Overview of personalized hip arthroplasty
Total hip arthroplasty was developed through two distinct surgical philosophies/approaches: ANATOMICAL (preservation of hip joint' physiology: anatomy, soft-tissue balance, and therefore kinematics) Vs MECHANICAL (implants aligned relative to extra-articular reference plane/axis - no consideration of the native hip' axial anatomy). Hip resurfacing is a great example of a patient specific procedure. Other options are large diameter head (LDH) THA and functional Alignment (FA) techniques. Next decades will serve to compare clinical outcomes/cost effectiveness of those attractive, personalized implantation techniques.
