N2 - From 1992 to 1993, 17 elbows were replaced with the unlinked Kudo type 3 total elbow arthroplasty in 16 patients with arthritic joint destruction. Of these elbows, 8 were available for clinical examination after a mean of 9.5 years. Of the 17 elbow implants, 5 were revised: 2 because of loosening of the ulnar component, 1 because of dislocation, 1 because of a periprosthetic fracture, and 1 because of a late deep infection. At 9.5 years' follow-up, 67.9% of the prostheses had survived, and the mean survival of the implant was 8.7 years (95% confidence interval, 7.5-10 years). In this study, we observed high rates of progressive valgus tilting of the ulnar component. This valgus tilting is of major concern because it provides more stress to a smaller area on the polyethylene. It may, therefore, cause an increased degree of polyethylene wear and, thereby, reduce the final implant survival rate.
