Augmentation of soft tissue repairs has been helpful in protecting surgically repaired tissues as they heal. FlexBand (Artelon, Marietta, Georgia) is a synthetic, degradable, polycaprolactone-based polyurethane urea (PUUR) matrix that has been investigated and used for soft tissue repair in a variety of settings. The purpose of this study was to evaluate the safety profile of a PUUR matrix in a large cohort of patients undergoing soft tissue repairs about the foot and ankle.
Methods
A retrospective chart review of consecutive patients who underwent surgery using FlexBand to augment a soft tissue repair was performed to evaluate for major and minor complications related to the PUUR matrix. Results. A total of 105 patients with an average >6 months follow-up were included. The most common procedures were spring ligament repair, Achilles tendon repair, and Brostrom. There were 12 complications. Four major complications occurred with only 1 requiring PUUR matrix removal. Patients with wound complications had a higher body mass index (BMI) and rate of smoking.
Conclusion
Complication rates involving PUUR matrix in soft tissue foot and ankle reconstruction procedures are low and comparable with historical complication rates. The PUUR matrix is safe for use in a variety of soft tissue procedures about the foot and ankle.
