I ruptured my achilles and had the repair surgery. 13 days later my wound opened up. Initially the cultures grew 3 types of bacteria. I had a three-week antibiotic regimen. After two surgeries for debridement and covering of the wound with Integra the tendon was no longer visible, but the wound wouldn't close. I'm not diabetic nor do I smoke. The skin graft failed. The doctor just ordered an MRI wondering if there's a deep pocket of infection with possible exploratory surgery.
