Claim:
1. A method for forming a mold for use in repairing a defect in a bone, the defect having a surface that defines a volume within the bone, the method comprising: receiving imaging data obtained using a medical imaging technique, the imaging data representing the bone and a defect in the bone, the defect including a cavity in the bone; creating a three-dimensional (3D) model of a mold for an implant based on the imaging data, the mold including a cavity that replicates the volume and shape of the cavity of the defect, the mold further including a first portion having a first surface that matches the surface of the defect defining the volume, and a second portion having a second surface for defining a portion of an articular surface at the location of the defect; forming the mold based on the 3D model; and creating a 3D model of a guide based on the imaging data, the guide being configured to position a cutting tool relative to the bone as the cutting tool is used to create a void in the bone, the guide includes a nesting surface configured to engage the surface of the defect defining the volume to position the guide relative to the bone.
