The summary describes a traditional knee implant system made of standard materials, with no mention of software, algorithms, or any technology related to AI or ML.
Yes
The device, a total knee system, is intended to alleviate severe knee pain, correct deformities, and replace damaged knee components, which are all therapeutic actions.
No
The device is a total knee replacement system, which is a therapeutic device designed to replace damaged knee joint components, not to diagnose a condition.
No
The device description clearly states that the Freedom® Total Knee System is comprised of physical components made of materials like Cobalt-Chromium-Molybdenum and ultra high molecular weight polyethylene, which are implanted into the knee joint. This indicates it is a hardware medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for replacing parts of the knee joint in patients with severe knee pain and disability due to various conditions. This is a therapeutic intervention performed in vivo (within the body).
- Device Description: The device is described as a physical implant (femoral component, tibial component, patellar component) made of materials like Cobalt-Chromium-Molybdenum and UHMWPE. These are materials used for surgical prosthetics.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples) to provide information for diagnosis, monitoring, or treatment. IVDs typically involve reagents, analyzers, or test kits used in a laboratory or point-of-care setting.
In summary, the Freedom® Total Knee System is a surgical implant, not a device used for in vitro diagnostic testing.
N/A
Intended Use / Indications for Use
The Freedom® Total Knee System consists of a femoral component, poly tibial component, and a patellar component. The Freedom® Total Knee System is indicated for patients with severe knee pain and disability due to:
- Severe knee joint pain, loss of mobility, and disability due to: rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis.
- Correction of functional deformities.
- Post-traumatic loss of knee joint contour, particularly when there is patellofemoral erosion, dysfunction, and/or prior patellectomy.
- Moderate valgus, varus, or flexion trauma.
- Knee fractures untreatable by other methods.
This system is intended for cemented use only.

Device Description
The Freedom® Total Knee System is comprised of a femoral component (cruciate retaining and posterior stabilizing), all-poly tibial component and a patellar component as described below.
The Freedom® Total Knee System's Femoral component is offered in both cruciate retaining and posterior stabilizing designs. The Femoral components are available in right and left configurations, and eight sizes to accommodate varying anatomy. The Freedom® Total Knee System's Femoral Component is made of Cobalt-Chromium-Molybdenum and is intended for cemented application to replace the articulating surface of the distal femur in a measured resection.
The Freedom® Total Knee System's Tibial baseplate component is fabricated from ultra high molecular weight polyethylene and is intended for cemented application to replace the articulating surface of the proximal tibia in a measured resection. Both the Total Knee System CR and PS Tibial Inserts have identical locking mechanisms to mate with the Tibial Base Plate. The Freedom® Total Knee System Patellar component is available in a symmetric design fabricated from industry standard UHMWPE (ASTM F648). Testing of the Freedom® Total Knee System has been performed out to 135 degrees which demonstrates high flexion of the total knee device.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
