The fluid in the knee is called synovial fluid.
Understanding Synovial Fluid
Synovial fluid, also known as joint fluid, is a viscous liquid found between the joints, including the knee. According to the reference, its primary functions are to cushion and protect the ends of bones, reducing friction during movement. Typically, there is only a small amount of synovial fluid present in the joints.
Key Functions of Synovial Fluid:
-
Lubrication: It reduces friction between the cartilage and other tissues in joints to lubricate and cushion them during movement.
-
Nutrient Transport: Synovial fluid supplies nutrients to the cartilage.
-
Shock Absorption: It acts as a cushion to protect the joint during impact.
Abnormalities in Synovial Fluid:
Changes in the amount or quality of synovial fluid can indicate underlying problems such as:
- Infection
- Arthritis
- Other joint disorders
