Fasciocutaneous flaps offer a wide range of options for the reconstruction of lower-limb soft-tissue defects. This article presents the case of a 39‑year‑old patient who underwent sarcoma resection in the knee region, followed by reconstruction using a reverse sural flap. This regional flap is characterised by favourable retrograde perfusion, structural stability, and minimal donor-site morbidity, enabling single-stage defect coverage and protection of the deep structures of the knee joint. Free flaps are frequently considered the method of choice for the reconstruction of larger lower limb defects; however, their use may be limited in the presence of peripheral vascular disease, diabetes mellitus, post-traumatic wounds, or in patients with an increased risk of perioperative complications. In contrast, the reverse sural flap provides effective defect coverage, reduced operative time, and a lower risk of complications while preserving limb function. The presented case confirms that the reverse sural flap is a safe, effective, and practical option for lower‑limb soft‑tissue reconstruction, offering advantages over free microsurgical flaps in selected clinical scenarios.
