How Can Arthritis Change Your Knee?
Osteoarthritis can affect the whole joint, including cartilage, underlying bone and the synovial lining. Changes vary and are not simply inevitable wear from aging. This illustrates one type of arthritis.

What the illustration shows
A navy-and-gold educational poster titled “How Can Arthritis Change Your Knee?” The subtitle specifies osteoarthritis. Two similar front-facing selected knee cutaways compare a reference joint with possible osteoarthritis changes. Ivory femur and tibia surround pale-blue surface cartilage and separate darker blue meniscal wedges. The central tibial eminence is not covered by the blue plateau coating. Labels identify the femur, tibia, surface cartilage and a meniscus on the left. On the right, labels point to a localized roughened cartilage patch, a small bony spur continuous with the outer tibial margin, and peach joint lining inside the blue capsule. A note says the patella and front tissues are not shown. Below, one enlarged window shows surface cartilage over bone beside an attached marginal spur; another labels the outer capsule, its inner synovial lining and joint space. Text says osteoarthritis is one type of arthritis, changes vary, and it is not simply inevitable wear from aging. It also states that the illustration is not a severity scale or diagnosis. Gold AllHumanBody.com branding and the complete slogan appear on a plain navy footer.
How to interpret this poster
- Patella/front tissue omitted in selected cutaways. Not autoimmune arthritis, pain-source diagnosis, inevitable progression or activity/treatment advice.
- AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
- Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
