Many patients with frozen shoulder who come to the clinic are afraid and worried when they hear that they need surgery. In addition to the effect of surgery, they are also worried if the doctor has told them that the disease is serious, so when do they need surgery? Based on my clinical experience, I can give you a little advice. 1. The pain is obvious at night and affects sleep. This includes pain that prevents sleep and waking up after falling asleep and turning over because of pain. Sleep is even more important than diet, so it is more serious if it affects sleep. 2.Loss of 50% of function. In other words, the arm is raised below the level of the shoulder or at the level of the shoulder, and it is difficult to reach back and touch the belt, which makes it difficult to put on clothes and other daily life. 3.The duration of the disease is more than 3 months. If all of the above 3 points are reached, it is necessary to operate, and according to my experience, the effect of the operation will be very good within 3 months or about 3 months, and even can recover completely normal, while more than 3 months, although also can get satisfactory results, but most of the recovery is not more than 90%. Of course, if the symptoms are not that heavy, you can continue conservative treatment and observation, after all, the surgery is aimed at the patient’s symptoms. 4, The only imaging mentioned is if it is an MRI (magnetic resonance imaging) If a rotator cuff tear or glenoid labrum injury is found, surgery is necessary. 5. Surgery after trauma or surgery causing shoulder pain and functional limitation is best within 3 months for a more satisfactory outcome. Another important reason that may affect the patient’s surgery is the cost, which is more affordable for the patient due to our health insurance system. You can consult about the cost of the surgery and the specific surgical procedure. It is important to mention that the surgery is minimally invasive surgery – arthroscopic treatment.
