How Does Psoriatic Arthritis Affect the Knee?
The condition does not follow the same pattern in everyone. The symptoms, such as stiffness and painful swelling, may appear differently in each person. For example, some people with psoriatic arthritis of the knee will experience symptoms in one knee, while others will experience symptoms in both knees.
Psoriatic arthritis in the knee may also cause swelling in the ligaments, tendons, and synovial fluid in the surrounding area. Symptoms may also show up in the elbows, feet, and hands. Some people may notice slight stiffness or pain in just one of their knees, whereas others may have severe pain in both knees that makes it difficult to walk.
