Clinical experience of ceramic cementless total knee arthroplasty in RA and a histological study of the bone-ceramic interface in revision cases.
The Kyoto total knee cementless prosthesis (KC-1) was used in 23 patients with rheumatoid arthritis. Its femoral component is made of alumina ceramics which articulated with a HDP plate supported by a ceramic plate. Although the followup period is short, the postoperative result is not satisfactory, because remarkable sinking of the tibial component was noticed in those patients who have bone atrophy. We had 6 cases of revision so far. Since 1986, we have been using bone cement in all cases of RA in doing TKA.
