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...

background: chondromalacia patella is the most common cause of mechanical knee pain in young women. q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. objective: to identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and q angle with age at onset of disease. methods: all patient...

Background: Chondromalacia patella is the most common cause of mechanical knee pain in young women. Q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. Objective: To identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and Q angle with age at onset of disease. Methods: All pa...

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...

  Background: Knee malalignment is an important modifiable cause of osteoarthritis (OA). Surgical therapeutic procedures depend on proper knee alignment assessment. The purpose of this study was to compare knee alignment parameters between double and single leg weight-bearing radiographs and to evaluate the reproducibility of inter- and intra-observer measurements. Methods: One hundred eight p...

The gold standard for measuring knee alignment is mechanical axis determined using full-limb radiographs (FLR). Measurement of joint alignment using antero-posterior (AP) knee radiographs is more accessible, economical and involves less radiation exposure to the patient compared with using full-limb radiographs. The aim of this study was to compare and assess the reproducibility of knee joint a...

BACKGROUND The association between knee alignment and knee pain in knee osteoarthritis (OA) is unclear. High tibial osteotomy, a treatment option in knee OA, alters load from the affected to the unaffected compartment of the knee by correcting malalignment. This surgical procedure thus offers the possibility to study the cross-sectional and longitudinal association of alignment to pain. The aim...

Dynamic knee alignment is speculated to have a stronger relationship to medial knee loading than radiographic alignment. Therefore, we aimed to determine what frontal plane knee kinematic variable correlated most strongly to the knee adduction moment. That variable was then compared with radiographic alignment as a predictor of the knee adduction moment. Therefore, 55 subjects with medial knee ...

Purpose: Changes in lower extremity alignment in individuals with abnormality of this segments are unclear. The present study aimed to compare lower extremity alignment in subjects with genu valgum and genu varum deformities and healthy subjects  in order to understand the lower extremity alignment changes in this group.  Methods: This was a causal-comparative study. The sample comprised 120 m...

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...
