Abstract

We report the surgical technique used to perform posterior-stabilized total knee arthroplasty (TKA) in two patients with a well positioned and functional hip arthrodesis. Intraoperatively, the operating table was placed in an increased Trendelenburg position. Episodically, we flexed the foot of the table by 90° to allow maximal knee flexion to facilitate exposure and bone cuts. We opted to resect the patella and tibia first to enable exposure, given the stiffness of the arthritic knee. One patient’s medical condition prohibited complex conversion total hip arthroplasty (THA) prior to the TKA. The other patient’s scarred soft tissues around the hip, due to chronic infection and multiple operations, made THA risky. The final outcome provided satisfactory results at a minimum of 2 years postoperatively. TKA can be successfully performed with adjustments of table position and modification of the sequence of surgical steps in patients with ipsilateral hip fusion.
