Intended Use
To reduce or relieve pain and restore function and motion to the knee joint. Total knee replacement is indicated for patients with severe knee pain and disability due to rheumatoid arthritis, osteoarthritis, primary and secondary traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral condyle or pseudogout, posttraumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy, moderate valgus varus or flexion deformities.

No
The summary describes a total knee replacement device and its intended use, focusing on traditional surgical methods and predicate devices that rely on bone cement. There are no mentions of AI, ML, image processing, or any data-driven analytical components.

Yes

Explanation: The device is indicated to "reduce or relieve pain and restore function and motion to the knee joint," which are therapeutic outcomes. It is a knee replacement, a surgical intervention aimed at treating severe knee conditions.

No

The device is a total knee replacement, which is a therapeutic device designed to relieve pain and restore function, not to diagnose a condition.

No

The 510(k) summary describes a total knee replacement device, which is a physical implant, not a software-only device. The summary focuses on the intended use for surgical intervention and references predicate devices that are also physical implants.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to "reduce or relieve pain and restore function and motion to the knee joint" through total knee replacement. This describes a surgical procedure and the function of an implanted device within the body.
  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections. The provided information does not mention any such testing.
  • Device Description: While the device description is "Not Found," the intended use clearly points to a physical implant for surgical use.
  • Lack of IVD-related information: There is no mention of samples, assays, reagents, or any other elements typically associated with IVD devices.

The information provided describes a surgical implant used for total knee replacement.

§ 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.

  • Intended Use: .
    To reduce or relieve pain and restore function and motion to the knee joint. Total knee replacement is indicated for patients with severe knee pain and disability due to rheumatoid arthritis, osteoarthritis, primary and secondary traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral condyle or pseudogout, posttraumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy, moderate valgus varus or flexion deformities.

  • Comparison to Predicate Devices: .
    See attached chart.

  • Clinical and Nonclinical Uses: .
    Current methods of implant fixation rely on the use of bone cement. Numerous studies reported in literature indicate satisfactory results have been obtained through use of devices to which substantial equivalence is claimed.
