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...

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...

background osteoarthritis (oa) is a multifactorial, disabling and degenerative disease that worsens with age and affects patient’s health-related quality of life (hrqol). objectives the current study aimed to assess if age and comorbidities have an influence on knee oa and knee replacement outcome before and after the surgery. methods a quasi-experimental intervention study was conducted on a s...

background: total knee arthroplasty is a complex procedure aiming to relieve pain and improve function. it is critical to select prosthesis that best cover the bone surfaces. ethnicity may affect fitness of the components mainly designed for caucasian populations. this study aimed to evaluate morphometric features of proximal tibia in iranian population.   methods : during 2013, 150 consecutive...

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...

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 ...

conclusions our findings may be applied by manufacturers to design prostheses more compatible with asian populations. alterations to the shape of components should be considered to provide optimal coverage. patients and methods during 2013, 150 consecutive patients (96 males and 54 females) from the outpatient department of orthopedic surgery of rasoul akram hospital with knee ct scans were stu...
