The soreness and discomfort of the knee joint may be the problem of meniscus injury, or it may be degenerative osteoarthritis. It can be considered to go to the orthopedic department of the hospital for examination in time, and improve the routine X-ray examination of the knee joint to see if there is obvious degenerative osteoarthritis. If meniscus injury is considered, it is necessary to consider that magnetic resonance examination is helpful to determine the condition, and corresponding follow-up treatment can be performed according to the examination results. If it is degenerative osteoarthritis, you can choose glucosamine and other drugs to protect articular cartilage. If the meniscus injury is not serious, the local use of blood activating and stasis removing drugs can be selected, such as Yunnan Baiyao aerosol. If the meniscus injury is obvious, arthroscopic treatment should also be considered when necessary. Avoid long distance walking and strenuous exercise at ordinary times, which is conducive to the health of the knee joint.
