Introduction. The number of patients undergoing a Primary Total Knee Arthroplasty (PTKA) has been increasing steadily each year. Of those PTKA patients, 20% report long-term pain and/or some functional deficit. Cobalt-Chromium-Molybdenum (CoCrMo) alloy is one of the most used materials in Total Joint Arthroplasty (TJA) implants due the material’s high strength, high corrosion resistance, and biocompatibility. The release of metal ions and potential occurrence of metallosis in TJA has been shown to be detrimental to the longevity of the implant. The mechanisms leading to this increase in metal ion concentrations have been up for debate, with some believing it is …
