One-Step Approach for Infections After Achilles Tendon Open Repair: The Distally Based Peroneus Brevis Muscle Flap

Abstract

The aim of this single-center, retrospective study is to demonstrate the effectiveness of distally based peroneus brevis muscle flap as first therapeutic option for infections after Achilles tendon open repair. We retrospectively analyzed 14 consecutive patients with complete Achilles tendon rupture and developing surgical site infection after an attempt of open surgical repair. Every patient was reconstructed with distally base peroneus brevis muscle flap. The primary outcome was the return to work and the initiation of full weight-bearing. Secondary outcomes were complication rate and time needed to return to work. A review of the literature was conducted to better define the actual standard treatment. Each patient returned to work. No flap necrosis occurred. Two minor healing delays and one hematoma were reported. Median time to wound healing was 17 days (interquartile range [IQR] = 13-20). Median time to full weight-bearing was 52 days (IQR = 47-55). Median follow-up (FU) was 21 months. Distally based peroneus brevis flap is a safe treatment for surgical site infections after Achilles tendon rupture repair. Patients regained full weight-bearing after a median time of 52 days from the surgical reconstruction. No major complications were observed. This flap clearly emerges as first reconstructive option for complications after surgery of Achilles tendon region.
