Abstract

There is a renewed interest in cementless total knee arthroplasty (TKA) due to improved biomaterials, desire for decreased surgical times and the potential increased longevity. Seventy-three cementless TKAs (AGC, Biomet, Warsaw, Ind) were performed from 1984 to 1986. All components were implanted without cement and without screws and obtained minimum 10 years of follow-up. No patient was lost to follow-up. Fifteen failures occurred, including 12 failed metal-backed patellae, and survivorship for aseptic loosening of any component was 76.4% at 20 years. Two tibial components failed of aseptic loosening at 1.1 and 2.2 years. Excluding patella failures, the survivorship for the cementless tibial component was 96.8% at 20 years. There were no femoral component failures. After eliminating patella failures, this cementless monoblock tibial component without screws demonstrated excellent 20-year survivorship.
