VELYS robotic-assisted total knee arthroplasty: Enhanced accuracy and comparable early outcomes versus manual instrumentation during adoption.

ABSTRACT:

Purpose

This study assessed the accuracy and early clinical outcomes of the VELYS™ Robotic-Assisted solution for total knee arthroplasty (TKA).

Methods

A multicenter, prospective non-randomized 1:1 cohort study was conducted at five sites. Subjects underwent TKA with either manual instrumentation or with robotic-assistance (RA). RA procedures were the first conducted at each site, therefore, representing the adoption phase for each surgeon. Mechanical alignment was targeted in the manual arm, while the target and technique varied in the RA arm. The primary objective was a non-inferiority (NI) analysis of the accuracy of the hip-knee-ankle (HKA) for RA versus manual, with a 1.5° NI margin. The accuracy of the mechanical medial distal femoral angle (mMDFA), mechanical medial p
