Lameness is due to joint instability, or joint laxity. The instability or laxity is usually due to trauma of some sort (excessive jumping and/or landing, fast stops and turns etc.). The laxity produces joint weakness, inflammation, and pain. The procedure works whether or not the joint has arthritis (degenerative joint disease) or not. This is because the calcification does not produce the pain to the degree that capsular inflammation does. It is for this reason that it is beneficial to many of our older canine patients.
The solution creates a situation of low grade inflammation, not enough to cause increased soreness, but enough to stimulate the production of mesodermal cells. These cells increase the strength and thickness of the soft tissue components. Therefore, this type of treatment is a type of stem cell therapy. The increased strength and thickness results in joint stability. As joint stability is achieved, the pain diminishes.
