case a 13-year-old boy presented to the ski clinic following a fall and a possible twisting of his right knee. he was not able to bear any weight on his right leg and was experiencing pain in the medial aspect of his right knee. his past medical and surgical histories were unremarkable and he was otherwise in good health. physical examination revealed no ecchymosis or effusion. he had moderate ...

introduction: low-level laser therapy (lllt) is thought to have analgesic and biomodulatory effects. our objective was to assess the pain-relieving effect of lllt and possible changes in joint stiffness and disability of patients with knee osteoarthritis (koa) and compare it to the more commonly used modality; therapeutic ultrasound(us). methods: 37 patients with mild or moderate koa were rando...

introduction: knee osteoarthrosis is one of the most debilitating diseases. prolotherapy includes intraarticular injection of various drugs to decrease inflammation. injection of intradiscal o2-o3 has reduced pain and disability of patients with low back pain due to prolapsed lumbar disk. objective: to compare the effect of intraarticular injection of ozone and steroids in improvement of clinic...

Background: The maintenance of deformity in the ankle and hindfoot after correction of knee deformity following kneearthroplasty may cause abnormal tension in the knee and patient dissatisfaction. The aim of this study was to determinethe effect of knee arthroplasty on the hindfoot alignment in patients with severe genu varum and valgum.Methods: A total of 84 patients with pri...

primary knee osteoarthritis (oa) is one of the degenerative diseases that destroy auricular cartilage within knee joint and cause pain, varies deformity, decrease knee function. total knee arthroplasty (tka) is an effective intervention in order to relieve pain, improve function and qol (quality of life) in patients with severe osteoarthritis of the knees that have different degrees of varus de...

background: knee osteoarthritis (oa) is the most common musculoskeletal disease among old individuals which affects ability for sitting on the chair, standing, walking and climbing stairs. our objective was to investigate the short and long-term effects of the most simple and the least expensive exercise protocols in combination to conventional conservative therapy for knee oa.   methods : it w...

Ultrahigh molecular weight polyethylene (UHMWPE) has remained the primary polymer used in hip, knee and shoulder replacements for over 50 years. Recent case studies have demonstrated that catastrophic fatigue fracture of the polymer can severely limit device lifetime and are often associated with stress concentration (notches) integrated into the design. This study evaluates the influence of no...

A finite element (FE) model of the below-knee residual limb and prosthetic socket was created to investigate the effects of parameter variations on the interface stress distribution during static stance. This model was based upon geometric approximations of anthropometric residual limb geometry. The model was not specific to an individual with amputation, but could be scaled to approximate the ...

Patellar tendon moment arm length (PTma) changes at different knee flexion angles have not been determined in invivo studies. We aimed to determine PTma in four different knee angles using Magnetic Resonance Imaging (MRI) topredict in vivo changes in the moment arm length from different knee angles during running.PTma was measured as the perpendicular distance from muscle–tend...
