The Anterolateral Thigh Flap for Achilles Tendon Reconstruction: Functional Outcomes

Following Achilles tendon rupture and repair, reruptures or infections are not infrequent. Consequently, several surgical techniques have been described to decrease complication rates. This study aimed to evaluate the outcomes of the free composite fasciocutaneous anterolateral thigh flap including fascia lata for reconstruction of combined complex soft-tissue and Achilles tendon defects.

Within an 8-year period, 34 patients having undergone microvascular Achilles tendon reconstruction fulfilled inclusion criteria for this study: 25 of these patients (73.5 percent) returned for follow-up examination, seven of whom (28.0 percent) underwent additional bilateral contact pressure and power measurements. The data were screened for patients' demographics, intraoperative and perioperative details, flap survival, surgical complications, and overall long-term outcomes.

Mean follow-up time was 40.8 months. The Thompson test was negative in all patients. The pain score assessed by the Numerical Rating Scale at the reconstructed site was low overall, but showed significant differences between rest and activity (p < 0.05). The assessment of the Vancouver Scar Scale showed very good results with both techniques. The measurements of the peak pressures, power while walking, and foot contact area did not show differences between the operated and nonoperated sides (p > 0.05), whereas range of motion revealed significant differences (p < 0.05).

In patients who suffer complex Achilles tendon injury requiring free flap coverage, the composite anterolateral thigh flap including fascia lata provides a reliable and safe approach with very good functional and aesthetic outcomes. It should be considered one of the first reconstructive options.
