Tendency of Tibial Component Placement and Short-Term Outcomes in ROSA-Assisted Unicompartmental Knee Arthroplasty Using the Persona Partial Knee System
Medial robot-assisted UKA with this system showed generally accurate component positioning but a consistent tendency toward approximately 2° greater tibial varus and reduced posterior slope relative to the plan. Awareness of this systematic deviation may help optimize tibial placement, and short-term clinical outcomes were favorable.
