[Arthrodesis following knee arthroplasty].
In 44 failed total arthroplasties of the knee joint, arthrodesis was attempted (1970-1986). The interval between implantation of the total knee arthroplasty and diagnosis of infection was more than 2 years on average. Removal of the arthroplasty and arthrodesis was performed about 1 year later. In 80% of the knees, compression arthrodesis using an AO plate was used 34 times, with solid fusion occurring after 6 months. External fixation was used in 10 patients; rate of solid fusion was only 60%. The reasons for delayed union or failure had to do with reduced bone stock in the metaphysis with poor bone quality, inadequate fixation, and uncontrolled infections.
