Miller KC, Morrow BR, Sorrels JH, et al. - This research was undertaken to ascertain how different total knee arthroplasty bearing surfaces are susceptible to this type of damage and if surgeons are aware that this damage can occur. In this survey, what percentage of adult reconstructive surgeons use electrocautery after implantation of components was ascertained. Researchers selected three bearing surfaces for total knee arthroplasty: cobalt-chromium, Oxinium, and zirconium nitride to be damaged by electrocautery with monopolar and bipolar electrocautery with 3 different energy settings. Surface damage caused by electrocautery can have significant effects on the bearing surfaces of implants but future research requires to be conducted to ascertain whether this is a clinical issue. The survey ascertained that many arthroplasty experts are unaware that this damage can occur.
