Revascularization of a total bulk acetabular allograft at 14 years

This case report describes the long-term outcome of a total bulk acetabular allograft placed for bone substitution after resection of recurrent pigmented villonodular synovitis of the hip joint. After 14 years in situ, the graft had completely incorporated and showed viable bleeding bone surfaces in all areas of the acetabular implant interface. The possibility of a bulk corticocancellous allograft to undergo revascularization over a long period of time has not been previously documented.
