Antibiotic Regimen for Type 1 Open Fracture of the Patella

First-Line Antibiotic Selection

For Gustilo-Anderson type I open fractures, a first-generation cephalosporin such as cefazolin is the recommended first-line agent, as suggested by the American College of Surgeons 1, 2
Cefazolin effectively targets the most common pathogens in open fractures, including Staphylococcus aureus and streptococci, with a standard dosing of 2g IV slow, and an additional 1g if the surgical procedure lasts longer than 4 hours 2, 1

In cases of allergy to beta-lactams, clindamycin 900mg IV slow is the recommended alternative, according to the American Academy of Orthopaedic Surgeons 1
For patients with severe beta-lactam allergies, vancomycin 30mg/kg over 120 minutes can be used, as recommended by the Infectious Diseases Society of America 1

Antibiotic therapy should be limited to the operative period, with a maximum duration of 24 hours, as recommended by the Surgical Infection Society 1

Delaying antibiotic administration beyond 3 hours post-injury significantly increases infection risk, as reported by the American College of Surgeons 2
Adding aminoglycosides is unnecessary for type I open fractures and should be reserved for type III open fractures, according to the American Academy of Orthopaedic Surgeons 3, 2
Using antiseptics or soap additives for initial wound irrigation provides no benefit over simple saline solution, as suggested by the American Academy of Orthopaedic Surgeons 3
