Purpose: The purpose of this study is to examine the differences of kinetic and kinematic variables in middle-aged women with genu varum and normal knee angle during walking and running. Methods: Eight middle-aged women with genu varum (age: 45.12 ±12.74 y, height: 160.62 ± 5.26 cm, weight: 71.75 ± 16.38 kg, right tibiofemoral angle: -4 ± 3.9, left tibiofemoral angle: -5.1 ± 4.6) and 7 wi...

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 ...

Stiff-knee gait is a movement abnormality in which knee flexion during swing phase is significantly diminished. This study investigates the relationships between knee flexion velocity at toe-off, joint moments during swing phase and double support, and improvements in stiff-knee gait following rectus femoris transfer surgery in subjects with cerebral palsy. Forty subjects who underwent a rectus...

BACKGROUND Studies have suggested that the symptoms of knee osteoarthritis (OA) are rather weakly associated with radiographic findings and vice versa. Our objectives were to identify estimates of the prevalence of radiographic knee OA in adults with knee pain and of knee pain in adults with radiographic knee OA, and determine if the definitions of x ray osteoarthritis and symptoms, and variati...

Simulation results suggest that the primary mechanism for improvement in knee flexion after surgery is reduction of the muscle’s knee extension moment, rather than conversion to a knee flexion moment. Scarred transfer simulations resulted in an average peak knee flexion improvement (14° ± 5°) comparable to the average increase in knee flexion range of motion (13° ± 11°) in the subjects’ postope...

Total knee arthroplasty (TKA) is one of the most successful procedures in modern orthopedic surgery, providing high patient satisfaction rate. As a result, the number of patients undergoing TKA is increasing in number every year and more patients would be inclined to have the operation in near future . The demand for TKA is expected to grow 673% between 2005 and 2030. Knee surgeons are using mo...

Experiments were carried out on anesthetized adult New Zealand rabbits. Acute joint inflammation was achieved by intra-articular injection of 2% carrageenan. Radiolabelled microspheres were used to measure the effect of acute inflammation on blood flow in the knee joint and establish whether neural influences on blood vessel caliber were affected. Surgical exposure of the posterior joint "capsu...

OBJECTIVE To test whether knee stabilization therapy, prior to strength/functional training, may have added value in reducing activity limitations only in patients with knee osteoarthritis who have knee instability and (i) low upper leg muscle strength, (ii) impaired knee proprioception, (iii) high knee laxity, or (iv) frequent episodes of knee instability. DESIGN Subgroup analyses in a rando...
