The knee joint is an important joint for human activities, and it is subject to pressure from various sources, both in daily life and in sports, as well as occasional “bump” injuries and sometimes more serious trauma, which can cause different degrees of damage to the joint. In addition, due to the development of the “O” leg or “X” leg, sometimes it is not easy to find. This lower limb deformity, even if mild, usually causes the normal line of gravity of the lower limb to shift inward or outward, resulting in uneven forces on the medial and lateral surfaces of the knee joint, thus increasing the stress on the corresponding joint surface and causing wear and tear. In addition, as we age, especially in middle-aged and elderly women, due to age and menopause, there is often a greater increase in weight, which can also increase the burden on the knee joint. In cases where the knee joint is painful or has developed osteoarthrosis, early consultation should be made at a major hospital or at a hospital with a specialist for a clear diagnosis and timely treatment. Oral glucosamine and chondroitin sulfate are usually used to protect the joint cartilage, reduce the inflammatory response of the joint and relieve joint pain. The above methods are clinically effective for both early and mid-stage osteoarthrosis patients.
