Purpose: To retrospectively evaluate the clinical and radiology results of total knee arthroplasty using a rotating platform Low Contact Stress (LCS®) Complete™. Materials and Methods: Of 63 patients (82 knees) who had undergone a total knee arthroplasty with a rotating platform LCS® Complete™ between Jan. 2001 and Dec. 2002, 61 patients (79 knees) were followed up for more than three years and evaluated retrospectively. The average follow-up period was 3.5 years and the diagnosis in all cases was degenerative osteoarthritis. The average age at the time of surgery was 67.4 years, and no patient underwent patella resurfacing. Results: The average active range of motion increased from 118° (95°-134°) preoperatively to 123° (100°-140°) at the last follow up. The average flexion contracture improved from 15° (0°-30°) preoperatively to 2° (0°-10°) at the last follow up. The average HSS knee score also improved from preoperative 64 points to 90 points at the last follow up. The radiology evaluation revealed a radiolucency rate of 10% in the tibia anteroposterior view and 9% in the femur. The complications encountered were two cases of a polyethylene liner dislocation; one in whom an open reduction was performed, and the other in whom the liner had been exchanged. Conclusion: A follow-up of the rotating platform LCS® Complete™ of more than three years yielded overall satisfactory results in the range of motion and function. However, there should be some concern regarding the development of polyethylene liner dislocation.
