Arthroscopic Cartilage Repair of the Patella With Minced Cartilage and Collagen Membrane Scaffold With Bone Marrow Aspirate Concentrate.

The single-staged repair technique of patellofemoral cartilage lesions has previously been described, with the utility of a bilayer scaffold and minced cartilage via an open mini-arthrotomy, showing great clinical efficacy. We describe a procedure similarly aimed at addressing patellofemoral lesions but with an all-arthroscopic approach, using a porcine-derived collagen I/III bilayer scaffold augmented with bone marrow aspirate concentrate and minced cartilage.
