Treatment for rotator cuff tears includes both non-surgical and surgical treatments. Treatment usually begins with non-surgical treatment. Surgical treatment is often the first choice when a young patient has a rotator cuff tear due to trauma. In these patients, early surgical treatment is most effective. Generally, this condition means that the patient is younger than 50 years old and the injury is less than 4 weeks old. The non-surgical treatment of rotator cuff tears and impingement syndrome is similar, with the majority of patients showing significant improvement in symptoms with only initial non-surgical treatment. (1) Exercise therapy: The aim of exercise therapy is to strengthen the rotator cuff tendon, restore the mobility lost due to pain and inflammation by pulling, and restore the position of the humerus under the acromion to a better state in order to reduce the compression of the bursa. (2) Anti-inflammatory drug treatment: It can relieve pain and reduce inflammation. Many patients with rotator cuff tears improve significantly with physical therapy and medication to control pain, especially in the elderly and those with less demanding shoulder joints. (3) Steroid injections: If symptoms do not improve with physical therapy and medication, your doctor may recommend a steroid injection into the subacromial bursa. Cortisone or similar steroids are often used in combination with local anesthetic medications to control pain and bursal inflammation. Steroids should be used with caution. More than 2-3 steroid applications in a few months may damage rotator cuff tendon tissue. Diabetic patients are also not suitable for steroid injections. 2. Surgical treatment: Not all rotator cuff tears require surgical treatment. Many patients are satisfied with non-surgical treatment. If the patient is unable to regain shoulder mobility and effectively strengthen the surrounding muscles, surgical repair of the rotator cuff is required. This is usually done for younger, more active patients who need to improve the persistent weakness that follows physical therapy. Rotator cuff repair surgery can be accomplished through minimally invasive arthroscopic surgery or open surgery. Arthroscopic surgery is a newer technique and is not indicated for all types of rotator cuff tears. Open surgery to repair rotator cuff tears allows the rotator cuff tendon to be firmly fixed to the humerus. 3. What are the complications of surgery? The chances of complications from surgery are usually very low. Common complications include infection, hemorrhage, nerve damage and shoulder stiffness. Pre-operative antibiotics can reduce the incidence of post-expansion infection, and the rate of infection is slightly lower in arthroscopic surgery than in open surgery. The likelihood of hemorrhage or nerve injury is extremely low. Postoperative shoulder stiffness is the main complication of surgical treatment of rotator cuff tears.
