The results of 65 consecutive revision total knee arthroplasties performed for mechanical failure were reviewed. Fifty-nine of the knees were followed for an average of five years (range, 2-10 years). The types of implants used included: total condylar, posterior stabilized, total condylar III, and the kinematic rotating hinge prostheses. Only 46% of the knees were considered excellent or good; 42% either had poor results or failed. The infection rate was 4.5%. Poor results were generally caused by patellofemoral problems and kinematic abnormalities. Revision total knee arthroplasty is a technically demanding procedure that can improve function when anatomic relationships of the knee are restored.
