Abstract
Patients with Legg-Calvé-Perthes Syndrome (LCPS) are at an increased risk for developing osteoarthritis of the hip and undergoing total hip arthroplasty (THA) at an early age. Importantly, this younger age may put them at a higher risk for failure and revision surgery. The purpose of the study was to assess the clinical and radiographic outcomes as well as implant failure rate and risk for revision surgery at an average 20 years follow up.
Data from LCPS patients treated with THA were collected including age, gender, operative date, revision date, as well as reason for and type of revision. Living patients filled the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaires at the time of last follow-up. Radiographs were evaluated for lucencies, debonding, loosening, osteolysis, wear, heterotopic ossification and sclerosis.
Nineteen patients (20 hips) treated with THA were followed-up for a mean of 18.3 years (range, 10.1 - 36.2 years). Radiographic evidence of lucency of the acetabular component was seen in 70% of the patients and femoral cortical hypertrophy in 85% at last follow-up. The rate of revision for any reason was 35%, mostly due to aseptic acetabular loosening.
Our findings support the use of THA for the treatment of OA in patients with LCPS, bearing in mind the potentially lower survival rate at 20 years as compared those treated with THA for primary OA. Further studies are needed to identify the possible causes of the high rate of cortical hypertrophy seen in this patient population.Level of Evidence: IV Therapeutic.
