Proliferative therapy works by helping the body repair damaged connective tissue in the problem area. Connective tissue includes the cartilage, ligaments, and tendons that cushion and/or stabilize and support our joints. Cartilage can be torn by sudden improper movements or just worn away from overuse and improper alignment. Accidents, sports injuries, or just plain overuse can cause ligaments and tendons to tear or lose elasticity and become like frayed ropes or lax rubber bands. Full or complete tears must be repaired surgically. However, much more common are micro-tears or general loss of tensile strength in these tissues. Weakened ligaments and tendons put a severe strain on the affected areas and joints causing pain, dysfunction, arthritis, damage to cartilage, and many other chronic problems. In addition to chronic pain, some other key symptoms that ligament or tendon damage is contributing to your problem.
