This study examined the biomechanical effects of a tri-compartment offloader brace (TCO) in patients with multi-compartment knee OA while they performed actions of daily living. Results showed that Levitation can significantly reduce quadriceps muscle effort and internal knee extension moments.
By using a biomechanical model of the knee, this study demonstrated a tri-compartment offloader brace (TCO) can reduce a number of contact and ligament forces across the knee during a deep knee bend. The results replicate and extend the findings of Budarick et al. 2020, which demonstrated that a TCO can reduce knee joint loading.
This biomechanical study outlines the unique design and function of the Levitation knee brace and demonstrates that Levitation can reduce patellofemoral and tibiofemoral joint contact forces to a level that would be achieved by losing 45 lbs of body weight.
An exploratory study of brace effectiveness was completed in a group of adults (n=40) with varied patterns of activity-related knee pain characteristic of patellofemoral, tibiofemoral, or multi-compartment knee OA.
