title: Dual Articular Knee in demanding primary and revision replacements in patients with rheumatic diseases.
abstract: We report the results of 25 total knee replacements in 24 patients with rheumatoid arthritis (RA) using the Dual Articular Knee prosthesis. There were four primary and 21 revision procedures. The main indication was severe joint instability. In four infected arthroplasties a two-stage revision procedure was used. Four patellar tendon avulsions and one deep infection were encountered. Results were excellent in 18 patients. Dual Articular Knee proved to be favourable in both demanding primary as well as revision arthroplasties in patients with RA.
