述评：固定方式至关重要——当技术成为生物学：半月板同种异体移植术中的固定策略
简介
这篇述评指出，半月板同种异体移植术中固定方式并非单纯技术选择，而是影响移植物生物力学与存活率的关键因素。与骨栓及骨桥技术相比，单纯缝线固定的再手术率显著更高，因其难以恢复半月板环箍应力与胫股接触力学。临床医生应优先选择能更可靠恢复半月板功能的固定策略以改善远期效果。
英文摘要
Meniscal allograft transplantation is a well-established treatment for symptomatic meniscal deficiency, yet the optimal fixation strategy remains debated. Recent studies revealed that suture-only fixation is associated with significantly higher meniscus-specific reoperation rates compared with bone plug and bone bridge-in-slot techniques. These findings reinforce that the fixation method is not merely a technical consideration, but a determinant of graft biomechanics and survivorship. Suture-only fixation may inadequately restore native hoop stress and tibiofemoral contact mechanics, contributing to increased graft extrusion, elevated joint pressures, and subsequent reoperation. Additionally, variation in outcomes by compartment and patient sex suggests that both anatomic and biological factors interact with fixation strategy. These data challenge the notion that fixation techniques are interchangeable and instead position fixation as a modifiable factor influencing clinical outcomes. Surgeons should incorporate these findings into operative decision-making and patient counseling, favoring fixation strategies that more reliably restore native meniscal function and improve long-term graft durability.
