Efficacy of Orthoplastic Management in the Treatment of Traumatic Popliteal Artery Injury.

Abstract

Popliteal artery injury (PAI) is a challenging condition. Even with appropriate initial treatment and reconstruction of the associated injuries, extensive soft-tissue necrosis may occur, requiring lower leg amputation. There are no reports on the effectiveness of orthoplastic surgery in treating traumatic PAI. However, orthoplastic surgery is also considered very effective in PAI treatment, which requires delicate handling of soft-tissue and blood vessels. This study aimed to examine the treatment outcomes of traumatic PAI at a trauma center with the capacity for orthoplastic management. Patients with PAI who were treated at our institution between August 2013 and December 2021 were included in this study. The surgeons included multiple orthoplastic surgeons with capabilities in vascular repair, bone and ligament reconstruction, and soft-tissue reconstruction. Patient demographics, injury characteristics, degree of ischemia, and treatment were investigated. We also investigated whether soft-tissue reconstruction and lower limb amputation were necessary as outcomes of treatment. Fifteen limbs of 14 patients with PAI met the inclusion criteria. Extensive soft-tissue necrosis was observed in three limbs. Two of these limbs were covered with a free latissimus dorsi flap and could be salvaged. In the remaining limb, lower limb amputation was unavoidable because of unexplained cardiac arrest during the initial surgery, but a fillet flap was used to successfully preserve the knee joint. Orthoplastic management has the potential to improve limb salvage rates and provide good outcomes for the treatment of traumatic PAI.
