The objective was to determine the extent to which the external peak knee adduction moment (KAM) and cumulative knee adductor load explained variation in medial cartilage morphology of the tibia and femur in knee osteoarthritis (OA). Sixty-two adults with clinical knee OA participated (61.5 ± 6.2 years). To determine KAM, inverse dynamics was applied to motion and force data of walking. Cumulat...

Knee osteoarthritis (OA) is the most common form of arthritis, and affects approximately one-third of the elderly population. The medial tibiofemoral compartment is most commonly involved. This is due, in part, to the ground reaction force vector passing medial to the knee joint center during gait. This distance increases with genu varus malalignment, resulting in an increased external adductio...

Lower limb dynamic alignment represents the limb position during functional loading conditions and obtains valuable information throughout the gait cycle rather than a single instant in time. This study aims to determine whether dynamic alignment is altered in medial knee osteoarthritis (OA) and how dynamic alignment is related to knee adduction moment (KAM). Community-dwelling women (n=17) wit...

OBJECTIVE Demonstrate the presence and magnitude of biomechanical variables during gait in patients with medial knee osteoarthritis (OA) and the relationship with the knee loading. METHODS Gait of 21 subjects diagnosed with medial knee OA was evaluated and compared to the control group. RESULTS THE GROUP WITH OA SHOWED: Lower gait speed (0.8 ± 0.1 vs. 1.1 ± 0.1m/s), higher peak early (2.6 ±...

Recently, the increase of transfemoral amputees from industrial disasters, traffic accidents, vascular diseases and aging is emerging as a social issue. For transfemoral amputees, it is very important to recover their lost functions. Myoplasty, which is one of above-knee amputation methods that sutures muscles on the femoral stump, is used more commonly than other operation methods because it i...
