Frozen shoulder is one of the most common causes of shoulder pain in middle-aged and elderly patients. Frozen shoulder is also known as “50 shoulder”, “frozen shoulder”, “frozen shoulder” and many other synonyms. It is a self-limiting disease, and most patients can be cured after one year’s course. Most patients can recover spontaneously after a year’s course. A few patients with serious conditions have poor treatment effects and are left with the sequelae of shoulder joint pain and dysfunction. Conservative treatment methods for frozen shoulder include: taking painkillers, non-steroidal anti-inflammatory drugs, internal and external treatment with traditional Chinese medicine, local closed injection, physiotherapy and sports rehabilitation training. The closure treatment of rostral synostosis has the best effect; patients with intractable frozen shoulder refer to those who have been ineffective after more than 6 months of the above regular conservative treatments, and have long time intractable pain, bone deformity, serious lesions or rupture of tendon, intra-articular adhesion and capsular contracture leading to serious dysfunction of shoulder joint, and those who have difficulty in tolerating the pain, should actively choose arthroscopic minimally invasive surgical treatments. Minimally invasive arthroscopic surgery is one of the fastest growing disciplines in the field of surgery and sports medicine in the last 25 years. The method of shoulder arthroscopic surgery is that the patient is under anesthesia for pain relief, and the surgeon performs arthroscopic surgery under direct visualization using a small in-depth arthroscope with a diameter of 0.5 cm in the shoulder joint and its specialized minimally invasive surgical instruments. Like other arthroscopic surgeries, it is performed by specially trained sports medicine doctors under the direct vision of shoulder arthroscope using specialized surgical equipment such as sutures and suture rivets to suture broken muscle and tendon tissues, to cut off contractured capsular ligaments, to excise proliferated bony cumbersome bones, and to combine with manipulation of the joints to loosen the joints; and combined with the orderly sports rehabilitation training methods after the surgery, to achieve the cure of the disease. Due to the advantages of arthroscopic shoulder surgery, such as accurate diagnosis of frozen shoulder, small trauma, precise surgery, no need for secondary surgery to remove the surgical implantation of fixed consumables, and remarkable effect, etc., it has greater advantages compared with the traditional incision surgery, and is favored by the majority of frozen shoulder patients. Patients with frozen shoulder who have been ineffective in conservative treatment for more than 6 months, and who suffer from muscle atrophy, dysfunction and severe pain can choose minimally invasive arthroscopic surgery, which has reliable curative effect.
