Fig 3.

A 3- to 4-cm longitudinal incision is made over the superior border of the patella (black dashed line) in a left knee, and dissection is performed past layers 1 and 2. By use of a 2.4-mm drill bit, the proximal anchor is placed at the superior one-third of the proximal patella. This process is repeated for placement of the distal anchor, which is about 0.75 cm distal to the proximal anchor. During placement of the proximal and distal suture anchors, counterpressure (white arrow) is placed on the lateral border of the patella for increased stability.
