Watch a Platelet-rich stroma procedure performed for a case of knee osteoarthritis. The patient has advanced OA changes as seen on 3T MRI and cartigram.
What is Platelet-rich stroma?
Platelet-rich stroma (PRS) is a combination of platelet-rich plasma (PRP) and stromal vascular fraction (SVF). PRS includes stromal cells in their matrix with stimulating factors and plays an important role in reducing articular inflammation and signalling cartilage repair in osteoarthritis. It contains SVF obtained from fat. Fat is a better source of multipotential signaling cells than bone marrow. Tissue SVF is combined with Platele-rich plasma (PRP) before intra-articular injection. Fat is harvested by mini liposuction from the thigh, buttocks, or abdominal fat through tiny incisions. The incisions heal naturally without sutures.
PRP is prepared from venous blood. It concentrates platelets several fold times. Platelets contain growth factors which assist in tissue repair.
It is injected into the knee under ultrasound guidance. Ultrasound-guided knee injections are more accurate than blind injections. Keyhole surgery (arthroscopy) or spinal anesthesia is not involved in my procedure. Platelet-rich stroma is a revolutionary procedure to treat osteoarthritis of the knee. Platelet-rich stroma relieves the pain of osteoarthritis immediately and its effect can last for a few years. Over a period of time limited cartilage repair is seen. See the technique of ultrasound-guided PRS injection here. Platelet-rich stroma is preferred by many patients nowadays as an alternative to knee replacement
How is it done?
The procedure is performed under local anaaesthesia. It is injected under ultrasound guidance. Ultrasound-guided knee injections are more accurate than blind injections. Keyhole surgery (arthroscopy) or spinal anesthesia is not involved in my procedure.
No spinal anesthesia is required. Keyhole surgery is not used. Both knees can be done in one sitting. The patient walks into the OR and walks out after the procedure. They experience immediate pain relief. PRS, SVFhttps://www.orthobiologicsurgeryindia.com and PRP are commonly performed biologic injections in my practice. I also perform knee replacements for advanced cases of knee arthritis. ACL reconstruction, and meniscal repair, are the common arthroscopic procedures.
