Revision total hip arthroplasty using a Kerboull-type acetabular reinforcement device and allogeneic structural bone graft.

A KT plate with an allogeneic structural bone graft is a useful method of acetabular reconstruction in revision THA that restores bone stock and improves hip function. Our findings indicated that a Kawanabe classification of stage 4 was a risk factor for radiological failure of the implant.
