Abstract
We reviewed 42 hips which had undergone revision THA between 1995 and 2005 (the Kerboull plate in 24 hips, and the KT plate in 18 hips). Patients were followed-up for a mean of 7.5 years (range 3-13). In the Kerboull plate group, the five- and ten-year survival rates were 89.9% and 79.4%, respectively. In the KT plate group, the five-year survival rate was 87.5%. The Kerboull and KT plates are placed as close as possible to the original acetabular position and used in combination with a bone graft for bone defects. In Japan, for patients with large bone defects, femoral heads with good quality which have been resected due to osteoarthritis are difficult to prepare as bone grafts. Therefore, use of the KT plate can reduce the bone graft volume to a certain extent by high placement, which was effective in our cases.
