In this video, Dr Vendittoli reviews the normal knee anatomy and kinematics and the modifications produced by the “one size fits all” mechanical alignment technique. As a solution to improve our TKA patients’ clinical results, Dr Vendittoli present the “restricted” kinematic alignment protocol (rKA). He developed this protocol 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.
