The Evaluation of Ligament Function in Whiteside Total Knee Arthroplasty

Abstract

The purpose of this study was to evaluate ligament function in Whiteside total knee arthroplasty, using a Telos stress devise. Forty-seven knees in thirty-seven patients were observed for a minimum of 5 years. Ten knees (42%) with rheumatoid arthritis, and 2 knees (12%) with osteoarthrosis, showed posterior instability. There was a significant difference in insufficiency rates of PCL between arthritis mutilans and other types of rheumatoid arthritis (p = 0.03) . This study indicates that patients with arthritis mutilans should undergo posterior-stabilized type TKA.
