Schöttle point on a lateral view of the right knee. Using a perfect lateral view on fluoroscopy, the surgeon identifies the femoral insertion point, or Schöttle point, which lies just anterior to the posterior femoral cortex extension line (line 1), approximately 2.5 mm distal to the posterior border of the medial femoral condyle (line 2), and just proximal to the level of the most posterior point of the Blumensaat line (line 3).²¹ This point represents the anatomic insertion of the medial patellofemoral ligament on the femur.⁴ We use an Arthrex medial patellofemoral ligament template to precisely identify the Schöttle point.
