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.
