Cementless total hip replacement in RA has rarely been reported, probably because of technical difficulties with fixation of a prosthesis due to osteoporosis and protrusion of the acetabulum. The present study concerns midterm results (follow-up of up to 3 years and 7 months, averaging 21; 1 months) for 15 cases with the cementless total hip replacement (JIAT total hip endoprosthesis) developed in Japan. The clinical results have so far been satisfactory in view of the remarkable improvement in pain and some improvement in ADL.
Examination of the tissue change around the prosthesis in a case which died 3 years, postoperatively revealed preserved trabecula a round the prosthesis and stable anchorage.
