Ongoing concerns about metal-on-metal hip bearings have continued with the issue of a UK MHRA alert about the combination of the Stryker Mitch large metal-on-metal bearing with the Accolade stem. Analysis of the England and Wales National Joint Registry data has demonstrated a revision rate of 8.8% at 4 years for all Mitch/femoral stem combinations which is higher than the NICE benchmark. Interestingly, revision rates with the uncemented Accolade stem were substantially worse than with the cemented Exeter stem (4 year revision rate 10.7% compared with 3.7%).
The Mitch resurfacing has a lower revision rate of 3.1% at 4 years, which is in line with NICE guidance.
The Mitch bearing is manufactured by Finsbury Orthopaedics, which was acquired by DePuy in 2009.
