Evidence-Based Selection of Non-Microprocessor Knees
Episode 60
Wednesday, 23 September, 2026
In this episode, Dr. Steve Gard, editor-in-chief of the Journal of Prosthetics and Orthotics, welcomes Andreas Kannenberg, MD, PhD, to discuss his JPO article, “Systematic Review of the Clinical and Biomechanical Evidence for Non-Microprocessor Control Knee Mechanisms and Practical Recommendations for Knee Selection.” Dr. Kannenberg explains why non-microprocessor knees remain an important part of prosthetic care, particularly when cost, insurance coverage, and access limit the use of microprocessor technology. He shares findings from a review of 28 studies involving more than 1,000 participants, examining the evidence behind different knee mechanisms and the tradeoffs between stability, function, and the strength required of the user. The conversation explores locked, friction-brake, four-bar, multi-axial, and hydraulic knee mechanisms, how their performance can vary across different terrains, and why some commonly held assumptions about polycentric knees may deserve a closer look. Dr. Kannenberg also discusses gaps in the existing research and the need for larger, higher-quality studies, particularly in countries where non-microprocessor knees remain the standard of care. Show notes JPO article: Systematic Review of the Clinical and Biomechanical Evidence for Non-Microprocessor Control Knee Mechanisms and Practical Recommendations for Knee Selection O&P Research Insights is produced by Association Briefings.
