Prolotherapy, also known as nonsurgical ligament reconstruction, is a medical treatment for chronic pain.
“Prolo” is short for proliferation, because the treatment causes the proliferation (growth, formation) of new connective tissue in areas where it has become weak. Prolotherapy is primarily used to treat joint pain, and has been clinically shown to increase joint ligament strength by 30-40% in people.
Clinical results using prolotherapy in dogs and cats appear to indicate the same response. Many elite human athletes use prolotherapy to strengthen their weak ligamentous tissues to prevent against future tears and injury.
