The anterior cruciate ligament (ACL) is the most frequently injured knee ligament that requires surgical intervention. Surgical options to address ACL ruptures include reconstruction using autograft or allograft or performing primary repair. Subsequent ACL graft failure is a significant postoperative concern in the younger patient population. The addition of suture tape to the final construct is thought to protect the graft during moments of high stress by increasing graft stiffness under high load and preventing substantial graft elongation. Given the normal anatomic lengthening of the ACL from knee flexion to full extension, final fixation of both the suture tape and the graft is done with the knee hyperextended to avoid overconstraint. The use of adjustable loop fixation for both femoral and tibial fixation with the all-inside technique allows the graft to be retensioned after final suture tape fixation and subsequent knee cycling. This ensures that the suture tape is slightly laxer than the graft so that the graft experiences loads that are essential for its healing, with the suture tape sharing the load only during times of high stress.
前交叉韧带(ACL)是最常受伤且需要手术干预的膝关节韧带。治疗ACL断裂的手术选择包括使用自体移植物或异体移植物进行重建或进行一期修复。在年轻患者群体中,ACL移植物随后的失败是一个重大的术后问题。在最终结构中添加缝合带被认为可通过在高负荷下增加移植物刚度并防止移植物大幅伸长,从而在高应力时刻保护移植物。考虑到ACL从膝关节屈曲到完全伸展的正常解剖学延长,缝合带和移植物的最终固定均在膝关节过伸时进行,以避免过度约束。采用全内置技术对股骨和胫骨固定均使用可调环固定,可在最终缝合带固定及随后的膝关节屈伸运动后对移植物进行重新张紧。这确保缝合带比移植物略松弛,以便移植物承受对其愈合至关重要的负荷,而缝合带仅在高应力时刻分担负荷。
