This is a comparison of the functional results and Varus-Valgus Stability in Single-radius versus Multi-radius Femoral Component for Total Knee Arthroplasty.


Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Study of Compare Mid-flexion Stability and Clinical Outcomes in Single-radius Femoral Design or Multi-radius Femoral Design.

Further study details as provided by Chonnam National University Hospital:

Estimated Enrollment: 213
Study Start Date: August 2010
Estimated Study Completion Date: July 2011
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Detailed Description:
Recently, femoral designs based on a sagittal single radius were designed to allow better mid-flexion stability and extensor function after total knee arthroplasty. The purpose of this study was to compare mid-flexion stability and clinical outcomes in patients that received TKA using either a single-radius femoral design or multi-radius femoral design.

Ages Eligible for Study:   48 Years to 84 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
56 total knee arthroplasties(TKAs) with a single-radius femoral design (Scorpio NRG) (single-radius(SR) group) and 59 total knee arthroplasties(TKAs) with multiradius femoral design (NexGen CR) (multi-radius(MR) group)

Inclusion Criteria:

  • followed for a minimum of two years.

Exclusion Criteria:

  • Not followed for a minimum of two years.
