Guillain-Barré syndrome is an autoimmune disorder presented by ascending paralysis and areflexia. The condition has been reported after many infections, but Guillain-Barré syndrome after spine surgery is rare. We, herein, present a case of Guillain-Barré syndrome after multiple spine surgeries for degenerative lumbar scoliosis. A 60-year-old woman with degenerative scoliosis underwent surgery for the third time and developed Guillain-Barré syndrome 3 weeks after the final operation. The patient received intravenous immune globulin therapy and needed mechanical ventilation and intensive care. She was discharged in good condition after 5 weeks.

In this article, a 75-year-old patient with pain in left knee and restricted range of motion following total knee arthroplasty (TKA) is presented. Serological evaluation and aspiration of knee joint suggested a fungal prosthetic joint infection. After the diagnosis was confirmed, treatment started with antifungal drugs, removing prosthesis, exhaustive debridement, and revision of TKA after efficient antifungal treatment. At one-year follow-up, she has a painless motion range of 10 to 90 degrees, and there was no recurrence of infection observed.
