Summary of 2016 AOANJIRR Report by Patricia Walter

PRIMARY TOTAL RESURFACING HIP REPLACEMENT

The Registry has recorded 8,895 total resurfacing hip replacement procedures in patients less than 55 years of age. In this age group, the use of primary total hip resurfacing as a proportion of primary total hip procedures, has declined from a peak of 30.2% in 2004 to 4.3% in 2015. There were 93.1% of patients who had a total resurfacing hip replacement performed for osteoarthritis, compared to 97.8 % for the older age groups. The cumulative percent revision at 15 years for total resurfacing hip replacement for patients less than 55 years of age with a primary diagnosis of osteoarthritis was 13.2% . There was a higher rate of revision for females and for head sizes less than 50mm in this younger age group.

There were 11 primary total resurfacing hip replacement prosthesis combinations recorded by the Registry in patients less than 55 years of age, used with 10 or more procedures. “There was a higher rate of revision for females and for head sizes less than 50mm in this younger age group.”

As the BHR and the Adept are the only resurfacing devices used in 2015, we have performed a separate analysis combining these two prostheses. The cumulative percent revision at 15 years for the BHR and Adept combined is 9.5% . Females had a higher rate of revision. At 10 years the cumulative percent revision for females is 14.5% compared to 3.7% for males.
