Freedom Total Knee System Registry for Knee Osteoarthritis

This study is an observational registry looking at the safety and effectiveness of the MAXX Orthopedics, Freedom Total Knee® System after it's been approved for use. It's for people aged 18 and older who have knee osteoarthritis and have not found relief from other treatments. You would be scheduled to receive a total knee replacement (Total Knee Arthroplasty) using the Freedom Total Knee System. The main goal is to see how well the device works and lasts for at least two years after surgery. The study aims to enroll 300 participants, but the current recruitment status is unclear.

Study design
This is an observational study, meaning researchers will monitor patients who receive the Freedom Total Knee System. It plans to enroll 300 participants.
What's involved
You would undergo a total knee replacement surgery. Your progress and the performance of the knee system would then be monitored.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed to assess how long the device lasts, with measurements taken at 2 years.

What this trial measures

  • Device Survivorship2 years

    Revision / re-operation post-operatively due to device / device composite failure. An anticipated benefit of the device is that it is more conforming at higher degrees of flexion, which could potentially result in reduced polyethylene wear and improved survivorship over the longer-term. To assess this aspect of the device in addition to safety over the short-, intermediate- and long-term, survivorship analyses will be conducted at the targeted follow-up landmark timepoints. There will be 3 survivorship endpoints: * Revision of any component (including insert) for any reason * Revision of any component (including insert) for any reason except infection
