Risk of permanent impairment of the joint varies greatly. This usually depends on how quickly treatment is started after symptoms occur 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<unk> , 46 to 50% of the joint function returns after completing antibiotic treatment. In pneumococcal<unk> , 95% of the joint function will return if the person survives. One-third of people are at risk of functional impairment (due to amputation, arthrodesis, prosthetic surgery, and deteriorating joint function) if they have an underlying joint disease or a synthetic joint implant. Mortality rates generally range from 10-20%. These rates increase depending on the offending organism, advanced age, and comorbidities such as rheumatoid arthritis.
