Description
【Objective】The transition from the robotic-assisted system NAVIO to its successor, CORI, has led to various improvements, including increased camera d handpiece recognition speed, enhanced drill torque power, and improved bar shapes. In light of these enhancements, this study aimed to investigate how the operation time was affected.
【Methods】The operation times for 119 knees (48 UKAs, 30 BCSs, 41 BCRs) using NAVIO and 63 knees (16 UKAs, 22 BCSs, 25 BCRs) using CORI were measured. Additionally, the operation time was divided into eight phases: Phase 1: Deployment time, Phase 2: Setup time, Phase 3: Registration time, Phase 4: Planning time, Phase 5: Bone cutting time, Phase 6: Trial time, Phase 7: Implant placement time, Phase 8: Closure time. The time spent on each of these phases was examined to investigate how the operation time changed with the transition from NAVIO to CORI. Statistical analysis was performed using t-tests.
【Results】The transition from NAVIO to CORI resulted in a reduction in total operation time: 106 minutes to 94 minutes for UKA, 125 minutes to 114 minutes for BCS, and 127 minutes to 103 minutes for BCR. When broken down by phase, significant (p<0.05) reductions in operation time were observed in phase 3 and phase 5 out of the eight phases.
【Discussion】The transition from NAVIO to CORI improved camera and handpiece response times, allowing for faster registration. Additionally, the enhancements in drill torque power and bar shape led to quicker bone cutting, resulting in a 10 to 20-minute reduction in operation time.
【Conclusion】The transition from NAVIO to CORI led to reductions in registration and bone cutting times, contributing to the overall reduction in operation time
