Abstract

Because of the intense competition, table tennis requires players to bear a strong physiological load, which increases the risk of sports injury. Anterior cruciate ligament (ACL) is an important structure of the knee joint to maintain forward stability and rotational stability and is also a common sports injury in table tennis players. ACL has poor self-repair ability after injury. Therefore, the purpose of this study is to provide a more comprehensive, reliable, and representative theoretical basis for the diagnosis and rehabilitation of anterior cruciate ligament injury in table tennis players, and three-dimensional reconstruction of ACL using dual-source computed tomography (DSCT) combined with deep learning was conducted. For this purpose, a number of table tennis players with ACL injuries were collected, and each patient underwent arthroscopic anterior cruciate ligament reconstruction. DSCT scanning was performed on several knee joints, the 3D model of the knee joint was reconstructed using a CT image postprocessing workstation, and the medial wall of the femoral lateral condyle was reconstructed, as well as the reconstructed single tract of bony canal, tibial plateau, and bony canal. Then, the Lysholm score was used to score the cases, with scores greater than 75 as the excellent group and below 75 as the poor group. The relative positions of the central points of the femoral and tibial canals were marked and measured. The results were as follows: 3D-CT reconstruction could clearly reflect the situation after anterior cruciate ligament reconstruction. In clinic, it is used to evaluate the relationship between bone tunnel location and graft shape so as to guide the surgeon to improve the operation.

Highlights

To promote the development of medical technology is the most meaningful help of artificial intelligence to human beings so that machines, algorithms, and big data can serve human health and smart medical treatment will become the core technology for people to resist diseases and prolong their lives in the future
In China, the influence of ACL injury on athletes cannot be ignored, and its incidence has been on the rise. e knee joint anatomical structures and characteristics of it in the human body function position that knee injury to become one of the easiest and most common injuries; an ACL injury is the most common in clinic, cruciate ligament plays an important role in maintaining the stability of the knee joint [1,2,3], and anterior cruciate ligament injury is common
Due to its own histological characteristics and poor blood supply of the ACL, the central ligament and the bone attachment area of the ligament are deficient in Journal of Healthcare Engineering blood supply [5]. erefore, after the ACL fracture, the original state cannot be restored depending on its own characteristics, which tends to lead to the functional instability of the affected limb [6, 7] and cannot meet the life needs of patients

Summary

Introduction

To promote the development of medical technology is the most meaningful help of artificial intelligence to human beings so that machines, algorithms, and big data can serve human health and smart medical treatment will become the core technology for people to resist diseases and prolong their lives in the future. According to domestic research reports, the total incidence of anterior cruciate ligament fracture in China is 0.47% (32/6810). According to the Lysholm score, the enrolled patients were divided into the excellent knee function group and the poor knee function group, and there was no significant difference between the femoral and tibial insertion positions of the knee at the operation side between the two groups, so as to explore the imaging parameters reflecting the functional recovery after anterior cruciate ligament reconstruction. En, the positions of the tibia and femur bone tunnel were measured to study the differences of the positions of the femur and tibia bone canal under different clinical curative effects and the corresponding radiation parameters in order to provide theoretical support for the surgeons in the clinical operation of an anterior cruciate ligament injury in table tennis players in the future According to the Lysholm score, the enrolled patients were divided into the excellent knee function group and the poor knee function group, and there was no significant difference between the femoral and tibial insertion positions of the knee at the operation side between the two groups, so as to explore the imaging parameters reflecting the functional recovery after anterior cruciate ligament reconstruction. en, the positions of the tibia and femur bone tunnel were measured to study the differences of the positions of the femur and tibia bone canal under different clinical curative effects and the corresponding radiation parameters in order to provide theoretical support for the surgeons in the clinical operation of an anterior cruciate ligament injury in table tennis players in the future
