An ongoing biomechanical study at the authors’ institution to characterize the contact pressure alteration and restoration following the autologous osteochondral transplantation procedure demonstrates that relative to the intact ankle (A), creating an osteochondral lesion significantly alters contact pressure about the ankle joint such that the pressure is shifted centrally when loaded (B). Placement of the autologous osteochondral transplantation graft into the site of the defect (C) restores loading to intact levels.
