Aseptic loosening not a concern for patients with cementless hip implants
Cementless hip implants were not adversely affected by aseptic loosening over the long term and produced good clinical outcomes, according to study findings.
Researchers retrospectively reviewed 33 hips in 27 consecutive patients with a confirmed diagnosis of Paget’s disease who underwent primary hip arthroplasty. Patients’ mean age was 75 years. Follow-up occurred at 6 weeks and again at 1, 3, 5, 10, 15 and 20 years.
Patients were mobilized early and allowed full weight bearing in all cases except when an osteotomy was performed. The researchers evaluated modified Harris hip score (HHS), assessment of thigh or groin pain, pain grade in each area, range of motion, leg length discrepancy and limp presence.
After excluding patients who were lost to follow-up, died, or required revision, 11 patients (14 hips) were available for clinical and radiographic follow-up at the minimum 10-year mark. Mean HHS improved from 56 to 83 at final follow-up, with 73% achieving good or excellent results. No cases of dislocation or sepsis were observed.
