The purpose of this study is to analyze how common stress hyperglycaemia (abnormally high blood glucose) is in primary hip and knee replacement surgeries and which factors predispose to hyperglycaemia.

Further study details as provided by Coxa, Hospital for Joint Replacement:

Primary Outcome Measures:
  • Occurrence (and severity) of hyperglycemia following primary hip or knee replacement [ Time Frame: 3 days (average) ]
    Follow-up covers postoperative hospital stay at the operating hospital, that lasts typically 2-5 days.

Secondary Outcome Measures:
  • Incidence of surgical-site infections [ Time Frame: 1 year ]
  • Prevalence of glucose metabolism disorders and metabolic syndrome [ Time Frame: Baseline ]

Biospecimen Retention:   Samples Without DNA
plasma sample (one per patient, collected before surgery)

Enrollment: 193
Study Start Date: December 2009
Study Completion Date: September 2012
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Hip and knee replacements recipients
Osteoarthritis patients undergoing elective primary hip and knee replacement and being followed-up in this study.

Detailed Description:
Postoperative infections remain one of the most frequent reasons of failure of hip and knee prostheses. Diabetes increases the risk of infections. In other fields of surgery, hyperglycemia induced by surgical stress (stress/perioperative hyperglycemia) has been associated with higher rates of postoperative infections and complications. Such studies have not yet been performed in the field of joint replacement surgery. Unlike several other risk factors of infected joint replacements, hyperglycemia is potentially modifiable and therefore its prevalence, predisposing factors and association with postoperative infections are of interest.
