“…Therefore, according to our series, incisions medial to the reference line with a minimum distance of 20 mm, 10 mm, 10 mm and 0 mm from Points 1, 2, 3 and 4, respectively, would be safe to perform (Table 4 ). Proximal zones and points may be useful in revision surgery or chronic Achilles tendon rupture surgery [ 16 , 31 , 41 , 44 ] or in some Achilles tendon lengthening techniques [ 7 , 10 , 19 , 41 ]. The central zones may be useful in acute Achilles pathology surgeries [ 12 , 22 , 35 , 47 ] and distal zones in arthroscopic surgeries [ 2 , 23 , 34 ] or ankle fractures [ 18 , 29 , 33 ].…”
