Some help: There is normally cartilage between the bones in the knee. If it is gone (mild joint space narrowing) in whole or part, the bones grind on each other and there is inflammation making fluid come into the joint (small joint effusion), and the bones show scar (mild subchondral sclerosis). It's not good.

Djd: Those findings are c/w degenerative joint disease,ie your knee has some wear on the ant and medial sides. As the cartilage wears down the joint space gets narrowed. the bone directly under the space thickens (sclerosis) in response to increased load. Inflammation leads to swelling (effusion). These are early signs of degenerative joint disease. You're on young side to have arthritis.

It sounds: like mild degenerative arthritis/osteoarthritis.
