Summary
Total ankle replacement registry data is crucial for evaluating implant outcomes but lags behind hip and knee registries. International data reveal trends in 3-component, mobile-bearing, uncemented prostheses, highlighting the need for U.S. registry development.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Medical Device Technology
Background:
- Joint arthroplasty registries provide unbiased data on implant survivorship and usage.
- Total ankle replacement (TAR) registry data collection and acceptance have lagged behind hip and knee arthroplasty.
- International registries offer valuable insights into TAR outcomes and trends.
Purpose of the Study:
- To identify and analyze worldwide registry data specific to total ankle replacement.
- To determine the types of prostheses used and usage trends over time in TAR.
- To inform future registry development and clinical adoption strategies for TAR in the United States.
Main Methods:
- Electronic search of publications and worldwide registry databanks for TAR information.
- Stratification of identified data into three distinct time periods (2000-2006, 2007-2010, 2011).
- Analysis of prosthesis types and implantation trends from identified TAR systems.
Main Results:
- Worldwide registry data from 33 countries were identified, with detailed TAR information available from only 6.
- Data from 13 TAR systems involving 3,980 ankles were analyzed.
- The vast majority (97%) of reported TARs were 3-component, mobile-bearing, uncemented prostheses.
- Three distinct usage trends were observed: initial rapid adoption followed by decline, minimal use, and sustained growth.
Conclusions:
- International registry data provides critical insights into total ankle replacement trends and prosthesis performance.
- The United States should develop a national joint registry that includes total ankle replacement to learn from global experiences.
- Caution is advised regarding the adoption of new total ankle replacement prostheses, particularly those lacking readily available revision components.
