Simplex High Viscosity Bone Cement in Primary Total Knee Arthroplasty

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02572310

Brief Summary:
In this study the investigators propose to monitor subjects who have received Triathlon total knee components inserted with HV cement. The primary outcome will be fixation of the tibial implant component as assessed with RSA and to determine the functionality of patients after surgery using self-reported questionnaires. This is a historical control study, comparing the study cohort to a previous group with Triathlon implants and the long-standing Simplex T cement. The secondary outcomes are inducible displacements of the implants as well as a qualitative evaluation of the cement handling characteristics performed by the operating room staff.

Primary Outcome Measures :
  1. Implant Migration measured with Radiostereometric Analysis (RSA) [ Time Frame: 2 years ]
    Total implant migration will be measured in mm using RSA

Secondary Outcome Measures :
  1. Qualitative handling characteristics captured through semi-structured interviews [ Time Frame: intra-operative ]
    A qualitative methodology will be used to perform content analysis of the audio from the interviews stored in computer-assisted qualitative data analysis software. The content analysis will involve the use of a deductive approach to the interviews. The coding strategies will derived from a predetermined list of important qualities of bone cement and common themes will be identified as important for the usability of the new cement.
