Uncemented rotating-platform total knee replacement: a five to twelve-year follow-up study.

Background: Mobile-bearing knee designs represent an alternative to conventional fixed-bearing total knee arthroplasty. We present the results of a prospective, intermediate-term clinical follow-up study of the bicruciate ligament-sacrificing porous-coated Low Contact Stress rotating-platform total knee design.

Methods: Between February 1984 and January 1994, 528 uncemented primary knee replacements were performed in 421 patients.
