Abstract:

Purpose: To analyze MR direct and indirect signs for knees with anterior cruciate ligament (ACL) partial or complete tear. Material and Methods: According to documented MR direct and indirect signs for ACL tear, we retrospectively reviewed the incidence of those signs in 15 partial ACL tear and 17 complete ACL tear patients. The findings were also compared with duration of injury (less or more than 6 weeks, as acute or chronic stages). Results: A residual straight and tight ACL fiber in at least one pulse sequence was more frequently detected in partial ACL tears. The empty notch sign, a wavy

Background: Medial meniscus ramp tears are present in 22.9–40.8% of anterior cruciate ligament tears. The diagnosis of ramp tears is difficult on MRI, with sensitivity reported around 48%, which has recently emphasized the importance of proper arthroscopic probing for ramp tears. Methods: A prospective evaluation was performed on patients undergoing a single bundle ACL reconstruction to assess patient demographics, posterior tibial slope, posterior cruciate ligament angle, Lachman’s exam, and rotational instability to determine secondary findings associated with medial meniscal ramp tears.

Abstract:

Background: The knee joint is highly susceptible to injuries, particularly from sports and trauma, making Magnetic Resonance Imaging (MRI) a valuable tool for diagnosing musculoskeletal disorders due to its excellent soft tissue contrast and multiplanar capabilities. The anterior cruciate ligament (ACL) is the most frequently injured and reconstructed ligament in the knee, often sustaining damage alongside other structures such as meniscal and collateral ligaments. MRI effectively identifies these associated injuries, although diagnosing meniscal tears can be particularly difficult when the AC

Abstract:

BACKGROUND Re-tear rates in pediatric and adolescent patients undergoing ACL reconstruction are higher than the general adult population. This has been postulated to be due to many reasons; one of which is participation in high risk activities. Athletes in professional sports are at increased risk of re-injury as well with high activity levels and often face additional pressure to return to sports quickly. The purpose of the study was to analyze ACL re-tear rates across male professional sports leagues in athletes following ACL reconstruction and return to play at the professional level to det

Abstract:

Background: Anterior cruciate ligament (ACL) rupture is the most common ligament injury treated surgically by orthopaedic surgeons. The gold standard for the treatment of the majority of primary ACL tears is ACL reconstruction. However, novel methods of repair, such as bridge-enhanced ACL repair (BEAR), are currently being investigated as alternatives to reconstruction. To assess patients for midsubstance repair suitability, clarify the prognostic implications of injury location and damage, and evaluate the results of a repair technique, it is important to have a baseline classification system

Background: The knee is one of the complex joints in the human body and consists of several internal structures that may lead to the emergence of symptoms of knee injuries [1]. The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee that is located in the middle of the knee and runs from the femur (thigh bone) to the tibia (shin bone). It prevents the tibia from sliding out in front of the femur. Together with posterior cruciate ligament (PCL) it provides rotational stability to the knee [2].

Abstract:

Background: Anterior cruciate ligament (ACL) tears are frequently associated with meniscal injury. Numerous authors have described associations between the presence of a meniscal tear at the time of ACL reconstruction and time to surgery and number of instability episodes1-3. The purpose of this study was to evaluate the relationship between age and the presence of a meniscal tear at the time of ACL reconstruction in children and adolescents. Methods: A single-institution retrospective review was performed of consecutive pediatric and adolescent patients who underwent ACL reconstruction over a

Abstract:

Anterior cruciate ligament (ACL) ruptures are prevalent knee injuries, with approximately 200,000 ruptures annually, and treatment costs exceed USD two billion in the United States alone. Typically, the initial detection of ACL tears and anterior tibial laxity (ATL) involves manual assessments like the Lachman test, which examines anterior knee laxity. Partial ACL tears can go unnoticed if they minimally affect knee laxity; however, they will progress to a complete ACL tear requiring surgical treatment. In this study, a computational finite element model (FEM) of the knee joint was generated t

Abstract:

Introduction: An anterior cruciate ligament (ACL) is frequently injured among athletes. ACL injuries occur due to strong contact or indirect knee trauma, causing the enlarging or destroying of non-contractile, and elastic soft-tissue articular structures. Aims: An anterior cruciate ligament injury is the most injured among young athletes. It could be a complete or partial tear. This study aimed to evaluate the role of MRI and physical examination in diagnosis of anterior cruciate ligament tears among athletes. Method: The data on anterior cruciate ligament tears were collected retrospectively

Abstract:

One of the most common knee injuries is ligament tear, which may initially manifest as an osseous injury in radiographs. Radiologists should therefore be able to recognize ligament tears of the knee as osseous abnormalities in images. This review focuses on the imaging features of knee ligament injuries and their related osseous injuries: anterior cruciate ligament (ACL) tear with Segond fracture; associated marrow contusion; ACL avulsion fracture; posterior cruciate ligament (PCL) tear with osseous avulsion of the ligament including arcuate sign; reverse Segond fracture; PCL avulsion fracture
