Comparing the Efficacy of Lyophilized Self Growth Factor Versus PRP Injection for Knee OA

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Knee Osteoarthritis, PRP Injection

In brief

Knee osteoarthritis(OA) is a common degenerative joint disease that often leads to knee pain, stiffness, and a decline in quality of life among middle-aged and elderly individuals. Platelet-rich plasma (PRP) is a regenerative treatment method that involves drawing a small amount of the patient's own blood and using centrifugation process to produce PRP. PRP, which is rich in growth factors and anti-inflammatory cytokines, facilitate the repair of damaged tissues and has been used in treating knee OA. Self-repair factor (SRF), an advanced form of PRP, is created using multi-step centrifugation and proprietary processes to increase platelet concentration. This enhancement may offer superior repair efficacy and faster recovery compared to traditional PRP. To explore this potential, we designed a randomized, double-blind, clinical trial to compare the effectiveness of SRF and PRP in treating degenerative knee osteoarthritis.
