Are increased knee joint loads during walking present in subjects with knee osteoarthritis?
Load reducing mechanisms, such as a decreased midstance knee flexion angle, identified by others in subjects with endstage knee OA or reduced external flexion or extension moments were not present in this group of subjects with knee OA who were being managed by conservative treatment. The finding of a significantly greater than normal external knee adduction moment in the knee OA group lends support to the hypothesis that an increased knee adduction moment during gait is associated with knee OA.
Surgical intervention for aortic arch disease in octogenarians can yield satisfactory early clinical outcomes and acceptable mid-term survival with adequate daily activity. This study indicates that among octogenarians, age alone should not disqualify a patient from receiving an aortic arch intervention.
