the clinical use of prp therapy in the practical setting of orthopaedic fields is increasing partly because of the accessibility of devices that are used in outpatient preparation and delivery. another reason is the strong advertisement of prp procedures as the ultimate treatment and novel technology for knee problems by a few orthopaedic surgeons based on claims of abundant scientific evidence...

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...

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...

background: the aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3d reconstructive ct scan imaging. methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. preoperatively, all the patients underwent a ct scan according to a standard prot...

objectives: the aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how total knee replacement (tkr) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. methods: two-dimensional kinematic gait pattern of 10 participants were collected before and after the tkr surgery, using a ...

osteoarthritis (oa) a common disease of aged population and one of the leading causes of disability. incidence of knee oa is rising by increasing average age of general population. age, weight, trauma to joint due to repetiting movements in particular squatting and kneeling are common risk factors of knee oa. several factors including cytokines, leptin, and mechanical forces are pathogenic fact...

introduction: there are differences in the pattern of the knee joint formation of the studied species. according to the small number of studies which focused chronologically on the avian knee histomorphogenetic events, its “morphogenetic pattern” is hard to be proposed. the present work was designed to identify the sequential events of the knee formation in the partridge embryo. regarding to di...
