Instability-Associated Changes in Contact Stress and Contact Stress Rates in Human Cadaveric Ankles

摘要

BackgroundIntra-articular fractures can result in articular surface incongruity and joint instability, both of which can lead to post-traumatic osteoarthritis. The purpose of this study was to quantify changes in contact stresses and contact stress rates in incongruous human cadaveric ankles that were either stable or unstable. It was hypothesized that joint instability, superimposed on articular incongruity, would cause significant increases in contact stresses and contact stress rates.
