Summary: Targeted muscle reinnervation (TMR) is beneficial for decreasing pain following below-knee amputation (BKA). While most current literature describes the principles behind primary TMR, they provide few principles key to the amputation, as the BKA is usually performed by another surgeon. When the BKA and TMR are performed by the same surgeon, it can be performed through the same surgical access as needed for both procedures. The purpose of this article is to describe our anatomically based BKA technique in the setting of planned primary TMR as performed by 3, single, peripheral nerve plastic surgeons at 2 institutions. Advantages of the single-surgeon technique include efficiency in dissection, preservation of donor nerve length, limited proximal dissection, early identification of recipient motor nerves for coaptation, ability to stimulate these while still under tourniquet, and decreased tourniquet and operative time. This technique is quick, reliable, and reproducible to help promote widespread adoption of TMR at the time of BKA.
