Varies: There are multiple potential causes for fluid in the knee. The fluid itself can be from an injury, inflammation, or other causes. Osteoarthritis is one type of arthritis. If there is concern about the nature of the fluid in the knee, it can be drawn out and sent to the lab to see what it is. An MRI is a test that can look for other associated conditions as well. Consider being seen.
