Osteoarthritis develops in a joint when changes occur in the cartilage; the soft tissue that protects the surface of a bone and allows the joint to move freely. These changes affect how the joint works and maybe due to damage that occurred to the joint many years before any symptoms appear. Bony outgrowths form at the outer edges of the joint, making it look knobbly and thickening of the membrane and capsule enclosing the joint make it stiff, painful to move and sometimes inflamed, which causes a lot of pain and changes the shape of the joint.

Shockwave therapy offers an exciting addition to the treatment options for Osteoarthritis. The role of this therapy is in slowing the progression of osteoarthritis and it can actually alter the process of cartilage degradation. The shockwaves stimulates certain components within the body, so the body is able to heal.
