Simultaneous bilateral total knee arthroplasty as safe procedure with low risk of mortality and morbidity

BackhroundsThe aim of this study was to evaluate the morbidity, clinical outcome and mortality withsimultaneous bilateral total knee. Bilateral total knee has advantages that include bilateralfunctional recovery with only single operation and anesthesia, lower cost. But there is someconcerns about its complications and mortality rate in comparison to staged TKA.MethodsBetween 2010 and 221 ,2017 patients with bilateral end-stage osteoarhtritis hadundergone bilateral total knee arthroplasty. All cases was done by one surgeon, withsub- vastus approach.221 bilateral total knee arthroplasty were analyzed to perioperativecomplications, mortality rate and functional outcomes.ResultsThe mean Oxford knee score preoperatively was 22 which knee score postoperativelywas%90 .46.5 of patients showed excellent outcomes also %10 of patients showed defectiveoutcomes. One patient mortality occurred in our study which was 4 months after operationdue to cardiac ischemic disease. There were one periprosthetic fracture, one infection, nocomponent loosening and no other revisions. Symptomatic deep- vein, thrombosis (DVT),pulmonary embolism (PE), did not occurred in patients.ConclusionsAccording to our studies simultaneous bilateral arthroplasty is beneficial to patients, witha minimal increase in the risk of death or other complications and does not result in anysignificant increase in patient’s morbidity or compromise in postoperative function.
