Will stem cell injections fix my knee?

Will a stem cell injection fix my knee? The answer is, "It depends". Stem cell injections are not a panacea that will fix every knee injury regardless of type and severity. For example, a patient might have loose bodies like cartilage or bone fragments inside their knee joint, which can cause painful inflammation, degeneration of the joint and “catching” of the knee. These loose bodies must be surgically removed. Stem cell injections are not going to make them go away. However, stem cells and other biologics like AlphaGEMS amniotic tissue product can be used to promote faster healing after loose bodies are removed with minimally invasive surgery. read more »
