Stem cell injections are a promising area of medicine and research. Stem cells have the unique capability to transform into any cell the body needs, making them capable of replacing the specialty cells of the body that would otherwise be irreplaceable (such as muscle cells and cartilage). The ability to inject stem cells into these problematic areas can help to repair injuries that would otherwise potentially have become permanent.Theoretically, a stem cell injection will be able to treat any condition of the body caused by damaged or missing tissue, with the stem cells simply becoming the cells the body needs. The majority of stem cell treatments are in the early stages of clinical testing.There are several small studies available that have shown the benefits of stem cell procedures for musculoskeletal indications. This includes joint arthritis, tendonitis, ligament injury, and all types of sports injuries.Some patients have been able to delay or avoid the need for surgery with these regenerative procedures.
