由于接触力学的变化，半月板的完全切除（半月板切除术）通常会导致骨关节炎早发1,2。为了抵消这些变化，移除的半月板通常用同种异体移植物代替。许多变量会影响半月板移植的手术结果（骨几何形状、移植物尺寸、固定技术、活动水平、肢体对齐等）3,4,5。其中，固定方法是最容易控制的。两种常用的技术是：（i）通过骨塞进行经骨缝合固定，其中骨塞在移植物的前角和后角处加工并植入适当尺寸的胫骨骨隧道中，以及（ii）半月板角处的缝合固定，其中缝合线穿过胫骨骨隧道并绑在骨桥上。但这些固定技术的机械后果，特别是它们如何影响膝盖力学尚不清楚。版权所有 © 2013 ASME
Complete removal of the meniscus (meniscectomy) often leads to early-onset of osteoarthritis due to changes in contact mechanics1,2. To counteract these changes, the removed meniscus is often replaced with an allograft. Many variables can affect the surgical outcome of meniscal transplantation (bone geometry, graft size, fixation technique, level of activity, limb alignment, etc.)3,4,5. Among them, the method of fixation is the most readily controlled. Two commonly used techniques are: (i) trans-osseous suture fixation via bone plugs, where bone plugs are machined at the anterior and posterior horns of the graft and implanted into appropriately sized tibial bone tunnels, and (ii) suture fixation at the meniscal horns, where the sutures are drawn through tibial bone tunnels and tied over a bone-bridge. But the mechanical consequences of these fixation techniques, specifically, how they affect knee mechanics are unclear.Copyright © 2013 by ASME
