Abstract
We treated osteoarthritis of the knee (medial type) with unicompartmental knee arthroplasty (UKA), and evaluated short-term clinical results.
Five cases (five knee) were treated with UKA. The mean age was 72.0 years (1 male, 4 female), and mean follow-up period was 12 months. The mean JOA score improved from 50.0 preoperatively to 83.7 at the final follow-up period. The mean range of motion improved 123.8° to 136.2°. Partial radiolucent lines were not noted in all patients, and no components were thought to be clinically loose in the latest follow-up evaluation. UKA allows excellent short-term results with strict indications and requires careful longer term follow-up evaluation.
