(vii) Role of Computer Assisted Surgery (CAS) in Training and Outcomes

Repeatability and accuracy of a non-invasive method of measuring internal and external rotation of the tibia

“…Image‐free navigation technology has been validated in acquisition of coronal and sagittal mechanical alignment [43, 44, 47, 60]. In clinical studies, image‐free navigation has been used to determine position of components and limb alignment intra‐operatively, with these parameters being confirmed by post‐operative computed tomography (CT) scanning [9, 10, 15, 20, 29, 38, 39, 56, 58].…”

Current state of the art in total knee arthroplasty computer navigation

“…Over all these years, various articles have also confirmed that knee navigation could improve patient functional outcomes compared to conventional instrumentation [46]. It certainly proves to be a fantastic surgical teaching tool [38, 44]. A major study of the Australian register has more recently shown evidence of reducing significantly the revision rate of TKA after 6 years in patients younger than 65 years and a trend to lesser revisions in older patients as well [17].…”
