Regenerative Repair of Damaged Meniscus with Autologous Adipose Tissue-Derived Stem Cells

This article analyzes adipose-derived mesenchymal stem cells (A-MSCs) in a meniscus tear of the knee. The patient underwent liposuction and the A-MSC was combined with Platelet-rich plasma (PRP) as an injection into the meniscus under ultrasound. Then PRP and hyaluronic acid booster injections were performed, then another injection by PRP and low dose dexamethasone, followed by a final booster injection of PRP. The patient had significant reduction of pain, inflammation, improved functional abilities, and a 3-month post-injection MRI showed a healed meniscus!

The Takeaway: Meniscus tears are commonly treated by surgical excision, but this type of surgery has its risks. This patient was faced with the decision of either having surgery or trying this new type of regenerative procedure. Research has shown that meniscectomies predispose a patient to early-onset osteoarthritis because the meniscus is a protective structure, and removing it leaves the knee joint more vulnerable to injury or wear and tear. If there is a way to heal tissues using a sophisticated injection of your own stem cells, then this would certainly be preferred since it could prevent the potential complications and later problems that can result from invasive surgeries. Luckily, this type of treatment helps more than just knees. If you find yourself faced with the possibility of surgery, come in for an evaluation with Dr. Silva to see if you have a better option.
