Complications and Revision Rate as the Type of Prosthesis of Total Elbow Replacement: Long-term Follow-up in Korea

Abstract

Purpose: Few studies have compared the outcomes, complications and revision rate of a total elbow replacement (TER) prosthetic design. This study examined a series of patients with semiconstrained and unconstrained total elbow replacements (TER) and evaluated them for any functional differences, complications and revision rates that might be attributable to the prosthetic design. Materials and Methods: A total 78 cases of primary TER was performed in 71 patients. Their mean age at TER was 54 years. The causes of TER were rheumatoid arthritis in 42, post-traumatic arthritis and osteoarthritis 24 and 5 patients, respectively. Unconstrained and semiconstrained TER was employed in 35 and 43 cases, respectively. The end results of TER by the Mayo elbow performance score (MEPS), their elbow range of motion before and after surgery, their complications and revision rates after an average 13 year follow-up were evaluated. Results: The MEPS was improved from 33 points pre-operatively to 87 points post-operatively (p pre-operatively to postoperatively (p
