Local Tensile Stress in the Development of Posttraumatic Osteoarthritis

Figure 3

Finite element analysis. (a) The distribution of tensile stress around the 45° crack and the peak was 0.59 MPa. (b) The distribution of tensile stress around the 90° crack and no tensile stress existed. (c) The maximal tensile stress variation with the crack angle.
