Rotator cuff injury and tears are a common source of shoulder pain, particularly among the elderly. Arthroscopic repair has now become the mainstay in the treatment of significant injuries that have failed conservative therapy. Compared with the traditional open technique, arthroscopic repair offers patients smaller incisions and less soft-tissue trauma, which result in improved postoperative pain and rehabilitation. The advances that have made arthroscopic repairs a reality includes improvement in arthroscopic rotator cuff instrumentation, particularly suture anchors. Suture anchors are used to reattach the torn rotator cuff tissue back onto the bone. Current rotator cuff anchors vary by design, anchor composition and suture materials. A treating physician should be aware of the advantages and limitations of these implants, which may influence the choice of one anchor over another. In addition to anchor variables, other factors that may affect the success of the repair include the local environment and surgical technique. In this article, various aspects of anchor design will be discussed. In addition, a concise review of technical considerations will also be discussed.
肩袖损伤和撕裂是肩部疼痛的常见原因，尤其是在老年人中。关节镜修复术现已成为治疗经保守治疗失败的严重损伤的主要方法。与传统的开放式技术相比，关节镜修复术为患者提供了更小的切口和更少的软组织损伤，从而改善了术后疼痛和康复情况。关节镜修复术成为现实的主要原因包括关节镜肩袖器械的改进，特别是缝线锚钉。缝线锚钉用于将撕裂的肩袖组织重新固定到骨头上。目前的肩袖锚钉在设计、锚钉组成和缝线材料上有所不同。治疗医生应该了解这些植入物的优点和局限性，这可能会影响对一种锚钉的选择而不是另一种。除了锚钉的变量外，可能影响修复成功的其他因素包括局部环境和手术技术。本文将讨论锚钉设计的各个方面。此外，还将简要讨论技术注意事项。
