Knee dislocation after total knee arthroplasty, although rare, is a dangerous injury that can lead to neurovascular compromise and permanent disability. With the increase in number of total knee arthroplasty, more and more cases of dislocations are being reported. We describe a novel technique of reshaping the post of a constrained liner to fit into the box of a vanguard primary knee system in a patient with recurrent posterior knee dislocation after a PS TKA with a follow-up of 5 years.
