Comparison of the immediate and medium-term clinical outcomes of treatment of patients with partial-thickness rotator cuff tears of various depth and localization

Objective - To compare the effectiveness of conservative treatment, arthroscopic debridement and anchor fixation in patients with partial-thickness rotator cuff tears of various depth and localization.Material and methods. The study was a prospective randomized controlled one with the formation of three compared groups of 120 patients older than 55 years with MR-signs of an symptomatic isolated atraumatic partial tear of the supraspinatus tendon. Patients of group I were treated conservatively, group II - performed subacromial decompression, in group III, in addition to decompression, an anchor fixation was performed. Each group contained two subgroups of 60 patients with partial tears of the bursal (B-PTRCT) and articular surface of the tendons of the rotator cuff of the shoulder (PASTA, A-PTRCT), each of which was formed of four subgroups of 15 patients depending on the depth of the tendon tear: 90%. The observation was carried out for 12 months, assessing the functional state of patients before treatment, as well as after 3, 6 and 12 months...
