Total knee arthroplasty with fracture of polyethylene post

A total knee arthroplasty (TKA) is a common procedure performed in patients with symptomatic osteoarthritis that is refractory to conservative management. The use of polyethylene in prostheses has become the standard in many types of arthroplasties with improved longevity and increased patient satisfaction. We present a case of a rare postoperative complication of polyethylene post fracture detected on CT imaging in a patient who had a primary posterior stabilized total knee arthroplasty (TKA) performed several years prior.
