When the chondral lesion is assumed at the weight bearing area of the medial or lateral femoral condyle, the anterior portion of the sulcus terminalis (the groove for meniscus) in the middle section of the lateral condyle is considered to be the optimal donor site.

This study suggests that osteochondral graft stability may influence the histologic properties of the repaired cartilage. It is preferable to implant the slightly oversized graft into the cartilage lesion in autologous osteochondral transplantation to preserve the histologic properties of cartilage.
