Clinical results and complications in mobile-bearing total knee arthroplasty.

The low-contact stress mobile-bearing implant has the longest continuous follow-up, with over 25 years of data compiled in the designers' original study. In several peer-reviewed publications, the long-term outcome and clinical performance of the femorotibial articulation, patellar resurfacing, and various issues of surgical technique, such as cruciate retention or sacrifice, tibial axis alignment method of bone resection, cemented versus cementless implants, and the use of the lateral approach for patients with valgus deformed knees are analyzed. These results are compared with those of outcome studies of total knee arthroplasty in general. Results from a recent multicenter outcome study evaluate the survivorship results from surgeons around the world who have extensive experience with the low-contact stress implant.
