Total hip arthroplasty statistics, devices, and revisions

Selection of the most suitable implant is a critical component of providing high quality hip arthroplasty care. Since revision is an undesirable outcome and is widely reported across arthroplasty registries, we include a chapter on revision risk. These data are based on primary cases performed from 2/15/2015 to 12/31/2016. For detailed information on each figure and table (date ranges and inclusion/exclusion criteria), see the online supplement wp-content/uploads/2017/10/MARCQI_2012-2016_report_chapter_4_and_5_specifications.pdf. Apparent inconsistencies in sample sizes between tables can be resolved by examining the inclusion criteria listed for each table in the online supplement. The first section provides an overview of THA, primary and revision procedures combined. All revision risk in sections two through four are for primary conventional THA only.
