BACKGROUND Most lesions of articular cartilage do not heal spontaneously and may lead to secondary osteoarthritis. It is not known whether the optimistic reports on the short and long-term results of several different cartilage repair techniques are based on sound methodological quality. METHODS We performed a literature search in MEDLINE, CINAHL, the(More)
BACKGROUND The geometry of the tibial plateau has been largely ignored as a source of possible risk factors for anterior cruciate ligament injury. Discovering the anterior cruciate ligament injury risk factors associated with the tibial plateau may lead to delineation of the existing sex-based disparity in anterior cruciate ligament injuries and help(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)
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)
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)
OBJECTIVE Neuromuscular performance increases rapidly in males throughout pubertal development, whereas no similar neuromuscular spurt occurs in females. This fact may underlie neuromuscular imbalances related to increased risk of injury in females. The hypothesis: female athletes would demonstrate mismatched landing force to power production compared with(More)
BACKGROUND Methods for analyzing the mechanisms of injuries in sports from video sequences of injury situations are so far limited to a simple visual inspection, which has shown poor accuracy. PURPOSE To investigate whether a new model-based image-matching technique could successfully be applied to estimate kinematic characteristics of three typical(More)
BACKGROUND Detailed descriptions of meniscus and articular cartilage lesions associated with anterior cruciate ligament injury have not been presented in the literature. Our goal was to determine the associations between patient sex, age, and surgical delay and the frequency and location of meniscus and articular cartilage lesions seen at the time of the(More)
BACKGROUND A diverse range of values for the mechanical properties of the human patellar tendon has been reported in the literature. Donor age has been excluded as a factor that causes this disparity. However, the effects of donor sex and tissue mass density on the mechanical properties of the patellar tendon have not been established. More importantly,(More)
