Our goals are to provide an online reference and education about the peer-reviewed literature for ceramic biomaterials used in total joint replacements and to stimulate hypothesis-driven research in applications of ceramic biomaterials. The focus of the site is to summarize the clinical performance of medical grade ceramic and ceramic implants.READ MORE ABOUT OUR SITE

The purpose of this study was to analyze the utilization and outcomes of ceramic bearings used in revision total hip arthroplasty (R-THA) in the Medicare population. A total of 31,809 patients aged >65 years at the time of revision surgery who underwent R-THA between 2005 and 2013 were identified from the United States Medicare 100% national administrative claims database. Medicare patients treated in a revision scenario with ceramic bearings exhibited similar risk of rerevision, infection, or mortality as those treated with metal-on-polyethylene bearings. Conversely, researchers found an association between the use of specific ceramic bearings in R-THA and reduced risk of readmission (C-PE) and dislocation (COC).

In this study, researchers from Drexel University quantified the volumetric material loss from the head bore and stem cone tapers of a matched cohort of ceramic and metal heads. A quantitative method was developed to estimate volumetric material loss from the head and stem taper in previously matched retrieval cohorts of 50 ceramic and 50 CoCr head-stem pairs. An order of magnitude reduction in volumetric material loss was found when a ceramic head was used instead of a CoCr head. The researchers found that ceramic femoral heads were an effective means by which to reduce metal release caused by taper fretting and corrosion at the head bore-stem cone modular interface in THAs.

Metal transfer has been observed on retrieved THA femoral heads for both CoCr and ceramic bearing materials. Researchers investigated the extent of metal transfer on the bearing surface of CoCr and ceramic femoral heads and identified prevalent morphologies. Three bearing couple cohorts were studied: M-PE (n=50), C-PE (n=35), and C-C (n=15). Surface area coverage and curved median surface area were similar among the three cohorts. The most prevalent metal transfer patterns observed were random stripes, longitudinal stripes, and random patches. Metal transfer arc length was shorter in the M-PE cohort.
