As a result of better patient selection, implant design, and surgical technique, the long-term results of total elbow arthroplasty in patients with rheumatoid arthritis has improved significantly over the past 10 years. The semiconstrained hinge implant is used in the presence of severe bone and ligament destruction. The non-constrained surface replacement requires intact bone and ligamentous supports. Best results are obtained if surgery is undertaken before severe soft tissue contractures, muscle atrophy, and neurologic disability of the involved extremity develop.
由于更好的患者选择、植入物设计和手术技术，在过去10年中，类风湿性关节炎患者全肘关节置换术的长期效果有了显著改善。半限制型铰链式植入物用于存在严重骨骼和韧带破坏的情况。非限制型表面置换需要完整的骨骼和韧带支撑。如果在受累肢体出现严重软组织挛缩、肌肉萎缩和神经功能障碍之前进行手术，则可获得最佳效果。
