A Comparative Study Between Uncemented and Hybrid Total Hip Arthroplasty in Octogenarians

The aim of this prospective cohort study is to evaluate the outcome of octogenarian patients undergoing uncemented total hip arthroplasty (THA) with a control group of similarly aged patients undergoing hybrid THA with a minimum 5-year follow-up.

Clinical outcomes including intraoperative and postoperative complications, blood transfusion, revision rate, and mortality were recorded. Radiological analysis of preoperative and postoperative radiographs assessed bone quality, implant fixation, and any subsequent loosening.

One hundred forty-three patients (mean age 86.2 years) were enrolled in the study. Seventy-six patients underwent uncemented THA and 67 underwent hybrid THA. The uncemented cohort had a significantly lower intraoperative complication rate (P = .017) and also a lower transfusion rate (P = .002). Mean hospital stay (P = .27) was comparable between the 2 groups. Two patients underwent revision surgery in each cohort.

Our study demonstrates that uncemented THA is safe for the octogenarian patient and we recommend that age should not be a barrier to the choice of implant. However, intraoperative assessment of bone quality should guide surgeons to the optimum decision regarding uncemented and hybrid implants.
