Metal-on-metal hips fuel elevated revision rates
AUSTRALIAN surgeons are shunning the use of metal-on-metal hip prostheses following the DePuy recall, a world-leading move backed by new data showing higher rates of revision for this class of device.
The Australian Orthopaedic Association (AOA) last week released figures showing the five-year revision rate for DePuy’s recalled ASR metal-on-metal hip was 10.2% compared to 3.5% for rival joints.
In a report of its investigation of patient outcomes, the AOA said that overall, metal-on-metal hip replacement devices had the highest rate of revision compared to any other bearing surface.
Professor Stephen Graves, director of the AOA’s National Joint Replacement Registry, said surgeons had already shifted away from the problematic prostheses.
“We are seeing higher rates of revision from the [metal-on-metal] class as a whole,” Professor Graves said.
“There’s almost no large-hip metal-on-metals being
