Small suprapatellar joint effusion mild right lateral joint space narrowing and spurring of the articular surfaces?

Osteoarthritis. It sounds like you are reading the x-ray report of someone with knee osteoarthritis. Joint space narrowing = cartilage loss. Spurring = bone spurs. Suprapatellar joint effusion = typical small amount of extra joint fluid seen in osteoarthritis. Sounds like a mild to moderate case.
