A patient-specific lower extremity biomechanical analysis of a knee orthotic during a deep squat movement.

Although knee orthotics have become the preferred treatment method for rehabilitation and injury prevention, their biomechanical influence has not yet been quantified. A new type of knee joint orthosis (KJO) using a non-linear spring-loaded (NLSL) component was recently introduced to help prevent the growing number of knee injuries and aid during rehabilitation. The purpose of this case study is to quantify the lower extremity biomechanical effects and evaluate functional benefits of a new KJO as a precision treatment option.
