background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...

background: osteoarthritis is a disabling musculoskeletal disease with no definite treatment. this study compared the effect of platelet-rich plasma (prp) and transcutaneous electrical nerve stimulation (tens) plus exercise in the treatment of patients with knee joint osteoarthritis.   methods : 54 eligible patients with knee osteoarthritis were randomly allocated into two groups. (irct20121106...

normal axial alignment restoration in lower extremities is crucial for surgeons performing reconstructive surgeries. since reference normal values of axial alignment are affected by age, sex, and ethical issues, we tried to scrutinize these parameters in iranian adults and compare them with normal values in literatures. through a cross-sectional design, standing axial alignment views of lower e...

congenital dislocation of the knee (cdk) is a rare disorder. we report the case of a 7-year-old girl with bilateral knee stiffness, marked anterior bowing of both legs, and inability to walk without aid. radiologic investigation revealed bilateral knee joint dislocation accompanied by severe anterior bowing of both tibia proximally and posterior bowing of both femur distally, demonstrating a co...

Abstract This research is stressed at time and space characteristics (centre of gravity movements) in female pole vault. There are involved 19 vault jumpers with sport performance 380 – 483 cm, divided on 2 different groups; higher lower level from the point performance. We found that parameters reached better results high phases hanging lifting. It coursed by transmission after take-off work p...

Skeletal loading during growth may be one way of increasing bone mass early in life. We hypothesized that children randomized to a jumping program (25 jumps/day from a 45-cm box, 5 days/week for 12 weeks) would have greater increases in hip and spine bone mineral content (BMC) and 4% distal tibia volumetric bone density than children randomized to the control group. Our secondary hypothesis was...

Zug, George R. Anuran Locomotion—Structure and Function, 2: Jumping Performance of Semiaquatic, Terrestrial, and Arboreal Frogs. Smithsonian Contribution to Zoology, number 276, 31 pages, 9 figures, 15 tables, 1978.—Frogs evolved as jumping machines. The earliest recognized anuran fossil possessed a foreshortened body and elongated hindlimbs, primary adaptations for jumping. The majority of ext...

Recent evidence has suggested that relationship between approach speed and distance jumped may not be linear. The aims of this study were (1) to test the hypothesis that using a short approach (6-8-10-12 strides) of increasing length, performance variables will be non-linearly related to distance jumped, (2) to investigate the nature of these relationships for a group of long jumpers and indivi...

multiplanar or global laxity in arthritic knee is rare , most of this patients have neuromuscular disorder (post poliomyelitis , spinal dystrophy) or history of knee trauma. ligament insufficiency and severe bone loss is significant in this patient. the estimated prevalence for the concurrence of charcot marie-tooth (cmt) with myasthenia gravis (mg) suggests an extremely rare event. we have pre...
