milling of bone surfaces, and the study objectives were to assess system safety and effectiveness in a US population.
The multicenter clinical trial followed 115 patients for a minimum of 6-months. Safety was evaluated based on a pre-defined list robot-related adverse events. Efficacy was assessed radiographically comparing planned versus achieved coronal limb alignment.
