Metaphyseal sleeves have become an integral part of surgeons' armamentarium in dealing with complex revision knee arthroplasty. They offer the advantages of addressing bone defects with biological fixation techniques, efficient surgical preparation providing a stable tibial platform which optimises joint line positioning and gap balancing leading to excellent long-term survivorship and clinical outcomes. Here, we review the concept of metaphyseal fixation, indications of metaphyseal sleeves and their limitations with our surgical tips on how to remove well-fixed sleeves. We also present our tertiary experience and review clinical outcome studies of metaphyseal sleeves in revision knee arthroplasty literature.
干骺端套筒已成为外科医生处理复杂膝关节翻修置换术中不可或缺的工具。它们具有以下优点:采用生物固定技术处理骨缺损、高效的手术准备可提供稳定的胫骨平台,从而优化关节线定位和间隙平衡,实现出色的长期生存率和临床效果。在此,我们回顾干骺端固定的概念、干骺端套筒的适应证及其局限性,并提供关于如何取出固定良好的套筒的手术技巧。我们还介绍了我们的三级医疗经验,并回顾了膝关节翻修置换术中干骺端套筒的临床结局研究文献。
