    AbstractLocal muscle flaps are especially advantageous when treating soft tissue defects, but one disadvantage is the potential functional deficits associated with the muscle transfer. In this study, we evaluated ankle function among patients (cases) who underwent reconstruction of soft tissue defects in the leg using local flaps of the gastrocnemius and/or soleus muscle. Function was compared between the affected and contralateral non-affected limb and against patients (controls) with open tibial fractures who required no soft tissue reconstruction. In a retrospective cohort study, ankle function was accessed as range of motion (ROM) and plantar flexion strength, and using American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot summation and subscale scores. Among 31 patients who underwent soft-tissue reconstruction, 19 were available for functional evaluation. Controls were 23 patients with open tibial fractures not requiring flaps. Among cases, reconstruction was performed with a soleus flap in nine patients, a medial gastrocnemius flap in seven, a lateral gastrocnemius in one, and with both gastrocnemius and soleus flaps in one patient each. One patient developed partial flap necrosis. In cases, ankle dorsiflexion and plantar flexion were significantly decreased on the affected versus normal side. However, no deficit in plantar flexion strength was detected; nor any significant difference in AOFAS ankle-hindfoot scores in cases versus controls. Local muscle flaps are useful for reconstructing post-traumatic soft tissue defects in the leg. Some loss of ankle ROM should be expected, but likely no clinically-measurable deficit in overall ankle strength and function.Copyright © 2023 The Author(s). Published by Elsevier Ltd..
