Adipose Tissue Transfer in Dynamic Definition Liposculpture Part II. The Lower Limb: Gastrocnemius, Vastus Medialis, Vastus Lateralis, and Rectus Femoris Muscles

Abstract

Background: One big challenge of body contouring surgery is the liposculpture of the lower limbs, probably because of the imperative symmetry and the risk of contour irregularities. We are reporting our experience in fat grafting of the thighs and calves for men and women undergoing dynamic definition liposculpture. Methods: We did cadaveric dissections of the vastus lateralis, vastus medialis, rectus femoris, and gastrocnemius muscles and identified each of their primary pedicles. We also performed fat grafting of these muscles in the contralateral virgin cadaveric specimen. We searched our records for patients who underwent fat grafting of the lower extremity in addition to dynamic definition liposculpture, from January 2016 to May 2022 at a single center in Bogotá, Colombia. Results: Seventy-three consecutive patients met the inclusion criteria (26 men and 47 women). We grafted 102 gastrocnemius muscles, 86 vastus medialis muscles, 98 vastus lateralis muscles, and 22 rectus femoris muscles. Mean age was 34 and 41 years for men and women, respectively. Range of the fat graft volume was 50–200 mL. No complications were recorded related to fat grafting. Almost all patients were satisfied with the procedure (89%). Follow-up period ranged from 2 to 36 months. Conclusions: Fat grafting of the lower limb muscles should be considered an alternative operative technique to enhance volume and athletic appearance of this body segment. Based on cadaveric dissections and clinical evidence, our technique is considered reliable and reproducible with remarkable outcomes and a very low complication rate.
