A newly devised locking loop tendon-ligament suture was evaluated for its clinical application. The suture is relatively simple to use and is particularly suited to flat structures such as the medial collateral ligament, joint capsule, and patellar tendon. It affects tension and resistance to pull out without exerting major purse stringing or bunching. In a laboratory setting, this suture technique has been compared to fixation by individual sutures and several varieties of staple fixation. Simple suture fixation was quite weak, measuring 100 newtons (N). Staple fixation is not only weaker than the ligament suture, but is more highly dependent on bone quality and is generally more variable. When employed with strong suture material, a doubled ligament suture was found to be nearly twice as strong (392 N) as staple fixation into bone (208 N) and demonstrated a mean pullout strength close to the forces observed on human anterior cruciate ligaments. In combination with a well placed ligament staple into good quality bone, fixation was further enhanced (482 N) and statistically significantly improved (P greater than .05).
一种新设计的锁定环肌腱 - 韧带缝合线被评估其临床应用。这种缝合线使用相对简单，特别适用于内侧副韧带、关节囊和髌腱等扁平结构。它在不产生主要的抽紧或聚束的情况下影响张力和抗拔出力。在实验室环境中，这种缝合技术已与单个缝线固定和几种钉合固定方式进行了比较。简单缝线固定相当薄弱，测量值为100牛顿（N）。钉合固定不仅比韧带缝合弱，而且对骨质质量更高度依赖，并且通常变化更大。当使用强力缝合材料时，发现双股韧带缝合线的强度几乎是骨内钉合固定（208 N）的两倍（392 N），并且显示出的平均拔出强度接近在人体前交叉韧带上观察到的力。与放置良好的韧带钉合在优质骨中相结合时，固定进一步增强（482 N）且在统计学上有显著改善（P大于0.05）。
