Abstract

Conversion of arthrodesis to total knee arthroplasty (TKA) is technically demanding surgical procedure. In the literature, most cases are treated with stemmed semi-constrained or hinged prostheses. We present a case of a robotic-assisted conversion of arthrodesis to primary TKA (rTKA) in a 35-year-old patient using a non-constrained posterior stabilized implant. At follow-up, the patient reported outcomes improved remarkably with the highest increase for function and activities of daily living and a substantial improvement of health-related quality of life. This article is the first report of robotic-assisted conversion of arthrodesis to TKA using a non-constrained implant, thus it may serve as a proof of concept for the use of robotics for desarthrodesis. Future studies are warranted to investigate the long-term outcomes in a larger patient cohort.
