Total hip revision in patients with isolated aseptic loosening of the acetabular component

Introduction Aseptic loosening of the acetabular component is one of the most common late complications of total hip arthroplasty. Current principles of its treatment consist in replacement of the loosened cup and of the head-and-liner friction couple. There is no unified opinion regarding the stem if it is stable and well-aligned. Methods We have analyzed examination and treatment results of 16 patients with isolated aseptic loosening of the acetabular component that underwent total revision. The results of treatment were assessed using the Harris Hip Score and Oxford Hip Score questionnaires on the 10th postoperative day, and then at follow-ups after three, six and 12 months. Results The average duration of the operation was 132.5 [115; 150] minutes. Intraoperative blood loss ranged from 600 to 2500 ml and averaged 900 ml [750; 1450]. Analysis of hematological parameters (RBC, HGB, HCT) showed moderate anemia in 14 patients (87.5 %) and only two patients (12.5 %) had mild anemia on the 10th postoperative day...
