With the development of medical technology, China has stepped into an aging society. The treatment and prevention of cancer and cardiovascular diseases are of more concern. Musculoskeletal joint diseases are often easy to be ignored. Many people encounter neck and back pain, shoulder pain, tennis elbow, and heel pain. Some people consider them to be minor diseases and do massage or herbal compresses to relieve the symptoms without seeking medical attention, which often leads to improper treatment of the disease into the chronic phase, which affects work and life in the long run. Ultrasonography is an effective method for diagnosing various musculoskeletal joint diseases that many clinicians and patients ignore. Ultrasonography is not only fast and accurate in diagnosing musculoskeletal joint diseases, but also allows local guidance for drug treatment. Because of the accuracy of ultrasound guidance, clinical treatment efficacy has been greatly improved. High concentration platelet injections for degenerative knee diseases under ultrasound guidance can largely relieve pain and degenerative exacerbation of the disease and delay replacement of the knee joint, which is one of the important means of joint health care. Ultrasound technology is increasingly becoming a powerful tool for rehabilitation physicians and a second stethoscope for physicians. It is effective in treating all kinds of neck, shoulder, lumbar and leg pain, sports injuries, and god-level injuries.
