Abstract

We present the case of a 40-year-old patient from the Marrakech region who suffered a traumatic injury to the left lower limb in 2024. The injury led to a femoral shaft fracture treated with intramedullary nailing and a tibial plateau fracture treated with plate osteosynthesis. The patient subsequently developed a septic knee arthritis caused by Streptococcus agalactiae one year post-surgery. The patient was admitted to the emergency department with acute knee swelling, severe pain, and functional impairment. Joint aspiration revealed purulent fluid, and microbiological analysis confirmed the presence of Streptococcus agalactiae. The patient was treated with intravenous amoxicillin-clavulanate, and surgery for material removal and joint lavage was performed. This case underscores the importance of early diagnosis and treatment of joint infections following orthopedic surgery.
