Patient-reported Outcomes and Perioperative Complications of Total Hip Arthroplasty following Joint Preservation Surgery for Hip Dysplasia

Abstract Background There is growing recognition of the importance of patient-reported outcome measures and assessment of patient satisfaction in the evaluation of outcomes following surgical interventions. This study aimed to evaluate patient-reported outcomes and complication rates after total hip arthroplasty following joint preservation surgery for hip dysplasia. Methods Patient-reported outcomes and complication rates of 85 hips with previous joint preservation surgery (salvage group) were compared with those of 1,279 hips without joint preservation surgery (primary arthroplasty group). As a patient-reported outcome measure, the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire was used to evaluate the hip condition both preoperatively and 12 months postoperatively. Operative data and postoperative (within 12 months) complications were investigated. Results The salvage group had a longer operative time (56.8 min vs. 44.9 min, P Conclusion This study demonstrated a lower rate of improvement in patient satisfaction and worse self-reported outcomes in the salvage group. Furthermore, these patients had a longer operative time and a higher risk of operative complications.
