A Multicenter Study to Evaluate Functional Outcome After Knee Replacement

Not Applicable

Terminated

• Conditions: Osteoarthritis
• Interventions: Device: Off the Shelf Total Knee Replacement; Device: ConforMIS iTotal Knee Replacement

• Registration Number: NCT02494544
• Lead Sponsor: Restor3D

Brief Summary

Patients will be consecutively enrolled by implant. Implant groups will be those who have undergone surgery with either a ConforMIS iTotal® CR TKA or an Off-the- Shelf (OTS) system.

The patient will conduct functional testing and answer questionnaires.

The results will compare the ConforMIS iTotal with an Off the Shelf Knee replacement.

Detailed Description

To compare functional and patient reported outcome data for a consecutively enrolled group of subjects who have undergone surgery with either a ConforMIS iTotal® CR TKA or an Off-the- Shelf (OTS) system.The person conducting the functional testing will be blinded to the device implanted. Sites will perform the off-the-shelf total knees conventional instrumentation.
