Description of intervention(s) / exposure
The ROSA Knee System is a stereotaxic instrumentation system for total knee replacement surgery. The system is used by the surgeon to assist the surgeon in providing software-defined spatial boundaries for orientation and reference information to identifiable anatomical structures for the accurate placement of knee implant components.
