Cementless total knee arthroplasty (TKA) offers a number of conceptual benefits including osteointegration, bone preservation and reduced aseptic loosening from third body wear. Evidence of equivalence to cemented fixation exists, but the cam-post interaction of posterior-stabilised (PS)-TKA on implant osteointegration remains uncertain. This study aims to assess the survivorship of a single prosthesis PS-TKA. All patients undergoing a PS-TKA using the Triathlon Total Knee System (Stryker Orthopaedics, USA) between 01/01/2010 and 08/04/2019, with exposure to at least 2 years’ risk of revision were identified from the hospital database.Abstract
