Further study details as provided by Hvidovre University Hospital:

Primary Outcome Measures:
  • migration of the prosthesis in millimeters assessed vith RSA. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    does the use of a tourniquet around the thigh during insertion of a primary TKA affect postoperative migration of the prosthesis?


Secondary Outcome Measures:
  • postoperative pain. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Does the use of a tourniquet affect postoperative pain, patient satisfaciton and knee range of motion

  • Patient satisfaction (VAS-scale) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Does the use of a tourniquet affect postoperative pain, patient satisfaciton and knee range of motion

  • Knee range of motion (degrees) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Does the use of a tourniquet affect postoperative pain, patient satisfaciton and knee range of motion


Estimated Enrollment: 60
Study Start Date: January 2012
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: with tourniquet Procedure: tourniquet
a tourniquet around the thigh is used during insertion of the TKA to achieve a bloodless environment
Placebo Comparator: without tourniquet Procedure: no tourniquet
a tourniquet around the thigh is not used during insertion of the TKA
