Abstract
The joint capsule of the knee joint is attached to the edges of various articular surfaces and is thin and loose. Therefore, ligament reinforcement is needed to protect the knee joint and increase the stability of the joint. It plays a vital role in human activities. In this paper, a 3D-CT three-dimensional reconstruction method is used to reconstruct the ACL natural femoral imprint and double-bone tract. The relative positional relationship between the two center points is compared, and the law is summarized to guide the improvement of ACL anatomic double-beam reconstruction under arthroscopy. The 3D reconstruction results suggest that the bone layer in the anterior medial portion is the thickest, forming a peak, and the thickness of the bone layer in the posterior medial portion gradually decreases in a stepwise manner. The entire bone tissue in the anterior medial portion and posterior medial portion is integrated into one body. The tissues are connected as a whole, and the thickness is relatively uniform. The two parts of the bone tissues are not connected. The CF tissue was inserted into the bone tissue in a zigzag pattern. The changes of CF tissues in the anterior medial and posteromedial CF tissues were similar, and they were distributed stepwise from the inside to the outside. According to the bone and CF spatial structure and changing rules, ACL is divided into medial and lateral beams. According to this study, it can be summarized that (1) 3D reconstruction can clearly reconstruct the natural footprint of ACL femoral stops and postoperative osseous position and (2) 3D reconstruction can be used to evaluate the position of osseous postoperative ACL anatomic double-beam reconstruction. Arthroscopy double-beam reconstruction of ACL is instructive.
Highlights
With the increasing popularity of mass movements and the increasing incidence of traffic accidents, anterior cruciate ligament (ACL) injury is becoming more and more common, and research on it has received more and more attention from the academic community [1,2,3]
Band-shaped tissues connected between the femur and tibia. e knee ligaments mainly include anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL). e anterior cruciate ligament is the most important stabilizing factor. e anterior cruciate ligament starts from the anterior angle of the meniscus and anterior to the tibial intercondylar eminence, and ends behind the medial side of the femoral condyle

Summary
With the increasing popularity of mass movements and the increasing incidence of traffic accidents, anterior cruciate ligament (ACL) injury is becoming more and more common, and research on it has received more and more attention from the academic community [1,2,3]. Its main function is to restrict the forward movement of the tibia, but it plays a certain role in controlling the rotation of the knee joint, and the stress situation is complex [4]. E purpose is Complexity to observe the healing after surgical reconstruction It is not a special continuous layer structure study. Erefore, ligament reinforcement is needed to protect the knee joint and increase the stability of the joint It plays a vital role in human activities.
