title: The Use of All-Arthroscopic Autologous Matrix-Induced Chondrogenesis for the Management of Humeral and Glenoid Chondral Defects in the Shoulder.
abstract: Autologous matrix-induced chondrogenesis (AMIC) is often used for treating chondral defects in different joints. We describe an all-arthroscopic approach for the treatment of glenoid and humeral chondral lesions with this technique. AMIC starts with the use of microfractures of the damaged cartilage, followed by coverage of the defect with a type I/III collagen matrix (Chondro-Gide; Geistlich Pharma, Wolhusen, Switzerland) that is fixed with fibrin glue (Tissucol; Baxter, Warsaw, Poland). In a 1-step approach, the unstable cartilage is debrided, microfractures that penetrate up to the subchondral bone are performed, and the membranes are pasted to the lesion. Our technique reduces morbidity rates compared with traditional open surgery. The arthroscopic AMIC procedure is a viable, cost-effective treatment for the repair of chondral lesions of the shoulder.
