Comparison of patient satisfaction after unilateral or simultaneous bilateral total hip arthroplasty through a direct anterior approach: Evaluation using the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire

In this study, we observed greater improvement in JHEQ in patients treated with bilateral simultaneous THA than in those treated with unilateral THA. These findings demonstrated that bilateral simultaneous THA was related to high patient satisfaction as well as high safety.
