Because of the increasing use of prosthetic joints, infection associated with these devices has become the most common and challenging type of septic arthritis encountered by most clinicians. [2] The incidence of prosthetic joint infection (PJI) among all prosthesis recipients ranges from 2% to 10%. These figures may be falsely low because surveillance is limited to the operative hospital, which may lead to underestimation of the rate of PJIs. [3]

Patients who have undergone treatment for infection of a native joint are at an increased risk of developing PJI following a total joint arthroplasty of that particular joint. [4]

Septic arthritis is also becoming increasingly common among people who are immunosuppressed and elderly persons. Among individuals with septic arthritis, 45% are older than 65 years; these groups are more likely to have various comorbid disease states. Fifty-six percent of patients with septic arthritis are male.
