A motorized device known as a continuous passive motion (CPM) machine passively moves a joint through a predetermined range of motion. After surgery, these devices may be used to ease joint stiffness and increase range of motion.
After surgery, regaining normal joint mobility can be quite difficult. A joint's stiffness may be a problem that hinders progress and hurts. Due to this, some surgeons utilize CPM to enhance range of motion and attempt to avoid the formation of scar tissue. CPM is most frequently indicated following knee replacement or knee cartilage repair surgery, though it may be advised after surgeries like ACL reconstruction or frozen shoulder surgery.
