“…31 While isolated ligamentous injury of the knee often involves the MCL, traumatic sports injuries can affect multiple knee ligaments. 1 Concomitant injury to the posterolateral structures is often unrecognized in patients with multiple ligament or combined ligament disruptions. 12,22 Abnormal varus laxity arising subsequent to injuries of the LCL and other posterolateral structures has been shown to increase stress on cruciate ligament grafts, and has been implicated as one of the causes of failed cruciate ligament reconstructions.…”

T he passive stability of the knee is primarily provided by a complex system of intra-and extra-articular ligaments that resist anterior and posterior translation, abnormal tibial rotation, and varus and valgus rotation. Functionally, the medial collateral ligament complex (MCL) acts as the primary restraint to valgus rotation of the tibia, providing as much as 80% of the restraining force to valgus loads. 11 The lateral collateral T T STUDY DESIGN: Controlled laboratory study. T T BACKGROUND:Varus knee instability arising from lateral collateral ligament (LCL) injury increases stress on cruciate ligament grafts, potentially leading to failure of reconstructed ligaments. In contrast to the medial collateral ligament (MCL), little is known about the structural properties of the LCL. T T OBJECTIVES:To compare the tensile properties of the LCL and MCL complex of the human knee joint. T T METHODS:Ten fresh-frozen cadaveric knees (mean  SD age, 81  11 years), free of gross musculoskeletal pathology, were obtained. Following dissection, the length, width, and thickness of the ligaments were measured using calipers, and bone-ligament-bone preparations were mounted in a uniaxial load frame. After preconditioning, specimens were extended to failure at a rate of 500 mm/min (approximately 20%/s). Force and crosshead displacement were used to calculate structural properties, including stiffness, yield strength, ultimate tensile strength, and failure energy. T T RESULTS:The fan-shaped MCL was significantly longer (60%; P<.001), wider (680%; P<.001), and thinner (19%; P = .009) than the cord-like LCL.The LCL failed at either the fibular attachment (n = 6) or midsubstance (n = 4), while failure of the MCL primarily occurred at the femoral attachment (n = 7). Although the ultimate tensile strength of the MCL (mean  SD, 799  209 N) was twice that of the LCL (392  104 N; P<.001), there was no significant difference in stiffness of the ligaments (MCL, 63  14 N/mm; LCL, 59  12 N/ mm). 30 During normal gait, the LCL is the primary passive structure resisting the knee adduction (varus) moment, which has been implicated in the progression of knee osteoarthritis. T T CONCLUSIONS: 31While isolated ligamentous injury of the knee often involves the MCL, traumatic sports injuries can affect multiple knee ligaments.1 Concomitant injury to the posterolateral structures is often unrecognized in patients with multiple ligament or combined ligament disruptions.12,22 Abnormal varus laxity arising subsequent to injuries of the LCL and other posterolateral structures has been shown to increase stress on cruciate ligament grafts, and has been implicated as one of the causes of failed cruciate ligament reconstructions. 12,19 Unlike the MCL, animal models have demonstrated that the LCL heals poorly when torn, 20 and, consequently, surgical repair or reconstruction of the LCL is often advocated with acute grade III injuries, particularly when multiple posterolateral structures are involved.14 Although sparse data are available concerning the c...

“…A retrospective cross-sectional study conducted among students of physical education at Umm Al-Qura University found that right-sided injures accounted for 70% of cases, whereas left-sided injuries accounted for 30% [10]. In addition, another study reported that right-sided injuries were the most common (56.9%) [15].…”

The purpose of this study was to study the association of anterior cruciate ligament (ACL) injury with meniscal, collateral ligament, and bone injuries using magnetic resonance imaging (MRI) for clinical correlation during ACL repair. Methods This was a retrospective cohort study conducted on 136 patients diagnosed with ACL injury by MRI at King Abdulaziz University Hospital (KAUH) between September 2010 and September 2018. Results The medial meniscus was injured in approximately half (49.3%) of patients, while the lateral meniscus was injured in 16.2%. Regarding collateral ligament injuries, the medial collateral ligament was injured in six patients (4.4%), the lateral collateral ligament in four patients (2.9%), and both collateral ligaments in three patients (2.2%). There was a significant relationship between the age group and the side of ACL injury (P<0.05) but not between the age group and the presence of an associated injury. Conclusion There was no significant relationship between ACL injury and menisci, collateral ligament, or bone injury.

“…However, chronic repair of collateral ligaments and posterolateral structures is insufficient due to excessive scar tissue and difficulty in identifying anatomic structures [12, 22, 23]. Moreover, chronic multiligament knee injuries may change limb alignment and generate knee deformities [3, 19]. There is a lack of published studies which directly compare acute and chronic surgery in patients with KDs, to indicate improvement in clinical results after acute surgery.…”
