What is the main purpose of synovial fluid?

The main purpose of synovial fluid is to lubricate joints, which is crucial for facilitating smooth and pain-free movement between the articulating surfaces of bones in synovial joints. Synovial fluid reduces friction during movement, allowing for a wide range of motion while protecting the cartilage and underlying bone from wear and tear.

While synovial fluid does have secondary roles, such as providing some nutrients to the cartilage, its primary function remains lubrication. This lubrication minimizes the risk of joint damage, helps absorb shock during impact, and contributes to overall joint health. The presence of synovial fluid is essential in maintaining the efficiency and effectiveness of our movements, particularly in weight-bearing and dynamic activities.
