From 1990 to 1998, 11 Miller-Galante Unicompartmental Knee Arthroplasties were evaluated clinically and radiographically on cases followed up for more than one year. The mean age was 71.6 years, and mean follow-up period was 2.9 years. All patients had underwent medial compartmental replacements, with 7 osteoarthritis and 4 osteonecrosis. The mean JOA score improved from 56.8 preoperatively to 87.3 at the final follow-up period. The mean range of motion improved from 125.1° to 127.5°. Partial radiolucent lines were noted in about 7 femoral components and 5 tibial components. No components were thought to be clinically loose in the latest follow-up evaluation. Unicompartmental knee arthroplasty allows good-excellent early results with appropriate patient selection and requires careful longer term follow-up evaluation.
