Hip fusion takedown with total knee and hip arthroplasty in a patient with end-stage chronic kidney disease - a case report and narrative literature review.

Hip fusion takedown and conversion to [total hip replacement (THR)] is a technically demanding procedure related to a high risk of complications, however, in selected patients, it might be required before performing [total knee arthroplasty (TKA)]. Currently, there is no standard of care, and each case has to be considered individually. We describe a case of a 70-year-old male with left hip ankylosis and debilitating pain in the ipsilateral knee. We describe the justification and technical issues related to the management of this case, and the difficulties associated with performing those in a dialyzed patient. Based on our experience and available literature, we conclude that the patient has to be informed of possible complications and outcomes. Even the presence of serious comorbidity does not necessarily preclude such a procedure if the patient is in good condition and the successful outcome is highly probable.
