title: Anterior-inferior shoulder instability: treatment based on the Thal method.
abstract: Purpose of this study is to analyze the results of a consecutive series of 139 patients affected with anterior-inferior shoulder instability and treated by arthroscopic capsuloplasty using the Thal method with absorbable and non-absorbable Mitek knotless anchors. Much attention was paid to the preoperative and intraoperative selection of patients, excluding from the arthroscopic procedure those with bony Bankart lesions measuring more than 25%, with an inverted-pear glenoid, with engaged Hill-Sachs lesions and patients with HAGL lesions. Pre- and postoperative clinical evaluation was carried out using the Rowe scale. Scores rose from 45-55 to 96 postoperatively. Intra-articular mobilization of the anchors did not occur and peri-metallic lysis was not manifested. Areas of bone resorption were observed in 7 cases (7/38, 18.4%) with the presence of peri-insertional geodes with biological anchors, but this had no effect on the clinical results.
