This application is directed toward a quantitative high precision acetabular machining system designed to enable accurate and precise positioning of acetabular resurfacing implants, or the like bone socket resurfacing devices, in a manner which eliminates malpositioning, loss of center, drift and inappropriate depth calculations. Subsequent to site preparation, a precision implant is disclosed which provides for resurfacing of damaged articular cartilage with bone preserving and non-drift instrumentation utilizing synthetic materials in an anatomically correct fashion to maintain excellent hip stability while maintaining an accurate hip joint center mated with anatomic femoral head sizes.
