Brief Summary:
The presence of Staph in/on a patient who will undergo total joint replacement is a risk in that the patient could go on to develop infection at the surgery site after surgery. The purpose of this study is to evaluate if it is beneficial to to administer a questionnaire and obtain cultures from various body sites from patients prior to surgery and also to determine which body site(s) provide the best source of possible staph presence. If the pre operative cultures indicate staph is present, an Infectious Disease specialist will be consulted for standard of medical care consultation and treatment management. All patients scheduled to have total joint arthroplasty are eligible to participate. The research team will follow the study patients for 2 years after they undergo prosthetic joint implantation to monitor for development of prosthetic joint infection.

Primary Outcome Measures :
  1. Development of surgical site infection. [ Time Frame: Change in surgical site from baseline at 6 months, 1 year, 18 months and 2 years. ]
    The patient will be assessed by phone every 6 months for 2 years for development of infection at the surgical site.

Secondary Outcome Measures :
  1. Anatomical site(s) which are best utilized for swab cultures to detect S aureus. [ Time Frame: Up to 24 months post operatively. ]
    We hope to determine which anatomical site(s) are best utilized for swab cultures to detect S aureus colonization in patients undergoing prosthetic joint replacement. We will collect data on infection development for up to 2 years post operatively.

  2. Post operative infection (s.aureus) development. [ Time Frame: Up to 24 months post operation. ]
    We will measure at what percentage a pre-operative questionnaire accurately predicts if a patient will develop an infection (s.aureus) between day one and 2 years post operatively.
