A New Paradigm in the Management of Knee Osteoarthritis and Arthroplasty with Dynamic Patient-source Outcome Measures: Comprehensive Clinical Review of the Knee Kinesiography Exam with the KneeKG® System

Abstract

While knee disorders, and more specifically knee osteoarthritis, account for a significant portion of the orthopedic visits to health care providers, there are still clinical gaps that need to be addressed to achieve effective management of this disease. The absence of functional tools to objectively assess knee function in motion and weight-bearing conditions poses a challenge for clinicians to hindering their ability to design individualized conservative and surgical treatment plans aimed at achieving better patient outcomes. The Knee Kinesiography exam with the KneeKG® system provides accurate, reliable, three-dimensional, and real-time information about dynamic knee malalignment and joint dysfunction during weight-bearing activities through the assessment of kinematic biomechanical markers. This work presents a comprehensive clinical review of the materials related to this exam which have been published since its validation in 2012. The aim is to summarize literature evidence on how the Knee Kinesiography exam may enhance both non-surgical and surgical management of knee osteoarthritis and arthroplasty. The access to objective patient-source outcome measures from this exam, directly associated with both patient-reported outcomes and osteoarthritis onset and progression before and after total knee arthroplasty, can allow clinicians to identify mechanisms behind knee pain, dysfunction, and dissatisfaction. In the era of orthopedic value-based care, such patient-source data may help clinicians better understand the condition of the knee and thus assist them in their decision-making to establish the best personalized care plan possible throughout the continuum of care, from diagnosis to post-surgery management.
