Heat map of the occurrence of the infrapatellar branches of the MFCN and ISN on the right knee. The x-axis represents the percentage of the width of the treatment box lateral to the patella; the y-axis represents the percentage of the length of the treatment box inferior to the patella; and the z-axis indicates the number of nerve branches occurring at each location. The superior, inferior, medial, and lateral boundaries of the treatment box as determined by Le Corroller are defined as y = 0, y = 100, x = 0, and x = 100, respectively, and are denoted by the dotted black box. The majority of nerve locations determined using TENS occur within the area bound by the dotted white box. The dotted yellow line denotes the proposed treatment line
