Psoriatic arthritis of psoriatic arthritis include the following: Other symptoms that are more typical of psoriatic arthritis than other forms of arthritis include enthesitis (inflammation in the Achilles tendon (at the back of the heel) or the plantar fascia (bottom of the feet)), and dactylitis (sausage-like swelling of the fingers or toes). Several conditions can mimic the clinical presentation of psoriatic arthritis including rheumatoid arthritis, osteoarthritis, reactive arthritis, gouty arthritis, systemic lupus erythematosus, and inflammatory bowel disease-associated arthritis. In contrast to psoriatic arthritis, rheumatoid arthritis tends to affect the proximal joints (e.g., the metacarpophalangeal joints), involves a greater number of joints than
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.
