A member asked:

What is the difference between water on the knee and knee swelling?

2 doctors weighed in across 2 answers
Dr. Jack Choueka answered

Specializes in Orthopedic Surgery

Different locations: Fluid can be within the knee joint which is called a knee effusion. This is usually comes from an injury. Knee swelling refers to the soft tissues around the knee and represents a more chronic condition.

Same: Water on the knee might imply swelling within the joint. Knee swelling might be inside or outside of the joint.
