Abstract

Sound speed of a capsule in a rat knee contracture model was measured by scanning acoustic microscopy. There was no statistical significant difference in the anterior capsule compared with the control group. However, the sound speed of the posterior capsule was significantly greater compared with the control group after prolonged immobilization.
