Background: Little information is available regarding mid- and long-term outcomes with the JACE unlinked elbow prosthesis.
Design: We evaluated the J-alumina ceramic elbow (JACE) total elbow arthroplasty (TEA) in 17 patients with rheumatoid arthritis (RA) to provide additional information regarding this prosthesis.
Methods: JACE TEA was performed on 25 elbows in 17 patients with RA, among whom one was revised and one was lost to follow-up. Accordingly, 22 elbows in 15 patients were radiologically and clinically reviewed during a mean follow-up of 83.5 months. Outcomes were evaluated by changes in the range of motion and Japanese Orthopedic Association (JOA) functional evaluation scores for the elbow joint.
Results: Both the range of motion and JOA functional evaluation scores for the elbow joint were significantly improved by the final examination. Intraoperative fractures occurred in two patients (8%) elbows. Aseptic loosening, prosthesis dislocation, deep infection, and ulnar nerve palsy were not identified in any cases.
Conclusion: In cases with adequate bone stock in the humeral condyles and retained ligamentous integrity, JACE TEA can yield satisfactory functional results using cement, which appears to be crucial for JACE prosthesis implantation.
