Intended Use
The U2 Total Knee system is indicated in knee arthroplasty for reduction or relief of pain and/or improved knee function in skeletally mature 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. This device may also be indicated in the salvage of previously failed surgical attempts if the knee cannot be satisfactorily balanced and stabilized at the time of surgery. For cemented femoral components, patellar components, tibial baseplate components and tibial inserts components: This device is a single use implant and intended for cemented use only. For porous coated femoral component: This device is a single use implant and intended for cementless use only.
Device Description
U2 Cemented Femoral Component-CR Type is manufactured from cast Co-Cr-Mo alloy confirming to ASTM F75. It is available in seven proportional sizes (#1~ #7, AP/ML ranging from 52mm/ 56mm to 76mm/ 80mm) and is provided in left and right configurations. The femoral component is the same as that of cleared U2 Total Knee System (K051640), except adding size #7. Fixation of the femoral component to the femur is achieved using bone cement.
More Information

No
The 510(k) summary describes a traditional knee implant system and does not mention any AI or ML components, algorithms, or functionalities. The performance studies are mechanical tests, not related to AI/ML performance.

Yes
The device is a knee arthroplasty system intended to reduce or relieve pain and improve knee function in patients with severe knee pain and disability, which aligns with the definition of a therapeutic device.

No

This device is a U2 Total Knee system, an implant used in knee arthroplasty to reduce pain and improve function in patients with severe knee pain and disability. Its purpose is to replace or salvage a joint, not to diagnose a condition.

No

The device description explicitly states it is a "U2 Cemented Femoral Component" manufactured from "cast Co-Cr-Mo alloy," which are physical hardware components for knee arthroplasty.

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 knee arthroplasty to treat various knee conditions. This is a therapeutic device, not a diagnostic one.
  • Device Description: The description details the materials and design of a knee implant (femoral component). This is consistent with a surgical device.
  • Lack of Diagnostic Elements: There is no mention of analyzing samples (blood, tissue, etc.), detecting biomarkers, or providing diagnostic information.
  • Performance Studies: The performance studies focus on the mechanical properties and function of the implant (range of motion, contact pressure, fatigue), which are relevant to a surgical device.

IVD devices are used to examine specimens from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a physical implant used to replace a damaged joint.

§ 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.
