Evaluation of the Effects of Hyaluronic Acid on Knee Joint Osteoarthritis

Abstract: Background and Purpose: Knee osteoarthritis (OA) is a degenerative joint disease that commonly affects middle-aged and elderly individuals. It results in cartilage degradation, pain, inflammation, and limited mobility. This study explores the therapeutic effects of hyaluronic acid (HA) on the symptoms of knee OA, focusing on its ability to alleviate pain, improve joint function, and enhance the quality of life for patients. Methodology: This research is a library-based review, analyzing scientific literature and clinical studies on the use of intra-articular HA injections in treating knee OA. The review synthesizes data from various meta-analyses, clinical trials, and systematic reviews to evaluate the efficacy and safety of HA injections. Key Findings: The findings suggest that HA injections can effectively reduce pain, improve joint mobility, and enhance the quality of life for patients suffering from knee OA. These benefits are typically observed within weeks to months after the injections. However, there are limitations, including high treatment costs and the need for repeated injections, which may affect patient adherence. Conclusion: Intra-articular hyaluronic acid injections are a valuable non-surgical treatment option for knee OA. Despite certain limitations, HA injections provide significant symptomatic relief with minimal side effects, making them an effective supplementary therapy in the management of knee OA.
