The appointment time was set up that AM by phone because Dr. Khanuja had messaged me the Thursday night before asking me if I could come in Tuesday AM to have fluid drawn from my knee that had been replaced on February 24, 2025. His appointment people set up the appointment at 11:40 AM at White Marsh. I was ushered into an exam room at 11:50 AM. About 12:30 I stepped outside to see if I had been forgotten. Dr. Khanuja was at the counter working on his computer and indicated he would see me as soon as he could.
