Study Description
Brief Summary:

In Denmark, approximately 13,000 operations are carried out every year. Prosthetic infection is a very serious condition and despite extensive prophylactic measures, prosthetic infections appear in 1-2 percent of the operated patients.

It is difficult to diagnose prosthetic infection with the techniques applied so far and incorrect diagnosis might imply unnecessary reoperations as well as unnoticed infections might lead to prolonged pain and invalidity.

The purpose of this study is to examine the value of these three techniques applied as a supplement to the existing technology and on this basis to prepare an algorithm for the examination of joint prosthesis infection.

Study Design

Study Type : Observational
Actual Enrollment : 60 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Surgical Field Bacterial Contamination in Primary Hip and Knee Replacement Surgery
Study Start Date : June 2010
Primary Completion Date : December 2010
Groups and Cohorts

Outcome Measures

Primary Outcome Measures :
  1. Contamination of the operation area [ Time Frame: 12 months ]
    We want to examine the existence of contamination before an operation in hip and knee. Furthermore, we want to examine the contamination to achieve better knowledge of the bacterial combination.

Secondary Outcome Measures :
  1. Description of the bacterial culture [ Time Frame: 12 months ]
    We want to describe the bacterial culture to achieve better knowledge of the bacterial combination.
