Chapter 42 Video 2: Anteromedialization

January 23, 2017

Contributors: Jack Farr II, MD

In this example of an anteromedialization, there is a longer incision to allow for concomitant cartilage restoration. Proximally, a lateral lengthening is performed. The incision is carried along the lateral aspect of the tuberosity, and the anterior compartment musculature is elevated. An incision is made along the medial border of the patellar tendon and is continued obliquely as it courses distally. A cutting guide or jig is applied. The slope arm selects where the saw will exit along the lateral wall. A retractor protects neurovascular structures. The saw exits onto the retractor and is above or anterior to the posterior wall of the tibia. The jig is removed. The saw is then inserted into the cut, and the cut is used as a capture guide to continue proximal and distal extents of the osteotomy. Proximally the osteotomy is completed with an osteotome, changing directions as it moves from posterior to anterior. The free tuberosity can then be elevated and medialized and held temporarily with a pin. With the tuberosity in the desired position, it is then fixed with standard interfragmentary technique; typically two 4.5mm screws are used. The sharp proximal medial aspect of the tuberosity is trimmed. The amount of anteriorization is directly measured, as is the amount of medialization. The lateral compartment musculature is lightly reapproximated to tampenade the cancellous bone posteriorly. Proximally, the lateral lengthening is reapproximated.
