Acetabular revision with extensive allograft impaction and uncemented hydroxyapatite-coated implants. Results after 9 (7-11) years follow-up.
This is a clinical and radiographic review of 87 hips in 79 patients 9 (7-11) years after acetabular revision with extensive use of morselized allograft firmly impacted into localized defects as well as the entire acetabular cavity, followed by insertion of an uncemented hydroxyapatite-coated cup with supplementary screw fixation. The 9-year survival rate for the acetabular implant was 90.5% (95% CI, 83.4%-97.6%) with revision for any reason as end point and 94% (95% CI, 89%-99.1%) with revision for aseptic loosening as end point. Acetabular revision with massive allograft impaction and hydroxyapatite-coated implants show very promising results. The limited contact between implant and host bone does not seem to compromise implant survival in the 7- to 11-year perspective.
