Comparison of peak knee adduction moment and knee adduction moment impulse in distinguishing between severities of knee osteoarthritis.

Background: The peak knee adduction moment is a valid proxy for medial knee joint loading. However as it only measures load at one instance of stance, knee adduction moment impulse, a measure that takes into account both the magnitude and duration of the stance phase, may provide more comprehensive information. This study directly compared the abilities of peak knee adduction moment and knee adduction moment impulse to distinguish between knee osteoarthritis severities.

Lateral wedge insoles for medial knee osteoarthritis: effects on lower limb frontal plane biomechanics.

Background: Lateral wedges reduce the peak knee adduction moment and are advocated for knee osteoarthritis. However some patients demonstrate adverse biomechanical effects with treatment. Clinical management is hampered by lack of knowledge about their mechanism of effect.

Laterally wedged insoles in knee osteoarthritis: do biomechanical effects decline after one month of wear?

Objective: This study aimed to determine whether the effect of laterally wedged insoles on the adduction moment in knee osteoarthritis (OA) declined after one month of wear, and whether higher reported use of insoles was associated with a reduced effect on the adduction moment at one month.

Methods: Twenty people with medial compartment OA underwent gait analysis in their own shoes wearing i) no insoles and; ii) insoles wedged laterally 5 degrees in random order. Testing occurred at baseline and after one month of use of the insoles.

Colorectal surgical specimen lymph node harvest: improvement of lymph node yield with a pathology assistant.

Introduction: Adequate lymph node harvest from colorectal cancer specimens has become a standard of care, influencing both staging and survival. To improve lymph node harvests at our hospital, a pathology assistant was trained to meticulously harvest lymph nodes from colorectal cancer specimens. An analysis of trends in lymph node harvests over time is presented.
