Hip Replacement

This report analyses 258,333 hip replacements reported to the Registry with a procedure date up to and including 31 December 2009. This is an additional 33,943 hip procedures compared to the number reported last year. When considering all procedures currently recorded by the Registry primary partial hips account for 16.4% of all hip replacements, primary total hips 71.5% and revision hip replacement 12.1% (Table H1).

In 2009, the number of hip replacements reported to the Registry increased by 1,100 (3.4%) compared to 2008. During the last 12 months the use of primary partial increased by 2.2%, primary total by 4.0% and revision hip replacement by 1.1%.

Since 2003, the number of hip replacement procedures has increased by 26.3%. Primary total hip replacement has increased by 32.5%, primary partial 13.6% and revision hip replacement 9.3%. In 2009, primary total hip replacement accounted for 73.5% of all hip replacement procedures. This has increased from 70.1% in 2003. Primary partial hip replacement has decreased from 17.0% in 2003 to 15.3% in 2009 (Figure H1).

Revision hip replacement as a proportion of all hip replacement procedures has declined from 13.0% in 2003 to 11.2% in 2009. This equates to 600 less revision procedures in 2009 compared to what would have been the case if the proportion of revision procedures had not declined from 13.0%.

Public and Private Sector

More than half of all hip replacement procedures reported to the Registry have been undertaken in private hospitals (58.6% in 2009). There were 19,662 private sector hip replacements reported for 2009, an increase of 5.1% compared to 2008. In the public sector, there were 13,918 hip replacements, an increase of 1.0% compared to 2008.

Since 2003, revision hip replacement in the private sector has increased by 10.1% compared to 8.1% in the public sector. This reflects the overall increase of hip replacement surgery in the private sector.
