Total elbow arthroplasty is the most established definitive surgical treatment for severe rheumatoid arthritis. This patient has pain and loss of function with radiographs that show degenerative changes consistent with rheumatoid arthritis. This would be classified as a Larson grade C with bony architectural changes on its way to joint destruction (Grade D). This is the original indication for total elbow arthroplasty.
The Kokkalis article is a current concepts review which covers other indications and results.
The Skytta paper is from the Finnish joint registry and looks at the survival rates of different total elbow implant designs. Linked implants have shown improved survival.
