关节镜下使用纤维蛋白凝块增强联合“井号”式由内向外技术修复半月板放射状撕裂
简介
该文介绍了一种关节镜下结合纤维蛋白凝块增强与“Hashtag”式由内向外缝合技术修复内侧半月板体部放射状撕裂的手术技巧。通过采集30毫升自体血制备纤维蛋白凝块，经气管导管置入撕裂处，并以“ripstop”构型缝合固定，旨在提高血供较差区域的愈合率。术后需4周非负重、8周逐步恢复完全负重，该技术成本低、操作简便，适用于需要生物增强的高风险半月板撕裂修复。
英文摘要
Significant meniscal injuries lead to pain and possible early osteoarthritis development. Fibrin clot augmentation represents an effective, cost-efficient method for improving healing rates in poorly vascularized meniscal tears. This arthroscopic technique shows fibrin clot augmentation combined with horizontal and vertical mattress sutures in a "ripstop" configuration for radial midbody medial meniscus tears. Thirty milliliters of autologous blood is collected and processed to form a fibrin clot, which is introduced inside-out through an endotracheal tube to optimize surface contact within the tear. The clot is secured with braided sutures while meniscal repair is performed using 2-0 polydioxanone sutures in a ripstop configuration. A similar technique may be used for any repair requiring biological augmentation. Rehabilitation protocols include 4 weeks of nonweight-bearing, followed by graduated weight-bearing to achieve full weight-bearing by 8 weeks. Range-of-motion restrictions vary by tear location. This technique provides a cost-effective, low-complexity technique for biological augmentation of repair of high-risk meniscus tears, potentially improving healing probability.
