Dissociação traumática do inserto tibial com ruptura do tendão patelar após artroplastia total do joelho com a prótese Genesis II de alta flexibilidade e estabilização posterior

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.
