Detailed Description

Arthritis is an inflammation of one or more joints that is characterized by pain, stiffness (especially in the early morning or after exercise), swelling, deformation, and/or reduced mobility. Osteoarthritis, also known as degenerative arthritis, is caused by abnormal damage to the cartilage at the ends of bones. Some patients are caused by injury or congenital abnormalities in the proteins that make up cartilage.

Once the cartilage tissue changes from smooth to rough, or into small pieces. Cartilage is gradually destroyed, and the normally smooth surface becomes irregular. Osteoarthritis usually occurs in joints that require weight load, such as the spine, knees, hips and back, and is usually preceded by some pain and Symptoms of stiffness (mostly stiffness first, then pain), but swelling is not necessarily present. However, a small number of them will cause disability, but once the bones become more fragmented, they are more likely to cause fractures. When osteoarthritis is more severe, the bones can overgrow into osteophytes, known as bone spurs. When bone spurs develop, they can be detected with X-rays, usually in the neck or waist near degenerative cartilage. Formation, these phenomena will not produce any changes in appearance.

Osteoarthritis usually does not occur in adults under the age of 40. Most patients are over the age of 60. Symptoms may be so mild that you are unaware of them until detected by X-ray. The incidence is almost higher in women than in men. three times. Degenerative arthritis is increasing among the elderly in Taiwan. It has become a very important health problem and directly affects the quality of life. Pain control can improve the quality of life.

Previous studies have shown that orally administered hyaluronic acid (HA) can bind to toll-like receptor 4 (TLR-4) on intestinal epithelial cells, thereby increasing the secretion of the anti-inflammatory cytokine IL-10 and suppressor of cytokine signaling 3 (SOCS3), while suppressing the expression of the pro-inflammatory cytokine pleiotrophin, ultimately alleviating osteoarthritis. Regarding the regulation of cartilage degradation-related factors, HA can reduce irregularities on the cartilage surface as well as the loss of cartilage tissue and chondrocytes by suppressing the mRNA expression of MMP-3, MMP-9, and MMP-13 in cartilage tissue. In terms of oxidative stress, HA may also alleviate cartilage damage by downregulating inducible nitric oxide synthase (iNOS), thereby reducing nitric oxide (NO) production, and by inhibiting cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) production. To further enhance its efficacy in improving osteoarthritis, hyaluronic acid was combined with glucosamine and chondroitin. Previous studies have demonstrated that these two ingredients can improve connective tissue function and reduce cartilage matrix degradation. Therefore, the aim of this study was to investigate the effects of A+HA premium oral hyaluronic acid drink on improving knee pain.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Points change of pain evaluation scale
Time Frame: From the start to the end of treatment at 12 weeks
Self-assess pain using a visual analog scale (VAS), which is a straight line 10 cm in length, with 0 cm on the left representing no pain and 10 cm on the right representing extreme pain. Explain to the subjects that the pain intensity increases from left to right. Ask the subjects to mark the point on the line that corresponds to their pain level, and then record the distance in centimeters from the 0 cm mark. Record the points that the subjects wrote.
From the start to the end of treatment at 12 weeks
Points change of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
Time Frame: From the start to the end of treatment at 12 weeks
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a widely used questionnaires used by health professionals to evaluate the condition of patients with osteoarthritis of the knee and hip, and the total score was 96 points (Minimum: 0 points; Maximum: 96 points). The question content was divided into three parts: Pain (20 points), Stiffness (8 points), and Physical function (68 points). The higher score meant worse knee joint function. Record the points that the subjects got.
From the start to the end of treatment at 12 weeks
