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...

objectives: the aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how total knee replacement (tkr) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. methods: two-dimensional kinematic gait pattern of 10 participants were collected before and after the tkr surgery, using a ...

Knee joint pain is one of the most common complaints related to the skeletal system encountered by paediatricians. Knee joint pain generally occurs as the result of hypermobility and growing pains, though disorders manifesting as arthritis/arthralgia and orthopaedic problems should be considered in the differential diagnosis. A thorough and careful physical examination and laboratory and radiol...

Individuals with unilateral transtibial amputations have greater prevalence of osteoarthritis in the intact knee joint relative to the residual leg and non-amputees, but the cause of this greater prevalence is unclear. The purpose of this study was to compare knee joint contact forces and the muscles contributing to these forces between amputees and non-amputees during walking using forward dyn...

Inverse dynamics analysis is commonly used to estimate the net loads at a joint during human motion. Most lower-limb models of movement represent the knee as a simple hinge joint when calculating muscle forces. This approach is limited because it neglects the contributions from tibiofemoral joint contact forces and may therefore lead to errors in estimated muscle forces. The aim of this study w...

[Purpose] For preventing the patellofemoral pain syndrome, this study aims to suggest a proper squat method, which presents selective muscle activity of Vastus Medialis Oblique and muscle activity ratios of Vastus Medialis Oblique/Vastus Lateralis by applying squat that is a representative weight bearing exercise method in various ways depending on the surface conditions and knee bending angles...

Knee osteoarthritis is associated with structural changes in the joint. Despite its many drawbacks, radiography is the current standard for evaluating joint structure in trials of potential disease-modifying osteoarthritis drugs. MRI is a non-invasive alternative that provides comprehensive imaging of the whole joint. Frequently used MRI measurements in knee osteoarthritis are cartilage volume ...

OBJECTIVE To investigate gender differences in three-dimensional hip and knee joint mechanics in collegiate athletes during a randomly cued cutting maneuver. DESIGN Three-dimensional kinematics and kinetics were collected on 24 collegiate soccer players (12 females and 12 males) while each performed the cutting maneuver. In order to create a randomly cued condition, subjects were signaled by ...

INTRODUCTION The Anterior Cruciate Ligament (ACL) is the ligament that connects the anterior portion of the tibia to the posterior section of the femur, stabilizing the joint and limiting anterior translation of the tibia. Certain activities involving motions that suddenly strain the knee such as cutting or jumping in basketball or football, can result in an ACL tear. ACL reconstructions (ACLR)...
