CLINICAL OUTCOMEOF REVISION TOTAL ELBOW ARTHOPLASTY FOR RA ELBOWS

PurposeClinical outocome of revision total elbow arthroplasty(TEA) in rheumatoid arthritis(RA) patients were evaluated.MethodsClinical outocome of revision TEA that underwent between 2005 and 2013 were evaluated. Causes of revision, implanted revised prosthesis, a clinical score (the Japanese Orthopaedic Association (JOA) elbow assessment score), the arc of motion and complications were investigated. Totally, 6 patients underwent revision TEA. The patients were females with a mean age of 60.4 years (range, 32 to 72).ResultsSeventy-two primary TEAs were done in corresponding period. Six out of 72 (8.3%) TEAs were revised. Causes of revision were loosening, instability (dislocation) and breakage of a component in 3, 2 and 1 cases, respectively. A mean duration from initial TEA to revision surgery was 10.3 years (range, 1 to 13). Semi-constrained arthroplasties (5 Coonrad-Morrey, 1 Discovery) were used for revision surgery.A mean JOA elbow assessment score improved from 59 to 81 point at the time of follow u...
