THA improved patient-reported outcomes in patients with Legg-Calvé-Perthes disease
For patients with osteoarthritis associated with Legg-Calvé-Perthes disease, total hip arthroplasty provided excellent improvements in patient-reported outcomes and an acceptable complication rate, according to published results.
Researchers performed a retrospective, single-center review of data on 61 patients (average age of 42 years) who underwent THA for residual Legg-Calvé-Perthes disease (LCPD) deformities. Among the cohort, 26% of patients had previous hip surgery.
According to the study, researchers used a validated grading scheme based on required treatment and persistent disability to categorize complications. Additionally, patient-reported outcomes (PROs) were compared preoperatively to final postoperative follow-up.
Overall, PROs improved preoperatively to postoperatively in all patients with the modified Harris Hip Score improving from 46.9 to 85.4, respectively. Three patients (5%) experienced major complications, which required second surgical intervention, seven patients experienced minor complications – most commonly asymptomatic heterotopic ossification – and one patient required a revision of the femoral component.
“Previous reports have found treating residual LCPD with THA can be associated with a higher complication profile, inferior PROs and an increased revision rate when compared with patients undergoing THA for osteoarthritis,” the researchers wrote in the study. “In a relatively large series of patients, we find an acceptable complication rate, with the majority of complications consisting of either medically treated problems or clinically unimportant heterotopic ossification,” they concluded.
