Prosthesis Types with No or Minimal Use: 2024 Supplementary Report

This report provides summary data and outcomes for hip, knee and shoulder prosthesis types with no or minimal use in Australia. There are two classes of hip replacement no longer used: partial resurfacing and thrust plate. These are defined in the following section on hip replacement. These two classes of implants have not been used since 2014 and 2012, respectively. There are two bearing surfaces used in total conventional hip replacement that have no or little use: procedures performed with ceramic heads on metal bearings and procedures performed with metal heads on ceramic bearings. The rates of revision, reasons for revision and types of revision for procedures using ceramic head/metal bearings are provided. The number of procedures using metal heads/ceramic bearings is very low, so only a summary is provided for this combination. There is one prosthesis type used in total conventional hip replacement that has minimal use: exchangeable neck prostheses. The proportion of procedures using exchangeable necks continues to decline. There are three classes of partial knee replacement that are no longer used: Partial resurfacing, unispacer and bicompartmental. These are defined in the second section of this report on knee replacement. Unispacer and bicompartmental have not been used since 2005 and 2012, respectively. Partial resurfacing is also no longer used with the last procedure recorded in 2022. There is one class of shoulder replacement no longer used: total resurfacing anatomic. This class is defined in the section on shoulder replacement. Total resurfacing anatomic shoulder replacement was last used in 2020.
