Abstract : Rotator cuff injury can cause a pain and permanent trauma of the head of the humerus, which ultimately leads to arthritis and a decrease of quality of life of patients. Shoulder arthroscopy is the "gold standard" of orthopedics in the treatment of articular pathologies. At the same time, the issues of tactics of surgical treatment, the choice of methods of operations, have not been fully resolved. They require the development of a technique for plastic surgery of the rotator cuff and bone structures of the shoulder joint. Improving the results of treatment of patients with pathologies of the rotator cuff of the shoulder joint by developing new methods of surgical treatment. Investigation was conducted at the Republican Specialized Scientific and Practical Center for Traumatology and Orthopedics, Uzbekistan from 01/01/2015 to 12/30/2021. 82 patients diagnosed with a full-thickness RCT were selected for study. To evaluate the effectiveness and monitor treatment, subjective methods were used: UCLA, Constant Shoulder Score and Simple Shoulder Test. The results before surgery and after 18 months were analyzed. The operation technique arthroscopic subacromial decompression, installation of an autograft from the tendon m. tensor fascia latae of the thigh and fixation of the autograft into the subacromial space. Medium term results of mini-invasive surgical treatment were analyzed. In 38 patients of main group (n=42), positive results were obtained (good result - 32 patients, satisfactory - 6). The complication rate was 8% and included 4 cases of persistent pain during rotational movements above the head afterwards. The diagnostic method and surgical treatment of RCT of the shoulder is convenient and simple, affordable. Allows for painless rotational movements of the shoulder joint, reduces re-traumatization of the RC with a minimally invasive and highly effective way.
