SPECT-CT for Assessment of Total Knee Arthroplasty in Navigated and Non-navigated Total Knee Arthroplasty


By the comparison of two operation methods navigated and non-navigated TKR with SPECT/CT we want to show wich method has the better outcome.

Full Title of Study: “SPECT-CT for Assessment of Patients Before and After Navigated and Conventional Total Knee Arthroplasty.”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: July 2017

Detailed Description

With SPECT/CT we want to controll the clinical outcome of patients who underwent a navigated or a non-navigated TKR.


  • Procedure: TKR
    • non-navigated versus computer-navigated total knee replacement

Arms, Groups and Cohorts

  • SPECT/CT before/after navigated TKR
    • SPECT/CT in patients before and after navigated TKR (assessment of bone tracer uptake, 3D CT component position)
  • SPECT/CT before/after conventional TKR
    • SPECT/CT in patients before and after conventional TKR (assessment of bone tracer uptake, 3D CT component position)

Clinical Trial Outcome Measures
