A Schematic diagram of 19 planes along the midline for the lower limbs, 10 equal planes for the thigh and 10 for the crus; B Schematic diagram of the probe position for ultrasound-guided PP block. SM, sartorius muscle; VMM, vastus medialis muscle; LFCN, lateral femoral cutaneous nerve; aLFCN, anterior branch of lateral femoral cutaneous nerve; pLFCN, posterior branch of the lateral femoral cutaneous nerve; IPBSN, infrapatellar branch of the saphenous nerve; IFCN I;, intermediate femoral cutaneous nerve branch I;; IFCN II;, intermediate femoral cutaneous nerve branch II;; aMFCN, anterior branch of the medial femoral cutaneous nerve. Green circles represent the centre of the patella; blue box 1 represents the probe position for the LFCN block; blue box 2 represents the probe position for the IFCN I; block; blue box 3 represents the probe position for the IFCN II; block; blue box 4 represents the probe position for the aMFCN block; and blue box 5 represents the probe position for the IPBSN block
