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. Recently we completed a study comparing walking biomechanics between maximal, traditional, and minimal footwear in individuals with knee OA, and are in the process of publishing these findings.
