An Experienced Surgeon Can Meet or Exceed Robotic Accuracy in Manual Unicompartmental Knee Arthroplasty.

Background: Reports in the literature indicate that implant placement is more accurate with robotic-assisted unicompartmental knee arthroplasty (UKA); however, these studies have not always accounted for surgeon experience. The purpose of the present study was to compare the accuracy of tibial component alignment in UKA between an experienced high-volume surgeon and the published data on robotic-assisted surgery.

Methods: The radiographs made before and after 128 consecutive medial UKAs performed manually by a single surgeon using a cemented fixed-bearing implant were reviewed.
