Geary MB, Macknet D, Ransone M, et al. - This research was sought to distinguish the rates and mechanisms of failure of revision total knee arthroplasty (TKA), and compare those between a historic (1986-2005) and modern (2006-2015) cohort. Researchers examined all revision TKAs conducted at a single institution between 1986 and 2015, with minimum 2 year follow up. They characterized failure as a second revision surgery in which any component was exchanged. They ascertained diagnosis at the time of index and any re-revision procedure. This study included 1,632 revision TKAs including a total of 1,560 patients. It was reported that in revision TKA, there remains a high rate of failure, with infection being the most common reason for failure. The data showed that the rates and primary reasons for failure have not changed significantly in the past decade.
