Notes:
Total hip arthroplasty (THA) in patients with sequelae of the hip joint infection is atechnically challenging procedure. In addition, the majority of such patients are less than fifty yearsold, so it has been reported that they have higher prevalence of complication and failure ofcomponent fixation. Alumina-on-alumina couplings are an attractive alternative and may offer apromising option for such young active patients. We analyzed 33 primary cementless alumina-onaluminaTHAs (PLASMACUP®SC-BiCONTACT® system incorporating BIOLOX® forte) that hadbeen performed in patients who had sequelae of the hip joint infection. The average age of thepatients was 37.8 years (range, 19-68 years) and 26 patients were younger than 50 years old. Theywere followed-up for more than 5 years (average, 74 months; range, 60-93 months). All hips had norecurrence of hip joint infection. The mean Harris hip score improved from 59.8 points to 93.5points. All of the implants had radiographic evidence of a bone ingrowth and no radiologicalloosening was found. During the follow-up period, no cup or stem was revised and no periprostheticosteolysis was observed. Nonunion of the osteotomized greater trochanter occurred in one hip, butno postoperative infection or ceramic failure was observed. The 5-year minimum follow-up clinicalresults of modern alumina-on-alumina THAs performed in patients with sequelae of the hip jointinfection were encouraging with regard to osteolysis and implant stability. Our findings show thatthis alternative articulation offers a reliable solution for these young patients with long-standinganatomic abnormalities of the bone and soft tissues
