We report a case of septic arthritis of the shoulder joint treated by arthrotomy followed by open wound and early motion exercie. The patient was a 55-year-old male taxi driver. The infecting organism was methicillin-resistant staphylococcus aureus. At first he was treated by arthroscopic debridment which had no effect. Then we performed arthrotomy followed by open wound and early motion exercise. This open wound method was successful for infection. Concomitant antibiotics were administrated. We think arthrotomy followed by open wound and early motion exercise is a useful method for treating arthritis of the shoulder.
