Limberg AK, et al. - This study was intended to evaluate mid-term survivorship, complications, and clinical outcomes of a fixed-bearing varus-valgus constrained (VVC) device in revision  total knee arthroplastis (TKAs). Researchers included a sum of 398 individuals to perform 416 consecutive revision TKAs at the institution applying a single fixed-bearing VVC TKA Between 2007 and 2015. Via competing risk analysis, survivorship was analyzed; Knee Society Scores and range of movement (ROM) were applied to ascertain clinical outcomes. In this study, mean follow-up was four years (2 to 10). At five years, with this fixed-bearing VVC implant in revision TKAs, the cumulative incidence of subsequent revision for aseptic loosening and instability was found to be very low. This study's findings indicate that routine use of cemented and stemmed components with targeted use of metaphyseal cones likely contributed to this low rate of aseptic loosening.
