The Knee Injury and Osteoarthritis Outcome Score (KOOS) is one of the valid reliable tools for patient-reported assessment knee joint in cases injury or osteoarthritis, before after replacement. aim this study was to evaluate validity reliability Bulgarian version KOOS questionnaire. First, original English translated into Bulgarian, back-translated, pilot-tested clarity acceptance. Then questi...

BACKGROUND Female athletes are at significantly greater risk of anterior cruciate ligament (ACL) injury than male athletes in the same high-risk sports. Decreased trunk (core) neuromuscular control may compromise dynamic knee stability. HYPOTHESES (1) Increased trunk displacement after sudden force release would be associated with increased knee injury risk; (2) coronal (lateral), not sagitta...

OBJECTIVE To examine if unilateral knee injury affects the synovial fluid concentrations of aggrecan fragments, cartilage oligomeric matrix protein (COMP) fragments, stromelysin-1, and tissue inhibitor of metalloproteinases-1 (TIMP-1) in the contralateral uninjured knee. METHODS Synovial fluids from the injured and uninjured knees were obtained at different times in a group of patients after ...

objective(s): the effect of silica nanoparticles (snps) in sport shoes outsoles on the  parameters related to anterior cruciate ligament (acl) injury has not been investigated. the aim of this study was to investigate the effect of shoes outsole containing a composite of thermoplastic elastomer based on styrene-butadiene and silica nanoparticles (tpen shoe) on knee valgus angle (kva) as a risk ...

BACKGROUND To identify and characterize the concomitant ligamentous and meniscal injuries in floating knee. METHODS A total of 37 cases of floating knee were enrolled. Arthroscopic or open surgical examination of the knee, Lachman test, posterior drawer's test, and varus and valgus stress tests under anesthesia were carried out to determine the incidence of knee injury. RESULTS Through arth...

BACKGROUND Knee injuries in football are common regardless of age, gender or playing level, but adolescent females seem to have the highest risk. The consequences after severe knee injury, for example anterior cruciate ligament (ACL) injury, are well-known, but less is known about knee injury prevention. We have designed a cluster randomized controlled trial (RCT) to evaluate the effect of a wa...

To prospectively evaluate the effect of neuromuscular training on the incidence of knee injury in female athletes, we monitored two groups of female athletes, one trained before sports participation and the other not trained, and a group of untrained male athletes throughout the high school soccer, volleyball, and basketball seasons. Weekly reports included the number of practice and competitio...

Anterior cruciate ligament (ACL) injury and patellofemoral pain (PFP) are common sports-related knee injuries. Their consequences include compromised health of the effected individual and substantial financial costs for society. Increased knee abduction or a knee medial to foot position (KMFP), so called “kissing knees”, during weight-bearing activities is reported to be more common in patients...
