Traumatic dissociation of the tibial insert with patellar tendon rupture after high-flex posterior-stabilized Genesis II total knee arthroplasty

Abstract

ABSTRACT The authors report the first case of traumatic late dissociation of the polyethylene insert with patellar tendon rupture after total knee arthroplasty using a high-flex posterior-stabilized Genesis II prosthesis in a 60-year-old Parkinson's disease patient. Insert dislodgement has been described most commonly with mobile-bearing and cruciate-retaining TKAs. Only four cases of insert dissociation in a high-flex fixed-bearing prosthesis have been described to date. This case report paves the way to understanding the potential reasons for insert dissociation and its management strategy.
