Fig. 6From: Effect of proximal translation of the osteotomized tibial tuberosity during tibial tuberosity advancement on patellar position and patellar ligament angleVertical patellar position measurement. Patellar position was measured as the distance (mm) from the midpoint of the patellar articular surface perpendicular to the common tangent of femoral and tibial condyles. Note that this radiograph is blinded in that the degree of proximalization is not visibleBack to article page
