This study is aimed at the analysis of articular contact in a three-dimensional mathematical model of the human knee-joint. In particular the effect of articular contact on the passive motion characteristics is assessed in relation to experimentally obtained joint kinematics. Two basically different mathematical contact descriptions were compared for this purpose. One description was for rigid ...

A three-dimensional analytical model of the knee-joint is presented, taking into account the geometry of the joint surfaces as well as the geometry and material properties of the ligaments and capsule. The position of a large number of points on the joint surfaces is measured and the geometry of these surfaces is then approximated by polynomials in space. The ligaments and capsule are represent...

This study aimed to demonstrate the sensitivity of virtual reality (VR)/motion tracking to detect global functional gait impairment resulting from an emulated knee disability as a prelude to describing mobility changes following lower limb injury/treatment. Participants walked in a figure-8 around two virtual posts placed 6m apart while viewing the computer-generated environment in a helmet-mou...

diagnosis of knee osteoarthritis can be confirmed based on clinical and/or radiological features. the potential of a progressive disease can be prevented or decreased by earlier recognition and correction of associated factors. obesity and alignment especially varus malalignment are recognized factors of a progressive disease. both nonpharmalogical as well as pharmacological modalities of treat...

introduction arthrogryposis multiplex congenita (amc) with incidence of 1 in 3000 of births is characterized by multiple rigid joint and soft-tissue contractures. case presentation we present a case of amc with severe soft tissue and joints contractures, especially joints of lower limb and elbows, bilateral complete dislocation of hips (cdh) and knees (cdk) (type iii), bilateral elbow joint dis...

conclusions this study presented some effects of the pomegranate peel extract in reducing pain and improving clinical signs and symptoms in women with knee oa and might be considered as a complementary medicine in treating oa. results there were no significant differences between the two groups in the mean of age, body mass index (bmi), disease duration and parity before intervention (p > 0.05)...

background and aims: osteoarthritis is one of the most common arthritis in elderly. we evaluated to compare the effect of topical application of eugenia caryophylata extract and topical diclofenac in primary knee osteoarthritis.methods: this randomized double-blind clinical trial study was carried out upon 105 patients with primary knee osteoarthritis. patients were selected randomly and divide...

background intra-articular analgesia is a pain reliever that is frequently administered following arthroscopic knee surgery. objectives the purpose of this study was to compare the efficacy of intra-articular applicationrnof morphine and tramadol on postoperative pain after arthroscopic knee surgery patients and methods for this randomized double blinded clinical trial, 132 patientsrnundergoing...

  Background: The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis.   Methods: The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighte...
