“…ACL is the core ligament that guides the movement of the knee joint. Its main function is to restrict the forward movement of the tibia, but it also plays a certain role in controlling the rotation of the knee joint, and the stress situation is complex [4]. e key part of its mechanical conduction, the tibia stop, has become the focus of biomechanical research of ligaments.…”

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.

Article informationBackground: Meniscal lesions are the commonest lesions in the knee, and usually caused by athletic activities. Meniscal lesions diagnosis may need costly imaging modalities like magnetic resonance imaging [MRI]. However, MRI is not available in all medical facilities, especially peripheral and rural continents. Thus, there is a need for a readily available imaging tool. Knee ultrasound may be used as diagnostic modality as it is devoid of economic burden of MRI. Aim of the work:The current work aimed to estimate the diagnostic accuracy of knee ultrasound and to correlate it with the results of MRI for diagnosis of knee meniscal lesions.Patients and methods: Fourty patients with acute or chronic knee pain, swelling or movement restrictions were included. All were assessed by referral physician and submitted to knee ultrasound and MRI. Then results of ultrasound were correlated with that of MRI and diagnostic accuracy measures of ultrasound were calculated [sensitivity, specificity, positive predictive value [PPV], negative predictive value [NPV] and overall accuracy].Result: Out of included patients, 28 were males. Their mean age was 36.7 ± 14.4 years [ranged from 15 to 60 years]. The ultrasound detected meniscal tear in 90%, degeneration in 47.5%, Para-meniscal cyst in 25% and discoid meniscus in 40%. The MRI detected meniscal tear in 80%, degeneration in 65%, para-meniscal cyst in 25% and discoid meniscus in 37.5%. For meniscal tear, the ultrasound had 83.3% sensitivity, 50.0% specificity, 93.7% PPV, 25.0% NPV and overall accuracy of 80.0%. Otherwise, the overall accuracy was 75.0% for degenerative changes and 95.0% for para meniscal cyst. Finally, it was 67.5% for discoid meniscus. Conclusion:Ultrasound has shown reasonable diagnostic accuracy in detecting meniscal lesions. It could be used as a screening tool to prevent unnecessary and costly MRI.
