Robotic‑assisted total knee arthroplasty is comparable to conventional total knee arthroplasty: a meta‑analysis and systematic review James Randolph Onggo1 · Jason Derry Onggo1,2 · Richard De Steiger3 · Raphael Hau1,4,5,6 Received: 29 October 2019 © Springer-Verlag GmbH Germany, part of Springer Nature 2020
Abstract Background Total knee arthroplasty (TKA) is a successful procedure in managing end-stage arthritis when non-operative treatments fail. New technologies such as robotic TKA (rTKA) have been developed to improve the accuracy of prosthesis implantation. While short-term cohort studies on rTKA have shown excellent results, the evidence comparing between rTKA and conventional TKA (cTKA) is not yet well established. This meta-analysis aims to compare the efficacy and safety of rTKA versus cTKA in terms of clinical outcomes, radiographic results, complications, peri-operative parameters and costs. Methods A multi-database search was performed according to PRISMA guidelines. Data from studies comparing between rTKA and cTKA were extracted and analyzed. Results Eighteen studies were included in this review, consisting of 2234 rTKA and 4300 cTKA. Robotic TKA led to a more precise prosthesis implantation with significantly fewer outliers in the mechanical axis (p
