Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Western Ontario and McMaster Universities Osteoarthritis Index

    The structure and function of the knee joint are assessed from three main aspects: pain, stiffness, and joint function, with a total of 24 items. The pain section consists of 5 items (24 points in total), the stiffness section has 2 items (8 points in total), and the joint function section includes 17 items (68 points in total). A lower score indicates more severe pain, stiffness, and a higher degree of disability.

    Pre-treatment, 1st month, 2nd month, 3rd month, 6th month

Secondary Outcomes (3)

  • Visual Analogue Scale

    Pre-treatment, 1st month, 2nd month, 3rd month, 6th month

  • The intermittent and constant pain score , ICOAP

    Pre-treatment, 1st month, 2nd month, 3rd month, 6th month

  • Timed Up and Go test

    Pre-treatment, 1st month, 2nd month, 3rd month, 6th month.
