Some benefits of stem cell injections for knee cartilage repair are the simplicity of the procedure, no hospitalization requirement following treatment, pain relief, and improvement in the quality of the cartilage. Other benefits include meniscus regeneration, and the relief of stiffness and disability in the patient, says Caring Medical.
Tendons, muscles and ligaments of the knee surround the articular ligament, explains Caring Medical. Weakening of the ligaments diminishes stability and flexing at the knee joint while advancing wear and tear on the knee at an abnormal rate. In an effort to stabilize the knee, the joint swells and the bone overgrows in some cases, resulting in osteoarthritis. This swelling leads to more pain.
Limited treatment options for tissue restoration, as well as prevention of osteoarthritic and degenerative changes in the knees, present a need for stem cell therapy and other treatment options, states Caring Medical. The procedure requires drawing stem cells from the patient and then injecting them into the knee. Tissue engineering research, such as stem cell therapy, restores function of the damaged knee. Meniscus regeneration results from several injections of stem cells.
Part of the healing process for stem cell therapy of the knee is promoting the production of hyaluronic acid, which lubricates and cushions the knee, reports Caring Medical. Studies show that a single injection of stem cells into the knee effectively stimulates regeneration of the meniscus and relieves pain. Repeated injections protect the medial femoral articular cartilage from further injury.
