Abstract

A popular rotating-platform total knee implanted with a cementless technique was studied to determine long-term durability of fixation. A total of 70 knees in 59 patients (34 men, 25 women) was included. The primary indication for surgery was osteoarthritis (80%). A total of 23 of the 70 knees was available at final follow-up (average, 16 years). Clinical and radiographic data suggested durable fixation. In addition, the entire cohort of patients was studied with Kaplan-Meier statistics. Survivorship with respect to aseptic loosening was 97% at 17 years. Only 1 of the 70 knees was revised for aseptic loosening. However, overall survivorship was 76%, which was primarily because of failures of the metal-backed rotating patella.
