Pre-pandemic, we investigated the effect of maximal shoes on walking gait, specifically comparing biomechanical risk factors for developing knee osteoarthritis (OA) between shoes. We also performed a pilot study comparing walking biomechanics between traditional knee arthroplasty (TKA) and robot-assisted TKA using the Mako procedure. We are now recruiting participants who have knee OA to participate in a similar study to our previous investigation, comparing walking biomechanics between maximal, traditional, and minimal footwear. If you have knee OA and are interested in participating, please contact Dr. JJ Hannigan.
