What Is Psoriatic Arthritis?
Psoriatic arthritis is a condition that can develop in people who have psoriasis, and it affects many joints, including the knee. Psoriasis is a skin condition that causes skin cells to build up and form patches of itchy, dry skin called plaques.
If a person with psoriasis develops psoriatic arthritis as well, it may cause one or more joints, such as the knee, to become stiff, inflamed, and painful. Psoriatic arthritis is a long-term inflammatory disease. Symptoms may get progressively worse over time without effective treatment.
With the right treatment it is possible to slow the progress of the condition and reduce its symptoms. Early diagnosis is vital to minimize damage to the joints.
