Posterior cruciate ligament (PCL) injuries account for 3% to 23% of knee injuries. In a trauma setting, they are responsible for up to 40% of all knee ligamentous injures. However, because they are often asymptomatic, PCL injuries are underdiagnosed. In a review of 19,530 athletic injuries occurring over a 10-year period, anterior cruciate ligament (ACL) injuries occurred 31 times more often th...

Head injury without loss of consciousness is seldom accompanied by grave complications. We report the case of an 18 year old cyclist who was struck by a car in a minor road traffic accident, suffered minor head injury without loss of consciousness, and died unexpectedly seven weeks later with vomiting and coma. Necropsy revealed an expanding cerebellar infarct and vertebral artery thrombosis, s...

Injuries to the knee, including intra-articular fractures, ligamentous ruptures, and meniscal and articular cartilage lesions, are commonplace within sports. Despite advancements in surgical techniques and enhanced rehabilitation, athletes returning to cutting, pivoting, and jumping sports after a knee injury are at greater risk of sustaining a second injury. The clinical utility of objective c...

The anterior cruciate ligament (ACL) is an important stabilizer of knee motion. Injury of the ACL can lead to substantial disability; an accurate diagnosis of ACL injury is vital in both short-term and long-term patient care. Magnetic resonance (MR) imaging has emerged as the study of choice to evaluate the status of the ACL and other associated structures in the knee. Sagittal MR images have b...

Ankle injuries are common in sports, and the ankle sprain is the most common of ankle injuries, but there are many injuries that can mimic a sprain. In the skeletally immature athlete, bone injuries, particularly those that affect the physis, are more likely to occur than a ligamentous injury. Knowledge of relevant anatomy, physical exam, and appropriate imaging can assist the primary care prov...

BACKGROUND Generalized joint laxity has been linked to ligamentous injuries such as anterior cruciate ligament tear and ankle sprain. PURPOSE/HYPOTHESIS The purpose of this study was to investigate generalized joint laxity and incidence of ligament injuries in high school-aged female volleyball players. It was hypothesized that volleyball players with a past history of sprains would have incr...

The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posterior stabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCL injuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has become an important and validated objective measure...

Knee stability during a functional assessment of the stop-jump task is a key factor to determine if an athlete is adequately rehabilitated after knee ligamentous injury. This study aimed to investigate knee stability due to the effect of anticipation on landing maneuvers during planned and unplanned stop-jump tasks. Knee kinematics of ten healthy male participants were collected using an optica...

An association between lateral patellar dislocation (LPD) and medial collateral ligament injury (MCL) has recently been demonstrated on MRI. The same valgus injury that disrupts the femoral MCL insertion can also cause a simultaneous MPFL tear at its femoral insertion, due to the close anatomical relationship of both ligamentous structures. Valgus laxity due to MCL-deficiency increases the Q-an...
