Summary
Revision total hip arthroplasty using bulk allograft bone with the Kerboull acetabular device demonstrated successful long-term outcomes. This technique provided durable acetabular reconstruction for severe bone loss.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Bone Grafting
Background:
- Revision total hip arthroplasty (THA) is complex, particularly with significant acetabular bone loss.
- The Kerboull acetabular device, combined with bulk allograft bone, offers a potential solution for severe acetabular defects.
Observation:
- Sixty revision THAs were performed using bulk allograft bone and the Kerboull device in patients with American Academy of Orthopaedic Surgeons Type III or IV acetabular bone loss.
- The average patient age was 57.7 years, with a mean follow-up of 10 years.
- Graft consolidation was observed in all cases by 12 months, with remodeling continuing for 3-4 years.
Findings:
- A low failure rate of 5% (3 of 60 hips) due to radiologic loosening was reported at a mean 8-year follow-up.
- The 13-year survival rate, using acetabular component loosening as the endpoint, was 92.1%.
- Significant improvement in the Merle d'Aubigné hip functional score was noted, from a mean of 11.7 preoperatively to 17.4 postoperatively.
Implications:
- Acetabular allograft reconstruction supported by the Kerboull acetabular device yields satisfactory long-term clinical and radiologic results.
- This reconstructive strategy is effective for managing severe acetabular bone defects in revision THA.
- The findings support the use of allograft bone and the Kerboull device for achieving durable acetabular reconstruction.
