The relationships of gender, age and training to the incidence of anterior cruciate ligament (ACL) injury are pivotal to developing a comprehensive neuromuscular and proprioceptive training programme to decrease ACL injuries in female athletes. A prophylactic neuromuscular and proprioceptive training programme may have direct benefit in decreasing the number of ACL injuries in female athletes. ...

BACKGROUND The biomechanical effects of lateral meniscal posterior root tears with and without meniscofemoral ligament (MFL) tears in anterior cruciate ligament (ACL)-deficient knees have not been studied in detail. PURPOSE To determine the biomechanical effects of the lateral meniscus (LM) posterior root tear in ACL-intact and ACL-deficient knees. In addition, the biomechanical effects of di...

PURPOSE The purpose of this study was to identify neuromuscular training intervention programs that significantly reduced the incidence of noncontact anterior cruciate ligament (ACL) injury rates in female adolescent athletes. METHODS A systematic search of PubMed was conducted to determine the outcome of ACL neuromuscular retraining programs in a specific population. The inclusion criteria w...

BACKGROUND Loss of proprioceptive function occurs after anterior cruciate ligament (ACL) rupture. Clinical, motor, and proprioceptive function is known to improve after ACL reconstruction but does not return to normal. While histological studies of human ACL allografts have been unable to demonstrate mechanoreceptor reinnervation, animal data suggest that reinnervation may occur when an autogra...

BACKGROUND Compressive and quadriceps forces have been associated with noncontact anterior cruciate ligament (ACL) injury. The purpose of this study was to quantify the relative importance of each load component during noncontact ACL injury. HYPOTHESIS We hypothesized that the introduction of a quadriceps force lowers the axial compressive force threshold to produce ACL injury. STUDY DESIGN...

ATHLETIC THERAPY TODAY ATHLETIC THERAPY TODAY MARCH 2006  11 chondral-surface damage, and early onset of osteoarthitis.5-8 It has been reported that individuals suffering acute knee injury, such as ACL injury, are 7.4 times more likely to develop knee osteoarthritis than those with no history of knee injury.9 Ultimately, the disability associated with ACL injury can lead to reduced physical ac...

What are the most common causes of anterior cruciate ligament (ACL) injury in athletes? The most common causes for ACL injury in athletes are noncontact, twisting injuries that involved a pivoting motion. For example, in sports such as soccer, athletes frequently perform motions that plant and twist the lower extremities, putting those who play soccer at one of the highest likelihoods of ACL in...

BACKGROUND Internal tibial rotation is a risk factor for anterior cruciate ligament (ACL) injury. The effect of restraining tibial rotation (RTR) to prevent ACL injury during single-leg landing is not well understood. We aimed to investigate the effect of impact load and RTR on ACL injury with respect to flexion angle. We hypothesized that RTR could protect the knee from ACL injury compared to ...

BACKGROUND Lesser metatarsophalangeal joint (MTPJ) instability is a common complaint. The role each of the collateral structures play in maintaining joint stability is unknown. METHODS Twenty-six fresh-frozen cadaver lesser MTPJ's were tested for instability with the amount of force necessary to translate the joint 3 mm dorsally. Specimens were tested with 1) intact collateral ligaments, 2) t...

background: articular cartilage injuries are a common clinical problem at the time of acl reconstruction with an incidence rate of 16-46%. good results of acl reconstruction combined with the treatment of chondral lesions have been published in some studies. method: after statistical analysis 30 patients were selected and divided in 2 groups. theffirst group consisted of 15 patients wite isolat...
