Not Applicable

Completed

• Conditions: Knee Joint Pain
• Interventions: Device: Freedom Total Knee; Device: Total Knee Replacement; Device: Freedom Total Knee System

• Registration Number: NCT02056470
• Lead Sponsor: Maxx Orthopedics Inc

Brief Summary

Assess the safety and functionality of the Freedom Knee® system through a multi-center clinical trial. Study endpoints include a comparison of Pre-Surgery versus Post-Surgery data for:

1. Range of Motion

2. Quality of Life measurements using Knee Society Scale (KSS)

3. Survivorship as defined by 'No Revision' of baseline implant

4. Quality of Life measurements using the WOMAC Score

Detailed Description

The clinical study will involve a series of evaluations performed by your surgeon. These examinations are consistent with the normal surgeon care as part of Total Knee Replacement surgery. The study objective is to assess the safety, functionality, and survivorship of the Freedom Knee System through a multi-center clinical trial. Study endpoints include a comparison of Pre-Surgery (baseline) versus Post-Surgery data for Range of Motion and Flexion, Quality of Life (KSS), and survivorship (defined by 'no revisions'). Additionally, the structural integrity will be evaluated based on the x-ray performed 36-months after knee replacement.
