About

This clinical trial study is conducted in Vietnam to assess the efficacy and tolerability of Proteoglycan F in the treatment of primary knee osteoarthritis. 72 outpatients (40-80 years old) were diagnosed with primary knee osteoarthritis and met the American College of Rheumatology 1991 criteria. Patients have to be symptomatic for ≥ 3 months before enrollment and have a radiologic grade II and III measured by the Kellgren-Lawrence criteria. The study was designed as a Prospective, Randomized, Double-blind Controlled trial. Each patient will be follow during 24 weeks of intervention, follow-up every 4 weeks.

Full description

With the trend of aging population and progressive increment of obesity in Vietnam, the number of patients suffering from osteoarthritis most likely will substantially increase in the coming years. Therefore, it is necessary to having a suitable and effective approach of treatment for osteoarthritis by using functional foods.

Proteoglycan is the basic substance of articular cartilage. Proteoglycans are mostly found in the extracellular matrix of animal tissue as cartilage, or in the blood vessels and brain. These substances are a key ingredient in the regeneration of cartilage, inhibiting the enzyme elastase - an intermediate that causes degenerative articular cartilage and reduces the formation of free oxygen radicals in cartilage tissue. Therefore, the effects are on inhibiting cartilage calcification, regenerating cartilage and relieving pain for cartilage degeneration, promoting cartilage metabolism, forming cartilage.

Previous studies have demonstrated that proteoglycan enhances fluid not only to alleviate arthritis pain but also prevent complications, as it gradually overcomes the damage of joint bone, resolves inflammation, helps relieve pain and prevent osteoarthritis, osteoporosis effectively. Otherwise, industrially extracted Proteoglycans presents to be safe and valuable for future studies of its function. Therefore, this randomized, double-blind controlled trial is conducted in Vietnam to assess the efficacy and tolerability of Proteoglycan F in the treatment of primary knee osteoarthritis.
