Ten to fourteen year survival and functional analysis of the AGC total knee replacement system

A study of 562 Anatomic Graduated Component (AGC) total knee arthroplasties that were performed in 402 patients between November 1986 and September 1990 is reported. All patients had implantation with a cemented posterior cruciate-retaining design, with resurfacing of the patella using all polyethylene patella components. Mean age at surgery was 71 years (range 4192 years). Patients were followed for a minimum of 10 years (range 10-14 years). Nine knees were lost to follow-up (1.4%). The mean Knee Society Score for pain and function were analyzed by Charnley categories: Category A - 97 (pain) and 89 (function); Category B - 91 (pain) and 84 (function); and Category C - 89 (pain) and 62 (function). The survival analysis at 14 years was 97% with revision for any reason as the endpoint and the authors continue to utilize this implant system. (C) 2002 Elsevier Science B.V. All rights reserved.
