Ceramic Bearings Are Associated With a Significantly Reduced Revision Rate in Primary Hip Arthroplasty: An Analysis From the National Joint Registry for England, Wales, Northern Ireland, and the Isle of Man

Synchrotron-based characterization of arthroprosthetic CoCrMo particles in human bone marrow

“…The release of metallic particles and ions has been reported primarily for total hip arthroplasty (THA) and hip resurfacing (HR) implants with bearing components made of CoCrMo [ 5 – 7 ]. Arthroplasty registry studies of metal-on-metal and metal-on-polyethylene hip implants have indicated worse survival rates of some models, as compared to articular bearings made of alternative materials [ 8 , 9 ]. THA implants with CoCrMo dual modular neck junction (mTHA) have also been associated with formation of particulate and ionic degradation products predominantly by fretting/crevice corrosion [ 10 – 12 ].…”

Lower Rates of Ceramic Femoral Head Use in Non-White Patients in the United States, a National Registry Study

“…Ceramic femoral heads reduce long-term rates of polyethylene wear and taper corrosion compared to metal counterparts and so the effect of disparities in their use will likely take years to become observable [ 42 – 44 ]. A recent registry study of the United Kingdom found significantly lower revision rates at two years for ceramic-on-polyethylene bearings compared to metal-on-polyethylene bearings [ 25 ].…”

“…Ceramic components in THA have become increasingly popular due to their favorable mechanical and tribological properties compared to metal-on-polyethylene or metal-on-metal components [ 21 , 22 ]. Ceramic femoral head use is associated with significantly longer implant survival in a single institution and large registry studies [ 23 – 25 ]. While the use of these components is increasing in parts of the world, cost remains a limiting factor [ 21 , 23 ].…”

CORR Insights®: A Nomogram That Characterizes a Patient’s Odds of Developing Squeaking After Fourth-generation Ceramic-on-ceramic THA

“…Because there are so many variables to consider, and because randomized trials may be too small to tease them out, the best answers may come from registry-based research. One such study recently found an association between the use of CoC and lower rates of revision for all causes, revision for infection, and revision for aseptic causes, supporting ceramic bearings in THA [4]. However, some or all of the observed differences associated with bearing type may have been driven by other factors such as the American Society of Anesthesiologists class and BMI, which could not be included in those multivariate analyses, and future registry studies on this topic must assess those variables carefully, as described by Pitto and Sedel [8].…”
