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.

Detailed description

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. Treatment options include weight loss, anti-inflammatory and pain-relieving medications, physical rehabilitation, and intra-articular injections of corticosteroids or hyaluronic acid. However, these methods often have limited efficacy or may cause side effects. 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. However, there is still lack of strong evidence of the therapeutic effects of PRP injection in knee OA. Therefore, there is a need to investigate novel therapies for 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. Patients with mild to moderate knee osteoarthritis who have experienced symptoms for more than three months. 30 participants will be recruited and randomly divided into three groups: the SRF group, the PRP group, and a control group. Each participant will receive knee intra-articular injections as part of a three-month treatment regimen, with one injection per month for a total of three injections. Patients will be evaluated before the trial, and at one, two, three, and six months after the injections. Clinical outcomes will be assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Intermittent and Constant Osteoarthritis Pain (ICOAP) scale, the sit-to-stand test, and the Visual Analog Scale (VAS) for pain. The study aims to confirm the clinical efficacy of SRF in treating degenerative knee osteoarthritis.

Design outcomes

Primary

MeasureTime frameDescription
Western Ontario and McMaster Universities Osteoarthritis IndexPre-treatment, 1st month, 2nd month, 3rd month, 6th monthThe 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.

Secondary

MeasureTime frameDescription
Visual Analogue ScalePre-treatment, 1st month, 2nd month, 3rd month, 6th monthChange from baseline of pain on 1st month, 2nd month, 3rd month, 6th month after injection. Pain severity was evaluated using visual analog scale (VAS). Pain score scale ranged from 0 to 10, with 10 indicating the most severe pain
The intermittent and constant pain score , ICOAPPre-treatment, 1st month, 2nd month, 3rd month, 6th monthThe content is divided into two subcategories: continuous pain (5 items) and intermittent pain (6 items), with a total of 11 items. Each item is scored from 0, representing no pain, to 4, representing extreme pain. A higher score indicates more severe pain. The Chinese version has reliable validity and reliability.
Timed Up and Go testPre-treatment, 1st month, 2nd month, 3rd month, 6th month.Align the chair legs with the starting baseline and place a cone 3 meters ahead. The participant sits in the chair with their feet naturally bent, stands up comfortably, walks forward for 3 meters, turns around, and walks back to sit down. The time taken to complete the task is recorded. This test has good validity and reliability for assessing the mobility of patients with degenerative knee osteoarthritis.
