The use of bilobed porous-coated acetabular components without structural bone graft for type III acetabular defects in revision total hip arthroplasty
Joseph T. Moskal; Francis H. ShenHip
A prospective analysis was undertaken of 11 hips (in 11 patients) that underwent revision acetabuloplasties with bilobed, porous-coated, acetabular implants without the use of structural bone graft for type III acetabular defects. The average patient age was 66.3 years, with an average follow-up of 38 months (range, 24–49 months). No acetabular components required or are pending revision surgery. Average pain and hip scores improved from 8 and 36 preoperatively to 42 and 89 postoperatively, respectively. Average leg-length differences decreased from 34 mm preoperatively to 7 mm postoperatively. The use of bilobed acetabular components without structural bone graft is a feasible alternative for reconstructing type III acetabular defects, and can provide good short-term clinical results, while reconstructing the hip center and maximizing host-implant contact.
