Abstract

A series of 66 primary Optetrak Posterior Stabilized total knees with modular tibial components were followed prospectively for a minimum of 5 years in patients with osteoarthritis. Fifty-one percent of the patients were obese based on body mass index greater than 30. There was a statistically significant negative correlation between body mass index and both Hospital for Special Surgery and Knee Society scores. Despite reduced ratings due to obesity, 90% of the patients were rated good or excellent. Patellofemoral design changes nearly eliminated patellofemoral crepitation and soft tissue entrapment. Design changes did not compromise implant survival. Predicted implant survival at 93 months using reoperation for any reason as an end point was 97%.
