Primary Outcome Measures :
  1. Surgical Site Infection (SSI) [ Time Frame: 2016-2017 ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Sampling Method:   Non-Probability Sample
Study Population
All adults greater than 18 years undergoing total knee arthroplasty from January 2016 to December 2017 at Aga Khan University were included in this study. A standardized proforma was used to collect data from online patient data system about patients' preoperative, intraoperative and postoperative details. Preoperative data included age, gender, and comorbid conditions. Intraoperative data was collected from the surgical and anaesthesia records and included surgical site, American Society of Anesthesiologists (ASA) Level, duration of surgery, preoperative body temperature, intraoperative body temperature and duration of surgery. Postoperative data included post-operative body temperature and whether the patient developed any surgical site infection.

Inclusion Criteria:

  • All adults greater than 18 years who underwent total knee arthroplasty.

Exclusion Criteria:

  • Any patient below 18 years
