An adjustable tibial osteotomy jig, comprises a goniometer, and the goniometer further comprises first an second arms, each arm having a base. A pivot movably connects the arms at the bases. The pivot has a bore passing through it. A proximal and distal cutting guide are mounted on the first and second arms, respectively. The cutting guides each have a slot to receive a saw blade. Each cutting guide is clamped in a predetermined position along its respective arm. One or more pins pass through the holes in the proximal cutting guide and into a tibia, for fixing the proximal cutting guide in a first predetermined position with respect to the tibia. One or more pins pass through the holes in the distal cutting guide for fixing the distal cutting guide in a second predetermined position with respect to the tibia The surgeon passes the blade of a saw through the slots of the cutting guides, which results in a cut removing a wedge-shaped piece of bone from the tibia.
