Background: The medial sural artery perforator (MSAP) flap is an increasingly versatile and reliable flap for soft tissue reconstruction. This study investigates complication rates and long-term outcomes of the MSAP flap.
Methods: A retrospective review was performed on consecutive patients undergoing MSAP flap reconstruction at Chang Gung Memorial Hospital from 2006 through 2017. Patient demographics were assessed. Flap failure and wound complications were the outcome measures.
Results: In the cohort of 246 patients that underwent a total of 248 MSAP flap reconstructions were identified. The average age was 47.5 years (range 15-76). Of the 248 flaps, 170 were used for reconstruction of the head and neck, 48 for upper extremity reconstruction, and 30 for lower extremity reconstruction. The average MSAP flap size was 5.2 × 11.8 cm. 31 (12.5%) of the flaps developed arterial occlusion, venous insufficiency, or a hematoma postoperatively requiring re-exploration. Nineteen were successfully salvaged, yielding an overall failure rate of 4.8%. Minor complications included the need for flap debridement in 18 cases (7.3%) and need for donor site debridement in eight cases (3.2%).
Conclusions: The MSAP flap can be used in a versatile fashion to reconstruct defects of the head and neck, upper extremity, and lower extremity with minimal complication rates.

Medial Sural Artery Islanded Pedicled Perforator Flap for Resurfacing Areas in the Popliteal Fossa Following Postburn Contracture Release Using Normal versus Scar Tissue.

The medial sural artery perforator (MSAP) flap is reliable in resurfacing defects of the popliteal fossa. There is possibility of resurfacing the popliteal fossa defects after postburn contracture release with scarred MSAP flaps with good overall long-term outcomes. A study was conducted from June 2017 to July 2023 to evaluate the functional and surgical scar aesthetic outcome in patients with soft-tissue defects in the popliteal fossa after postburn contracture release that were reconstructed using scarred and unscarred MSAP flap with 10 patients in each group.

Background: The medial sural artery perforator (MSAP) flap is thin, pliable, and versatile. This study aims to understand the anatomical basis of the MSAP flap and the subcutaneous course of the perforator for safe flap thinning.
Methods: A total of 24 MSAP flaps were dissected under red silicone dye injection guidance.

Article Synopsis
- - The study explores how leg dominance affects the choice of perforator flap donor sites for reconstruction surgeries using advanced imaging techniques to enhance preoperative planning.
- - In a sample of 40 patients, most (87.5%) were right-leg dominant, showcasing that the dominant leg typically has larger and more numerous perforators for certain flap types compared to the nondominant leg.
- - Results suggest that surgeons may benefit from prioritizing the dominant leg as a donor site, as it has better vascular characteristics and muscle thickness for improving surgical outcomes, although no significant differences were found in the subcutaneous tissue thickness.

Objective: Defect reconstruction of the hand by means of the free medial sural artery perforator (MSAP) flap.
Indications: Reconstruction of full-thickness defects on the hand with a thin non-bulky flap in cases of exposure of functional structures or in combination with simultaneous osteosynthetic procedures.
Contraindications: Prior surgery at the donor site or progressive peripheral artery occlusive disease.

Purpose: Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) presents significant challenges, especially in elderly and comorbid patients, often necessitating revision surgeries. We report on a series of patients with confirmed PJI of the knee and concomitant soft-tissue/extensor apparatus defects, treated by using pedicled myocutaneous medial or lateral sural artery perforator (MSAP/LSAP) gastrocnemius flaps.
Methods: Our retrospective study at the Center for Musculoskeletal Infections, included patients with knee PJI undergoing pedicled myocutaneous MSAP/LSAP gastrocnemius flap reconstruction for combined soft tissue and extensor apparatus defects.
