BACKGROUND: Few series report the results of total elbow replacement (TER) in patients with juvenile idiopathic arthritis (JIA). Most report the use of a linked implant. There are theoretical benefits to using an unlinked prosthesis, and thus we report our experience of the clinical benefit and survivorship of both this implant and a linked semiconstrained prosthesis.
METHODS: There were 21 elbows replaced in 14 JIA patients (12 women and 2 men; 14 unlinked, 7 linked). Mean age at surgery was 39.5 years (range, 26-52 years). Mean clinical follow-up was 11.7 years (range, 5.4-17.6 years).
RESULTS: Reoperation, including implant revision, was required in 9 elbows (42.9%). Using revision as an end point, survivorship was 95% (95% confidence interval [CI], 74%-99%) at 5 years and 68% (95% CI, 45%-86%) at 10 years. The 10-year survival was 70% (95% CI, 40%-89%) for the unlinked group and 69% (95% CI, 28%-94%) for the linked group. The need for bilateral TER was found to be a risk factor for revision within 10 years of primary surgery (6/11 vs. 0/7 elbows; P = .037). The rate of aseptic loosening seen on radiographs was high in the unlinked group (12/14, 85.7%), but many of these patients continue to function well without need for revision.
CONCLUSION: Both the unlinked Kudo 5 and linked Coonrad-Morrey prostheses for TER can provide benefits in the long-term for most patients with JIA. The need for bilateral TER in this group is associated with higher rate of revision at 10 years.
