View through a mini-medial parapatellar arthrotomy of the right knee in the supine position showing a 2 × 2.5-cm cartilage lesion. A Paulsen retractor (∗) is placed along the medial aspect of the medial femoral condyle retracting the soft tissues and a sharp bent Hohman (∗∗) is placed in the intercondylar notch in order to retract the patella. (A-B) A 10-mm diameter metal sizing tamp (Y) with its end colored by a marking pen is used to mark the locations of the recipient site harvests (Χ). Care is taken to leave a 5-mm osteochondral bridge (arrow) between graft sites.
