A method for repairing a defect area in a surface of a knee joint, the method comprising:
- providing a balloon mold having a first surface and a second surface, wherein at least the first mold surface is rigid;
- collapsing the balloon mold for insertion into the joint;
- expanding the balloon mold inside the joint by filling the mold with one of gas or fluid;
- positioning the balloon mold within the joint such that a perimeter of the balloon mold surrounds the defect area and the balloon mold completely covers the defect area;
- depositing a repair material external to the balloon mold from under the mold first surface and within the defect area to create a repaired site within the joint, the repaired site including a restored joint surface formed from the deposited repair material;
- and
- removing the balloon mold from within the joint, thereby uncovering the defect area and restored joint surface.
