Forty eight cementless Miller-Galante total knee arthroplasties in 35 patients were evaluated rentogenographically. Twelve patients (15 knees) had rheumatoid arthritis and 12 patients (35 knees) had osteoarthritis. Mean age was 66.9 years, ranging from 53 to 80 years. Mean follow up period was 28.8 months with a range from 12 to 60 months. Good position of femoral and tibial components and good alignment of femoro-tibial angle was obtained in all joints, but incongruency of patello-femoral joint increased with time. Gap which was seen one month postoperatively disappeared one year later. Femoral subsidence was seen anteriorly and tibial subsidence was seen postero-laterally but these changes had not increased one year postoperatively. No patellar subsidence was seen in any joints. No radiolucency occurred around the pegs of any components. Tibial radiolucency was seen antero-medially and patellar radiolucency was seen at the edge. Femoral radiolucency was not seen in the majority of cases. These radiolucencies were less than 1mm and the width of radiolucency did not increase after one year postoperatively. These data were considered to be satisfactory except for the patero-femoral joint.
