The anterior cruciate ligament (ACL) is a primary restraint to anteroposterior as well as rotatory knee laxity. In case of concomitant lesion of menisci or other ligamentous structures, further dynamic instability is encountered. A lateral extra-articular tenodesis (LET) augmentation has been proposed by the Authors to treat or prevent residual laxity.
ACL reconstruction is recommended in young athletes involved in pivoting sports, non-contact pivoting injuries, high-grade pivot shift, deep notch sign and double bone bruise, meniscal loss, and revision of previous bone-patellar tendon-bone autograft.
A 2 to 3 cm oblique incision is made over the pes anserinus. Gracilis and semitendinosus tendons are harvested with their attachment preserved and sutured together. Tibial tunnel is reamed after positioning of a guide pin. A wire-loop passer is directed from the tibial tunnel to the anteromedial portal. A 2 to 3 cm longitudinal incision is made superior-laterally, the ileotibial band is divided and retracted anteriorly. A suture-loop is retrieved from the lateral incision through the anteromedial portal with a curved Kelly clamp. The suture is placed into the wire-loop and retrieved with it from the tibial tunnel. The graft is retrieved from the lateral incision, tensioned with the knee at 70° to 90° of flexion and foot in neutral rotation and secured with 2 staples to the femur. A 1-cm skin incision is performed just below the Gerdy tubercle. The graft is retrieved from this incision below the fascia with a small Kelly clamp, tensioned and secured with a staple. The iliotibial tract defect is closed.
At long-term follow-up, a revision rate of 3% has been reported, while patient-reported outcome measures (PROMs) were excellent. At very-long-term follow-up, most patients were still involved in sports with a very low rate of positive Lachman and pivot shift tests. No overconstraint and lateral osteoarthritis were encountered. Medial osteoarthritis was related only to medial meniscectomy.
DISCUSSION/CONCLUSION: The ACL reconstruction plus LET over-the-top technique is a safe and reliable surgery with a low rate of reoperations and peri-operative complications at very-long-term follow-up.

前交叉韧带(ACL)是限制膝关节前后及旋转松弛的主要结构。若同时存在半月板或其他韧带结构损伤,会出现进一步的动态不稳定。作者提出采用外侧关节外肌腱固定术(LET)加强治疗或预防残余松弛。
对于从事旋转运动的年轻运动员、非接触性旋转损伤、高级别轴移试验阳性、深沟征和双骨挫伤、半月板损伤以及既往骨-髌腱-骨自体移植翻修的患者,建议进行ACL重建。
在鹅足处做一个2至3厘米的斜切口。保留股薄肌和半腱肌肌腱的附着点并将其切取下来后缝合在一起。在定位导针后扩钻胫骨隧道。使用钢丝环推送器从胫骨隧道穿至前内侧入口。在膝关节外上侧做一个2至3厘米的纵向切口,切断髂胫束并向前牵拉。用弯血管钳经前内侧入口从外侧切口取出缝线环。将缝线放入钢丝环并随其从胫骨隧道取出。从外侧切口取出移植物,在膝关节屈曲70°至90°且足部中立旋转位时对移植物进行张力调节,并用2枚吻合钉固定于股骨。在Gerdy结节下方做一个1厘米的皮肤切口。用小血管钳经此切口在筋膜下取出移植物,进行张力调节并用吻合钉固定。关闭髂胫束缺损处。
长期随访报告的翻修率为3%,而患者报告的结局指标(PROMs)良好。极长期随访时,大多数患者仍可参与运动,Lachman试验和轴移试验阳性率很低。未出现过度约束和外侧骨关节炎。内侧骨关节炎仅与内侧半月板切除术有关。
讨论/结论:ACL重建加LET过顶技术是一种安全可靠的手术,在极长期随访中再次手术率和围手术期并发症发生率较低。
