No
The summary describes a mechanical knee replacement system and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.
No.
The device is an orthopedic implant (knee replacement system), which is a medical device intended to restore function and relieve pain, but not typically classified as a "therapeutic device" in the sense of delivering therapy. It is a long-term implant.
No
The device is a total knee replacement system, intended to aid surgeons in relieving knee pain and restoring function, not diagnosing conditions.
No
The device description explicitly states it is comprised of physical components (femoral and tibial components made of CoCr alloy and UHMWPE) and does not mention any software component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is part of a total knee replacement system used in surgery to treat knee pain and restore function. This is a therapeutic device implanted in the body.
- Device Description: The description details the materials and components of a knee implant (femoral and tibial components made of CoCr alloy and UHMWPE). These are physical implants, not reagents or instruments used to test samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information based on laboratory testing.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a surgical implant used to replace a damaged joint.
N/A
Intended Use / Indications for Use
This device is part of a total knee replacement system utilized in treating patients who are candidates for primary cemented total knee arthroplasty or revision arthroplasty where bone loss is minimal and the collateral ligaments are intact. It is intended to aid the surgeon in relieving the patient of knee pain and restoring knee joint function.
- Noninflammatory degenerative joint disease including osteoarthritis or traumatic arthritis
- I Avascular necrosis of the femoral condyle
- Post-traumatic loss of joint configuration, particularly when there is patellofemoral 제 erosion, dysfunction or prior patellectomy
- 배 Moderate valgus, varus or flexion deformities
- I Rheumatoid arthritis
- Treatment of fractures that are unmanageable using other techniques.

Device Description
The 3D Knee is comprised of a femoral and a tibial component. The femoral component is manufactured from CoCr alloy conforming to ASTM F75, is available in 6 sizes (2-12) and is provided in left and right configurations. The femoral component is designed to match the condyles of the tibial insert for greater congruency and is similar to the Foundation Knee cleared in K923277.
The 3D Knee tibial inserts are manufactured from ultra high molecular weight polyethylene (UHMWPE) that conforms to ASTM F648. The tibial inserts are available in 6 sizes (2-12) and 5 thicknesses (9-19) and are provided in right and left orientations. The tibial in design to the Foundation Lateral Pivot Insert cleared in K000590. This insert is intended to more closely complement the kinematics of the resurfaced knee, allowing rotation about the lateral condyle and increased congruency of the lateral condyle. The baseplate attachment mechanism is the previously cleared Foundation Knee System inserts; therefore, the attachment strength is the same.

§ 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.

Dear Ms. Droege:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
