Abstract
Tibial plateau fractures (TPFs) in older adults are increasing in incidence and now account for 8% of all fractures in patients over 60 years of age. Although primary fixation remains standard, the risk of fixation failure, loss of reduction, and the development of posttraumatic osteoarthritis are all markedly increased in this age group with higher rates of conversion to total knee arthroplasty (TKA) of 12%. When joint depression is severe with significant subchondral bone loss, up to half ultimately require TKA. TPFs with unicondylar depression can be managed primarily using tibial cones in acute TKA. In this study, we report the surgical technique for performing acute TKA using tibial cones for the primary management of TPFs in older adults and illustrate this technique with case examples.
