Single-Stage Arthroscopic Cartilage Repair With Chondrectomy and Implantation of a Templated Membrane Collagen Scaffold With Bone Marrow Aspirate Concentrate Augmentation (AMIC Plus).

Single-staged cartilage repair techniques have shown great clinical efficacy in the treatment of articular cartilage defects of the knee, particularly when using bilayered acellular scaffolds augmented with bone marrow aspirate concentrate. We describe an all-arthroscopic approach to the single-staged cartilage repair procedure using a porcine-derived collagen I/III bilayered scaffold that is templated arthroscopically and augmented with bone marrow aspirate concentrate, in the treatment of critically sized articular defects of the knee.
