Figure 1.

Representative arthroscopic images of 10 mm diameter, 10 mm deep osteochondral defect in the distal lateral trochlear ridge of the femur grafted with a synthetic biphasic cartilage repair device (CRD) immediately following implantation (D), and at 4-month (E), and 12-month (F) recheck arthroscopies. Full-thickness 10 mm diameter chondral defect treated with microfracture in the contralateral limb served as control; defect creation (A), 4-month (B), and 12-month (C) arthroscopic images. Fissures in native cartilage surrounding defect (black arrow). *Indicates the patella.
