Individualized surgery in primary total knee arthroplasty

Total knee arthroplasty (TKA) is a satisfactory procedure for end-stage knee joint pathology. However, there is a significant incidence of unsatisfied patients.In recent years conventional total knee arthroplasty surgical technique has been challenged and a modern trend to respect individual anatomy, alignment and soft tissue laxities has been developed.The indications, limits and outcomes of these modern techniques in selected patients are not well-defined.Modern technology (navigation, patient-specific instrumentation and robotics) has improved accuracy of the osteotomies but their effect on long-term outcomes is still unclear.A technique which respects individual anatomy, laxities and alignment in combination with an implant which is designed to incorporate contemporary knee kinematics, without the use of modern technology, is presented.
