Angelo had massive shortening from a congenital deformity and has worn a prosthesis all his life. However, the valgus deformity of the right limb has made prosthetic wear difficult and has compromised his function. Notice the angular deformity (figure 3) demonstrated by the 2 orange lines.
He underwent an osteotomy of the proximal tibia to straighten the leg.
With a straight leg, prosthetic wear, function, and aesthetics have all been improved for Angelo. Notice a straight orange line in Figure 4 representing the mechanical axis of the right lower extremity.
