As the weather gets cooler, the number of people with shoulder pain increases significantly. Due to the lack of knowledge about shoulder diseases, unexplained shoulder pain is often arbitrarily diagnosed as “frozen shoulder”. In fact, most of the causes of shoulder pain are not “frozen shoulder”. In fact, “frozen shoulder” is not a generic term for unexplained pain around the shoulder joint, but is more accurately named “frozen shoulder” or “adhesive capsulitis”. Most patients may have mild symptoms at the beginning of the disease and may experience pain during activity. The pain may radiate from the shoulder to the forearm, worsen when lifting or holding heavy objects, and may occur in athletes when throwing or playing tennis. When the pain continues to develop, it will produce nighttime pain, unable to lift the shoulder and unable to lift the hand over the head as the main manifestation, for example, the patient is restricted in activities such as taking items from the shelf, tying a bra or strap behind the hand of female patients, taking the alarm clock at the bedside, etc. In severe cases, the affected limb cannot comb the hair and wash the face. If the symptoms are not treated in time, a vicious cycle will occur and the shoulder pain and restricted activities will become more and more obvious, seriously affecting daily life. The shoulder joint is a very complex joint and is the most mobile and flexible joint in the human body. The main reason why many patients suffer from shoulder pain for a long time without relief is that the diagnosis of the disease is not clear and the treatment is not effective. At present, many shoulder pains are vaguely defined as “frozen shoulder”, and most of the treatment methods are physical therapy, such as acupuncture, massage, physical therapy, plastering or asking patients to “exercise more”. In fact, the real “frozen shoulder” only accounts for 10-15% of the causes of shoulder pain. The main causes of shoulder pain are rotator cuff disease, subacromial impingement, calcific tendonitis, shoulder instability, and shoulder dislocation in that order. Most shoulder disorders can now be treated minimally invasively under arthroscopy. Shoulder arthroscopy is a high-tech minimally invasive treatment technique for shoulder joint diseases that started to develop in the 21st century. It can be applied to the diagnosis and treatment of frozen shoulder, rotator cuff injury, calcific tendonitis, biceps tendon injury, shoulder free body, synovitis, septic arthritis, osteoarthritis and other diseases. Like other arthroscopic surgeries, special shoulder arthroscopic instruments and equipment are required. It requires a shoulder arthroscopy specialist to select 2-3 surgical entrances of about 5 mm in length in the shoulder joint area and implant the shoulder arthroscope and surgical instruments shoulder arthroscope, which has the advantages of clear diagnosis, precise surgery, and surgical implantation of fixed consumables without the need for secondary surgery to remove them. In addition, this technique is characterized by non-bleeding, minimally invasive operation to clean and repair the lesions in the shoulder joint, which can preserve the function of the shoulder joint to the maximum extent, and the patient can recover quickly after the operation, and can quickly carry out rehabilitation exercises and daily activities, which is very popular among patients with shoulder joint diseases.
