Instability-Associated Changes in Contact Stress and Contact Stress Rates Near a Step-Off Incongruity [PDF]
The Journal of Bone & Joint Surgery, 2008 Intra-articular fractures can result in articular surface incongruity and joint instability, both of which can lead to posttraumatic 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.
