PRP & PRF Regenerative Injections

Image-guided platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) injections at StemWave Pro LA, performed under ultrasound or fluoroscopy guidance by Dr. Padra Nourparvar, DO, within Cedars Sinai Medical Office Towers. PRP and PRF concentrate the patient's own growth factors from a blood draw to accelerate tissue repair in tendons, joints, ligaments, and soft tissue. The clinic cites a 70–85% patient improvement rate. Recovery typically allows return to light activity within 24–48 hours.

Platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) therapy at StemWave Pro LA represents the core regenerative offering of the Stem Cell & PRP Institute of L.A., performed by Dr. Padra Nourparvar, a board-certified osteopathic physician with training at UCLA, UC Irvine, NYU, CHLA, and Mount Sinai. PRP is prepared by drawing a small volume of the patient's blood and processing it in a centrifuge to concentrate platelets — blood cells that contain an abundance of growth factors including platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor-beta (TGF-β), and insulin-like growth factor (IGF-1). These growth factors play central roles in the inflammatory cascade, angiogenesis, and extracellular matrix remodeling that underpin tissue repair. When injected at the site of an injury or degenerative condition, the concentrated platelet payload signals nearby fibroblasts, tenocytes, chondrocytes, and stem cells to initiate and accelerate local repair processes. PRF (platelet-rich fibrin) is a second-generation preparation that uses no anticoagulant, allowing the platelets and fibrin to form a gel matrix that releases growth factors more slowly and sustainably at the injection site. At StemWave Pro LA, injections are delivered under ultrasound or fluoroscopy image guidance to ensure precise placement within the target tissue — a clinical standard that distinguishes the procedure from blind injection techniques and improves accuracy in challenging anatomical locations such as the hip, shoulder rotator cuff, knee meniscus, and spine. Common indications include osteoarthritic joints, tendinopathy, ligament sprains, plantar fasciitis, and partial rotator cuff tears. The clinic reports a 70–85% patient improvement rate across its regenerative injection caseload. Most patients return to light activity within 24–48 hours post-procedure. A course of injections may be recommended depending on the severity and chronicity of the condition. The clinic is located at the prestigious Cedars Sinai Medical Office Towers on West 3rd Street, serving patients from West Hollywood, Beverly Hills, Century City, and the greater Los Angeles area.
