Abstract Objective To test the hypothesis that a greater peak internal hip abduction moment is associated with reduced likelihood of ipsilateral medial tibiofemoral osteoarthritis (OA) progression. Methods Fifty‐seven persons knee OA (by definite osteophyte presence and symptoms) were evaluated. Baseline assessments included kinematic kinetic gait parameters, obtained an optoelectronic camera system force platform, inverse dynamics used to calculate 3‐dimensional moments at joints; pain,...

To determine whether the presence of varus thrust at baseline increases risk progression medial tibiofemoral osteoarthritis (OA), knees with have a greater adduction moment, has any additional impact on top static varus, and is associated poor physical function outcome.Two hundred thirty-seven patients knee OA (definite osteophytes symptoms) underwent gait observation to assess full-limb radiography alignment. Sixty-four these 237 also quantitative analysis maximum moment. Two thirty (97%)...

<h3>Background:</h3> A greater knee adduction moment increases risk of medial tibiofemoral osteoarthritis (OA) progression. Greater toe-out during gait shifts the ground reaction force vector closer to centre knee, reducing moment. The present study was designed test whether is associated with lower likelihood OA <h3>Methods:</h3> Baseline assessments included: kinematic/kinetic parameters using an optoelectronic camera system, platform and inverse dynamics calculate three-dimensional...

Varus thrust observed during gait has been shown to be associated with a 4-fold increase in the risk of medial knee osteoarthritis (OA) progression. Valgus is believed less common than varus thrust; prevalence each uncertain. Racial differences factors may help explain variations natural history OA. We undertook this study determine frequency and valgus African Americans Caucasians identify presence.The Osteoarthritis Initiative cohort includes men women who have OA or are at increased...

To determine if varus thrust, a bowing out of the knee during gait (i.e., first appearance or worsening alignment stance), is associated with incident and progressive osteoarthritis (OA), we undertook an Osteoarthritis Initiative ancillary study. We further considered hypothesized associations adjusted for static alignment, anticipating some attenuation.Gait was observed presence thrust by 1 2-3 examiners per study site at 4 sites. In eligible knees, OA defined as subsequent...

Abstract Objective To examine the correlation between hip‐knee‐ankle and femur‐tibia radiograph angles, calculate offset of angle with respect to angle, sensitivity specificity area under receiver operating characteristic (ROC) curve relationship malalignment by each approach osteoarthritis (OA) tissue pathology in mechanically stressed compartment using magnetic resonance imaging (MRI). Methods Individuals knee OA underwent full‐limb radiographs MRI. Linear regression was used determine if...

Varus-valgus alignment has been linked to subsequent progression of osteoarthritis (OA) within the mechanically stressed (medial for varus, lateral valgus) tibiofemoral compartment. Cartilage data from off-loaded compartment are sparse. The purpose this study was examine our hypotheses that neutral and valgus (versus varus) knees each have reduced odds cartilage loss in medial subregions varus subregions.Patients with knee OA underwent magnetic resonance imaging at baseline 2 years. mean...

Abstract Objective To evaluate whether low knee confidence at baseline is associated with poor baseline‐to‐3‐year physical function outcome in the Osteoarthritis Initiative. Methods Knee was assessed using an item from Injury and Outcome Score instrument. Physical self‐report measures (Western Ontario McMaster Universities Index [WOMAC] score Short Form 12 component scale) performance‐based (20‐meter walk chair stand test). Poor defined as moving into a worse group or remaining 2 worst...

Objective Few strategies to improve pain outcome in knee osteoarthritis (OA) exist part because how best evaluate over the long term is unclear. Our objectives were determine frequency of a good experience based on previously formulated OA stages and test hypothesis that less depression catastrophizing greater self‐efficacy social support are each associated with likelihood outcome. Methods Study participants, all OA, reported stage at baseline 2 years. Baseline assessments utilized...

Objective Manifestations of instability in knee osteoarthritis (OA) include low overall confidence, confidence that the knees will not buckle, buckling, and excessive motion during gait. Confidence buckling may particularly influence activity choices, contributing to events leading disability. Buckling is more likely affect advanced than basic functional tasks. In this prospective longitudinal study, we tested hypothesis frontal plane gait are associated with 2‐year function outcomes persons...

Persons with knee symptoms recognize the health benefits of engaging in physical activity, but uncertainty persists about whether regular strenuous activity or exercise can accelerate tissue damage. A sedentary lifestyle inactivity underloading may also be associated deleterious joint health.To establish long-term participation and extensive sitting behavior are each increased risk developing radiographic osteoarthritis (KOA) individuals at high for disease.This cohort study analyzed data...

Abstract Objective To test the hypotheses that 1) osteoarthritic (OA) knees at more advanced stages have less anteroposterior (AP) laxity compared with OA milder stages, 2) AP decreases over time, and 3) absence of a decrease in is associated greater progression medial tibiofemoral OA. Methods The study group comprised 230 patients knee (75% women, mean age 64 years, body mass index [BMI] 30 kg/m 2 ).
