NCT06969222

Brief Summary

This is a prospective trial that attempts to develop evidence on the safety and performance of RA-TKA (Robotic-assisted total knee arthroplasty) with Skywalker and eMP (Evolution Medial Pivot) knee. Moreover to evaluate performance of eMP patients with Skywalker (in comparison to eMP with conventional instrumentations and non-MP TKAs)
