Abstract
Patterns of Meniscal Damage Associated with Acute ACL Rupture
Highlights
Anterior cruciate ligament (ACL), as a primary stabilizing structure of knee is the most common disrupted ligament in acute trauma in the US every year [1,2]
This study was conducted to determine the patterns of meniscus damage associated with ACL rupture and identify the commonest type of meniscus damage in our population that is associated with ACL tear
The collected data included the presence or absence of meniscal tear, the type of meniscal tear diagnosed by Magnetic resonance imaging (MRI) or arthroscopy, the time of the initial ACL injury and the time of meniscal tear, the duration between ACL rupture and reconstruction surgery, age, gender, mode of injury and level of sports activity performed, height, weight
Summary
Anterior cruciate ligament (ACL), as a primary stabilizing structure of knee is the most common disrupted ligament in acute trauma in the US every year [1,2]. The menisci play a crucial role in the dynamics of the knee. Their shape, attachment, and material properties contribute substantially to joint alignment and load transmission by distributing both tensile and compressive forces. Damage to the menisci can influence proprioception, stability, and mobility of the knee [3,4]. Risk factors for meniscal tears include prolonged or repeated deep knee bending, obesity, and sports [5]. As seen in alpine sports, involves complex dynamics, which can damage singular or multiple tissue structures of the knee [5,6]. Meniscal tears are typically thought to be initiated by coupled compression and twisting movements [7,8] which can accompany high-energy maneuvers such as cutting, jumping, and landing during sporting events [9]
