BILATERAL TOTAL HIP ARTHROPLASTY: ONE-STAGE VERSUS TWO-STAGE PROCEDURE

IntroductionDespite several studies, controversies prevailed about the rate of complications following one-stage and two-stage bilateral total hip arthroplasty (THA). In current prospective study, we compared the complications and functional outcomes of one-stage and two-stage procedures.MethodsOne hundred and eighty patients (ASA class I or II) with bilateral hip osteoarthritis were assigned randomly to two equal groups. Two groups were matched in term of age and sex. All of the surgeries were performed through the Harding approach using uncemented implants. In two-stage procedures, surgeries were performed with 6 months to one year interval. All patients were evaluated one year postoperatively.ResultsThe Harris hip score averaged 84.1±12.6 and 82.6±15.3 in one-stage and two-stage groups, respectively (p=0.528). The hospital stay was significantly longer in two-stage group (9.8±1.1 versus 4.9±0.8 days). The cumulative hemoglobin drop and number of transfused blood units were the same. One patient in each...
