Psoriatic arthritis psoriatic arthritis, and affect them symmetrically. Involvement of the spinal joints is more suggestive of psoriatic arthritis than rheumatoid arthritis. Osteoarthritis shares certain clinical features with psoriatic arthritis such as its tendency to affect multiple distal joints in an asymmetric pattern. Unlike psoriatic arthritis, osteoarthritis does not typically involve inflammation of the sacroiliac joint. Psoriatic arthritis sometimes affects only one joint and is sometimes confused for gout or pseudogout when this happens. There are five main types of psoriatic arthritis: The underlying process in psoriatic arthritis is inflammation; therefore, treatments are directed at reducing and controlling inflammation. Milder cases of
Septic arthritis as longer lasting infections cause more destruction to the joint. The involved organism, age, preexisting arthritis, and other comorbidities can also increase this risk. Gonococcal arthritis generally does not cause long term impairment. For those with "Staphylococcus aureus" septic arthritis, 46 to 50% of the joint function returns after completed antibiotics. In pneumococcal septic arthritis, 95% of the joint function will return if the person survives. There is also one-third of the people at risk of functional impairment (due to amputation, arthrodesis, prosthetic surgery, and deteriorating joint function) if they have underlying joint disease or having synthetic joint implant.
