INTRODUCTION Data presented in this report have been submitted to the Registry by both public and private hospitals. Currently this involves 305 hospitals nationally but varies from time to time due to hospital closures, new hospitals or changes to services within hospitals. The Registry was implemented in a staged manner on a state-by-state basis. Implementation was completed
Table S1
All hip replacement procedures recorded by the Registry from the commencement date to the 31 December 2014 have been included in this report. Table S1 shows the commencement date for each state/territory.

HIP REPLACEMENT Categories of Hip Replacement The Registry groups hip replacement into three broad categories, primary partial, primary total and revision hip replacement.
and thrust plate. Definitions for each of these are detailed in the relevant chapters. Revision hips are re-operations of previous hip replacements where one or more of the prosthetic components are replaced, removed, or another component is added. Revisions include re-operations of primary partial, primary total or previous revision procedures.
A primary replacement is the initial replacement procedure undertaken on a joint and involves replacing either part (partial) or all (total) of the articular surface. Primary partial and primary total hip replacement are further sub-categorised into classes depending on the type of prostheses used. Partial hip classes are partial resurfacing, unipolar monoblock, unipolar modular and bipolar. Total hip classes are resurfacing, conventional
Hip revisions are sub-categorised into three classes, major total, major partial or minor revisions. These are defined in the chapter on revision outcomes.
