A 74-year-old man presents to A&E with an acutely swollen, red wrist

A 74-year-old man presents to A&E with an acutely swollen, red wrist. He has no history of trauma and said he woke up in the middle of the night with the pain and saw that his wrist was swollen. He has a very limited range of movement in his wrist joint. It is decided to get a synovial fluid sample to diagnose the problem.
