When stem cells are injected into an arthritic joint or injured tendon, they attach to the areas of damaged tissue and release the right combination of growth factors and proteins to stimulate healing and new growth of cartilage, tendon and other injured tissues.
Multiple clinical research papers conclude that adipose (fat) derived stem cell treatment significantly improves pain and function in addition to increasing cartilage volume and quality.
According to published research, stem cell therapy for knee arthritis results in 58-68% improvement in pain and 67-83% improvement in function one to two years after treatment. Most of this improvement occurs in the first three to six months. Tendon and other soft tissue injuries can respond even better.
