全内全软组织无锚钉半月板同种异体移植术
简介
该文介绍了一种全关节内、全软组织、无锚钉的半月板同种异体移植技术。通过标准入路制备胫骨骨道，采用手打结缝线将移植物从后向前固定于半月板-关节囊交界处，无需使用锚钉。该技术可精确调整移植物匹配度，避免锚钉相关并发症，且可同期行韧带重建或胫骨高位截骨术，是一种可重复、低成本的微创替代方案。
英文摘要
Meniscal allograft transplantation is an effective surgical option for patients with irreparable meniscal pathology, including chronic root tears, complex or radial tears, and prior meniscectomy. This Technical Note describes an all-inside, all-soft-tissue, anchor-free arthroscopic technique for meniscal allograft transplantation designed to maintain a truly minimally invasive approach. Standard anteromedial, anterolateral, and mid-medial collateral ligament portals are used to prepare the meniscocapsular junction and create tibial tunnels for the anterior and posterior roots. The meniscal allograft is sequentially implanted from posterior to anterior, with meniscus-to-meniscus hand-tied sutures providing secure fixation without the use of anchors. The technique allows precise graft adjustment to accommodate minor size mismatch and minimizes risks associated with anchor displacement or failure. Concomitant procedures such as ligament reconstruction or high tibial osteotomy can be performed simultaneously. This anchor-free, all-soft-tissue technique offers a reproducible, cost-effective alternative to conventional fixation methods while preserving minimal invasiveness and ensuring strong graft integration by continuous fixation of the allograft to the native meniscocapsular junction, anatomic restoration of both meniscal roots, and robust hand-tied suture fixation that provides controlled tensioning and uniform graft compression without reliance on anchors.
