BACKGROUND The mechanisms of anterior cruciate ligament injury in basketball are not well defined. PURPOSE To describe the mechanisms of anterior cruciate ligament injury in basketball based on videos of injury situations. STUDY DESIGN Case series; Level of evidence, 4. METHODS Six international experts performed visual inspection analyses of 39(More)
BACKGROUND The geometry of the tibial plateau is complex and asymmetric. Previous research has characterized subject-to-subject differences in the tibial plateau geometry in the sagittal plane on the basis of a single parameter, the posterior slope. We hypothesized that (1) there are large subject-to-subject variations in terms of slopes, the depth of(More)
Videos of sports injuries can potentially provide valuable information on non-contact ACL injuries. However, only the un-validated simple visual inspection approach has, so far, been used. Therefore, the purpose of this study was to test the accuracy and precision of researchers in estimating kinematics from video sequences of situations that typically lead(More)
Women are more prone to anterior cruciate ligament (ACL) injury during cutting sports than men. The purpose of this study was to examine knee kinematic and ground reaction forces (GRF) differences between genders during cutting. Male and female athletes performed cutting trials while force platform and video data were recorded (180 Hz). Differences (p < .(More)
The incidence of noncontact anterior cruciate ligament injuries in young to middle-aged athletes remains high. Despite early diagnosis and appropriate operative and nonoperative treatments, posttraumatic degenerative arthritis may develop. In a meeting in Atlanta, Georgia (January 2005), sponsored by the American Orthopaedic Society for Sports Medicine, a(More)

Objective: To determine if anterior cruciate ligament (ACL) injuries in female(More)
I njuries to the anterior cruciate ligament (ACL) of the knee are common in athletes and have serious sequelae, including increased risk of early-onset posttraumatic osteoarthritis regardless of the treatment administered. 16 Injury rates as high as 2.8 and 3.2 injuries per 10 000 athlete exposures have been reported in women's collegiate sports. 17 The(More)
UNLABELLED A femoral load-cell was installed in twelve fresh-frozen knee specimens from cadavera, to measure the resultant force at the femoral origin of the posterior cruciate ligament during a series of tibial-loading tests. The posterior cruciate ligament was removed, and a ten-millimeter-wide bone-patellar ligament-bone graft was inserted. The knee was(More)
BACKGROUND Anterior cruciate ligament (ACL) injuries are disabling and are associated with the early onset of posttraumatic osteoarthritis. Little is known regarding the incidence rate of first-time noncontact ACL injuries sustained during athletic events and how they are independently influenced by level of competition, type of sport, and the participant's(More)
OBJECTIVE To investigate the degree to which concussion history and postconcussive symptoms are associated with cortical morphology among male hockey players. STUDY DESIGN Male subjects (n = 29), ranging in age from 14 to 23 years (mean 17.8 years), were recruited from preparatory school and collegiate ice hockey teams and underwent neuroimaging and(More)
