Abstract

Background: Knee osteoarthritis (KOA) is a common degenerative joint disease that primarily affects the elderly individuals. Traditional treatments include medications and physical therapy, but recent attention has turned to platelet-rich plasma (PRP) and hyaluronic acid (HA) injection therapies. Objective: This meta-analysis aimed to evaluate the efficacy and safety of PRP combined with HA versus PRP alone in the treatment of KOA. Methods: We conducted a comprehensive literature search of the PubMed, Embase, and Cochrane Library databases, which included covering publications from their inception to July 2024. Studies comparing PRP+HA with PRP alone were selected. Data on visual analog scale (VAS) scores, WOMAC total scores, Lequesne scores, and adverse events were extracted. Statistical analysis was performed via Review Manager 5.3.5. Result: This meta-analysis included 16 studies involving a total of 1,384 patients. The VAS score comparison indicated that, in the long term, PRP combined with HA was more effective in reducing knee pain than PRP alone was (SMD: -0.30, 95% CI: -0.53 to -0.06, P = 0.01). The combined PRP and HA treatment achieved better results in terms of the WOMAC total score (MD = -6.58, 95% CI: -10.65 to -2.52, P
