background fractures of the knee account for about 6% of all trauma admissions. while its management is mostly focused on fracture treatment, it is not the only factor that defines the final outcome. objectives this study aimed to study objective and subjective outcomes after proximal tibial versus distal femoral fractures in terms of knee instability and health-related quality of life. patient...

prosthetic joint infection (pji) is a serious complication of total knee arthroplasty (tka). control of infection after a failed two-stage tka is not always possible, and the resolution of infection may require an above-knee amputation (aka) or a the-knee (kf). the purpose of this review is to determine which treatment method (aka or kf) yields better function and ambulatory status for patients...

abstract  background: in the recent decade, many primary total knee arthroplasties have  been carried out in iran and the number of revision cases is expected to rise with the  aging population. the aim of this study was to report the outcome of revision surgery  in the country and make a comparison between the outcome of revision and that of  the primary arthroplasty.  methods: retrospectively...

purpose: over the past 20 years, the center of pressure (cop) has been commonly used as an index of postural stability in standing. while many studies investigated cop excursions in patients with knee osteoarthritis and healthy individuals, no comprehensive analysis of the differences in their postural sway pattern exists. the present study aimed to review the previously published studies conce...

objectives: knee osteoarthritis (oa) is a leading cause of disability in older adults. in current study, the effects of three types of orthoses on pain reduction were evaluated in oa patients in iran. methods & materials: in this prospective clinical trial, thirty six patients consisting of 11 men and 25 women with age (mean±sd) of 54.56±2.82 years and diagnosis of mild to moderate knee oa incl...

conversion of knee arthrodesis to total knee arthroplasty is a difficult procedure accompanied by many complications due to soft tissue and extensor mechanism contracture and bone defects. we report two cases of distal femur osteosarcoma that had been undergone wide resection arthrodesis initially. arthrodesis was converted to total knee arthroplasty with hinged prosthesis after many years. we ...

objectives: patients suffering from mild to moderate knee osteoarthritis may be treated with unloader knee orthoses or laterally wedged insoles. the aim of this study was to identify and compare the effects of two orthoses in these patients. methods: 56 patients with medial compartment knee oa were evaluated when wearing an unloader knee orthosis and insoles with a 6° lateral wedge which were r...

tuberculosis (tb), once a disease confined to undeveloped or developing nations is currently in resurgence, which is attributable to pandemic human immunodeficiency virus (hiv) infection and immigration from endemic areas. tuberculous arthritis is difficult to diagnose early because of its atypical insidious clinical manifestations and nonspecific imaging findings. tb is also known as the ‘grea...

background : biomechanical factors are known to be important in knee osteoarthritis (oa) development and progression. this study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group.   methods: 16 females (10 with mild and 6 with moderate medial knee osteoarthr...
