The 5 principles to perform restricted kinematic alignment total knee arthroplasty
Dr Pascal-André Vendittoli is a professor of surgery at University of Montreal, Canada who performs kinematic alignment TKA since 2011. He proposed the “restricted” kinematic alignment protocol (rKA) to reliably produce a prosthetic knee with component/knee/limb alignments that always fall within an evidence-based safe alignment range which is compatible with long term implant survivorship. In the current video, he is presenting the scientific bases for this surgical technique. He will describe the five principles to perform rKA successfully.
