Roturas masivas del manguito de los rotadores: resultados clínicos de la reparación artroscópica con técnica doble MAC

Abstract

BackgroundMassive ruptures of the rotator cuff represent one of the most complex lesions that can be faced by the orthopaedic shoulder surgeon, and pose a great challenge to achieve satisfactory clinical results. The aim of this study is to describe the clinical outcomes of a new surgical technique for the repair of large and massive rotator cuff injuries used in a specialised orthopaedic clinic during a period of 3 years. Materials and methodsA descriptive study was carried out on a cohort of patients with large and massive lesions of the rotator cuff, diagnosed by direct arthro-resonance, and who met criteria for arthroscopic repair. They underwent repair using a new technique called double MAC (Mason-Allen configuration). The post-surgical outcomes were measured using the Constant scale, and the presence of complications and the level of patient satisfaction with the procedure were analysed as outcomes. ResultsThere were 21 patients (10 men and 11 women) with mean age of 59.4 (SD: 8.2) years at the time of surgery. A supraspinatus rupture was present in all (100%) of patients, and an infraspinatus rupture was present in 42.8%.. The mean size of the tear was 34.5 mm (SD: 11.2). Mean time between surgery and assessment was 9 months. Mean post-operative Constant score was 77.4 (SD: 9.0). There were no surgical complications or anchor failure. An early adhesive capsulitis was diagnosed and managed with articular mobilisation, with subsequent improvement in range of motion. DiscussionDouble MAC technique for arthroscopic repair of large and massive RCT is a safe and effective technique, with good clinical outcomes in the medium term and a patient satisfaction of over 90%.
