Can you get gout (sp?)in a replaced knee joint?

In general no: in general no but gout deposits of monosodium urate can be present in many locations, including around a joint in the tendons if not in the joint. Your physician can help clarify this or have you see a rheumatologist who can clarify the findings. The diagnosis of gout in a joint is made by demonstrating the presence of the monosodium urate crystals in the joint.
