Ceramic-on-Ceramic Total Hip Arthroplasty in a Twelve-Year-Old Patient: Case Report with a 27-Year Follow-Up

Total hip arthroplasty in the juvenile patient with a severely diseasedjoint can provide long-term pain relief and improvement in function. We present a patient with juvenile rheumatoid arthritis who underwent a Mittelmeier ceramic-on-ceramic total hip arthroplasty at age 12 in 1986. The implant provided the patient with a functioning hip for 24 years, but subsequently required revision due to femoral component loosening. This case report represents the longest reported clinical follow-up of noncemented, ceramic-on-ceramic total hip arthroplasty in a juvenile patient and depicts an excellent outcome at 27 years. Our case is also unique in that the Mittelmeier ceramic acetabulum was left in place during revision surgery. In this report, we also describe the senior author's choice of the Mittelmeier hip prosthesis within its historical context and provide a brief review of the literature as it relates to total hip arthroplasty in the juvenile patient.
