Key Takeaways: 35% relative reduction in early revision rates
The survivorship reported within the AOANJRR of Persona® Knee implants combined with early data from the ROSA Knee System is promising. The CPR for Persona Knee CR and PS bearings is 1.9 (95% CI, 1.6 – 2.2) at five years, compared to a CPR of 3.4 (95% CI, 3.4-3.5) for the same follow-up time with all other total knees. The revisions/100 observation years was 0.39 (95% CI, 0.14 – 0.86) for robotic assisted TKA using the Persona knee compared to 0.60 (95% CI, 0.52– 0.68) without robotic assistance for the same implants. This demonstrates a relative reduction in revisions of 35% when robotic assistance was used.
