BAC KGROUND: Total hip arthroplasty (THA) is a rare procedure in pediatric patients. Although it shows excellent results in adults, the presence of growth plates, the limited longevity of implants, and the hip-spine biomechanics involved during growth make the outcomes of THA in children uncertain.
OBJECTIVE: We hypothesized that THA yields satisfactory results for children suffering from unmanageable pain due to hip joint osteoarthrosis.
METHODS AND SETTINGS: 27 patients aged <18 years who underwent THA for hip joint osteoarthritis at our hospital between 2015 and 2022 were retrospectively included. Primary outcomes included two clinical scales: the Postel Merle d'Aubigné (PMA) and Oxford scale. Secondary outcomes included chronic pain relief and complications.
RESULTS: Mean age at surgery was 13.7± 1.7 years (min11, max 17). The mean follow-up was 5.4±2.4 years (min 3, max 10). Etiology of osteoarthrosis was slipped capital femoral epiphysis (n=13), idiopathic hip chondrolysis (n=4), femoral neck fracture (n=3), developmental hip dysplasia (n=3), hip joint infection (n=2), aseptic osteonecrosis secondary to drepanocytosis (n=1), and Legg-Calvé-Perthes disease (n=1). The average Oxford score was 43.2±4.8, and the mean PMA score was 15.9±0.6. Pain relief was achieved in 96.3% of patients. Six patients had major complications (22.2%), with three (11.1%) requiring unplanned surgeries.
LIMITATIONS: The main limitations were a small sample size and the absence of a control group.
CONCLUSION: To date, no study has specifically evaluated THA clinical outcomes in children with non-inflammatory hip joint osteoarthritis. This study demonstrates satisfactory outcomes following THA in children with hip joint osteoarthritis. THA should be considered a viable option for selected pediatric patients.
