Information was received based on review of a journal article titled, "tribocorrosion: ceramic and oxidized zirconium vs cobalt-chromium heads in total hip arthroplasty," which aimed to compare tribocorrosion between matched ceramic and cobalt-chromium femoral head trunnions, and between matched oxinium and cobalt-chromium #cocr# femoral head trunnions.Secondary objectives were to investigate if taper design, depth of trunnion, implantation time, age, body mass index and gender have an effect in fretting and corrosion.The study consisted of 1320 implants evaluated to ensure an exact match for taper design and head size, and best possible match for neck length and implantation.All prostheses were retrieved between 1999 and 2015.A patient was identified in the article that underwent a total hip arthroplasty on an unknown date.Patient follow-up results provided at 10.3 years post-implantation indicates patient underwent a revision procedure due to polyethylene wear.There has been no further information provided and the patient outcome is unknown.
