Vascularized osteochondral graft from the medial femoral trochlea: anatomical study and clinical perspectives.

Purpose: Few donor sites for vascularized reconstruction of convex joint surfaces have been described. We studied the feasibility of a convex vascularized osteochondral graft harvested from the medial femoral condyle and trochlea, on an anatomical and practical point of view.

Methods: An injection-corrosion technique was used on 16 fresh cadaver specimens, and completed by a modified Spalteholz clearing.
