The KT plate is a metal supporter for a deficient acetabulum, designed by C. Tanaka. Between April 1999 and March 2000, we performed total hip arthroplasty with KT plates and morcellized bone graft for seven patients (eight hips) with severe bone loss in the acetabulum. The preoperative diagnoses were rheumatoid arthritis in four hips (three patients), osteoarthritis in three hips (three patients) including two revision surgeries, and rapidly destructive coxarthropathy in one hip. All seven patients were women, and the average age at surgery was 68.4 years old (range, 52-82 years) . Patients were followed for 7 to 18 months (mean, 12.3 months) . All patients, except the two who received revision surgery, started weight bearing at 3 to 7 weeks after operation. In spite of the early weight bearing, no collapse of the grafted bone or loosening of the KT plate was observed, and the clinical courses of the patients were encouraging.
