Soft Tissue Reconstruction of Weight-Bearing Foot Defects
Summary
Soft tissue reconstruction of weight-bearing foot defects presents a unique surgical challenge due to the specialised anatomy and biomechanics of the plantar surface. The plantar skin is glabrous, richly innervated and subjected to repetitive loading, requiring reconstruction that restores both cushioning and protective sensation. Surgical strategies range from local and locoregional flaps to free microvascular transfers, each selected on the basis of defect size, location, vascular status and patient comorbidities. Local flaps such as medial plantar artery flaps exploit adjacent glabrous tissue, preserving contour and sensation but are limited by defect dimensions. Free flaps—including muscle, fascio-cutaneous and perforator designs—offer versatile options for larger or composite defects, with choices such as anterolateral thigh or lateral arm flaps tailored to recipient requirements. Critical considerations include flap durability under shear forces, restoration of two-point discrimination and minimisation of donor-site morbidity. Adjunctive methods, including acellular dermal matrices and vacuum-assisted dressings, have emerged to augment coverage in high-risk patients. Optimal outcomes rely upon interdisciplinary planning, meticulous microsurgical technique and rehabilitation protocols that facilitate early weight bearing and protect reconstructed sites.

Soft Tissue Reconstruction of Weight-Bearing Foot Defects publication trend
The graph below shows the total number of articles in soft tissue reconstruction of weight-bearing foot defects across all publications each year (not limited to Nature Index journals).
Technical terms
Free flap: A tissue transfer in which skin, muscle or composite tissue is completely detached from the donor site and re-anastomosed to recipient vessels via microsurgery.
Locoregional flap: A flap harvested from tissue adjacent to the defect, transferred on its native blood supply to the reconstruction site.
Fascio-cutaneous flap: A flap comprising skin and underlying fascia, offering thin, pliable coverage with potential sensory innervation.
Two-point discrimination: A measure of cutaneous sensory function assessing the minimal distance at which two stimuli are perceived as separate points.
