Vanguard Complete Knee Versus Vanguard High Flex Rotating Platform (RP) Knee Study
A Prospective Controlled Multi-center Study on Vanguard Complete Knee and Vanguard High Flex RP Knee

The purpose of this study is to compare Vanguard High Flex Rotating Platform to Vanguard Complete Knee System in Asian population in terms of early range of motion (ROM), clinical outcomes, and kinetic and kinematic characteristics in relation to healthy knees.

The primary objectives of this clinical study include:

  • Evaluate size fit and long term performance of Vanguard Complete Knee ("Fixed") System in Asian and Latino population in comparison to competitor's similar product.
  • Evaluate efficacy of Vanguard Complete Knee with Microplasty Tibial Tray.
  • Compare Vanguard High Flex Rotating Platform ("High Flex") Knee System to Vanguard Complete Knee System in Asian population in terms of:

    • Early ROM
    • Clinical outcomes
    • Kinetic and Kinematic characteristics in relation to Healthy Knees. o
  • Compare current design to new design of Vanguard High Flex Rotating Platform Knee System in terms of :

    • Early ROM
    • Clinical outcomes
    • Kinetic and Kinematic characteristics

Allocation: Non-Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Osteoarthritis
  • Rheumatoid Arthritis
  • Traumatic Arthritis
  • Device: Vanguard Complete Knee
    Vanguard Knee is a metal and polyethylene system indicated for cemented tibial and femoral use.
  • Device: Vanguard High Flex RP
    Vanguard High Flex RP is an extension to the existing Vanguard Knee and has been specifically designed to facilitate greater than 135 degrees of knee flexion.
  • Active Comparator: Vanguard Complete Knee
    Vanguard Completed Knee with Microplasty Tibial Tray is designed to hold the tibial knee bearings in a microplsty knee procedure. The Co-Cro-Mo trays are designed with a shorter stem.
    Intervention: Device: Vanguard Complete Knee
  • Active Comparator: Vanguard High Flex RP
    VGRD High Flex RP knee is an extension to the exsting Vanguard Knee and has been specifically desinged to facilitate greather than 135 degrees of knee flextion as required by certain patients.
    Intervention: Device: Vanguard High Flex RP
