Figure 6: Lateral Knee Denervation. A) Incision is shown, lateral to patella, centered over the tender site shown in Figure 3. Vastus lateralis is shown (short arrow). The iliotibial tract is incised (dotted line) to demonstrate the lateral retinacular nerve (long arrow) adjacent to the lateral recurrent geniculate vessels. B) The lateral retinacular nerve is illustrated. C) The nerve is first infiltrated with local anesthetic, and the cauterized distally and proximally, and then divided proximally below the level of the iliotibial band so that the nerve drops into the popliteal fossa.
