Background: Lower extremity injuries are frequently observed in car-to-pedestrian accidents and due to the bumper height of most cars, knee joint is one of the most damaged body parts in car-to-pedestrian collisions.Objective: The aim of this paper is first to provide an accurate Finite Element model of the knee joint and second to investigate lower limb impact biomechanics in car-to-pede...

objectives: to investigate the clinical efficacy of physiotherapy with and without superficial dry needling on patients with knee pain; patellofemoral pain syndrome. methods: a randomized clinical trial conducted in 2015, tehran, iran. of patients with patellofemoral pain syndrome, thirty-four subjects were randomly divided into two groups (17 in each group). group a was subjected to physiother...

the effect of chronic inflammation induced by complete freund's adjuvant (cfa) on anterior blood vessels of knee joint and its diameter was studied. blood flow changes in response to phenylephrine (αl-adrenoceptor agonist) in cfa-treated and contralateral knee joints were observed over a 40-day period, using laser doppler flowmetery (ldf) technique. unilateral injection of cfa (0.2 ml) inc...

conclusions the clinical examination is an important and accurate diagnostic modality for evaluation of traumatic derangement of the knee joint. it is noninvasive, easy, available, and valuable diagnostic modality. the mri is an accurate diagnostic modality. it can be used whenever there is an uncertain indication for arthroscopy. however, costs have to be kept in mind, especially in patients w...

this report describes a rare intra-articular benign tumor, lipoma arborescens, of the knee joint in a 21 year-old female. the patient suffered from left knee joint swelling for five years with occasional pain. swelling was soft and boggy in the suprapatellar area. motion of joint was complete. no abnormality was detected in any laboratory tests. mri showed a large soft tissue density in the sup...

experiments wee performed to evaluate the contralateral effect of adjuvant induced mono arthritis. in these experiments laser doppler imaging (ldi) was used to investigate changes in blood flow. adjuvant was applied to induce chronic inflammation. temperature and knee diameter increased in the first week after administration in the administrated knee joint.substance p (sp) (a neruokinin with a ...

Experiments were carried out on anesthetized adult New Zealand rabbits. Acute joint inflammation was achieved by intra-articular injection of 2% carrageenan. Radiolabelled microspheres were used to measure the effect of acute inflammation on blood flow in the knee joint and establish whether neural influences on blood vessel caliber were affected. Surgical exposure of the posterior joint "capsu...

Beta-2 adrenoceptors in blood vessels are one of the active factors that play a role in regulation of tissue blood flow. in diabetic angiopathy, responsiveness of these receptors is decreased, while that is increased in inflammation. According to these opposite effects, the aim of this study was to investigate the vasodilatory response of knee joint blood vessels to salbutamol (Beta-2 adreno...
