What is a CPM and why is it used?

Continuous Passive Motion is a post-operative therapy that moves a joint passively through a prescribed range of motion for a prescribed period of time. While passive motion is a common therapy modality, continuous passive motion requires a device to attain the continuous motion requirements needed to gain the benefits of CPM.

Some of the proven benefits of CPM are:

• Prevention of Immobilization Disease
  • Adhesion Formation
  • Joint Contractures
  • Degeneration of Articular Cartilage
  • Degeneration of Periarticular Cartilage

• Improved Joint Nutrition
  • Enhanced Delivery of oxygen and nutrients
  • Improved circulation of synovial fluid to joint surfaces

• Remodeling of Joint Surfaces
  • Wolfs Law – Healing tissue will be laid down in a pattern dictated by the stresses imposed upon it, collagen fiber is less randomized and more structured
  • Stimulation of stem cells to produce cartilage cells

• Faster ROM gain

• Faster resorption / reduction of swelling conditions

• Decreased need for pain medication

• Greater compliance to active & strengthening rehabilitation programs
