Intended Use
1) Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis, traumatic arthritis where one or more compartments are involved. 2) Correction of varus, valgus, or posttraumatic deformity. 3) Correction or revision of unsuccessful osteotomy, arthrodesis, or failure or previous joint replacement procedure. The device is indicated for implantation with cement.
Device Description
The Narrow Ascent™ Interlok® Femoral Components are primary femoral components intended for use with an Ascent™ tibial component and patella for total knee replacement. The device is manufactured from cast cobalt alloy (Co-Cr-Mo) conforming to ASTM F-75 with Biomet's Interlok®, 30 grit blasted finish. Three sizes, x-small, small, and medium are available in left and right configurations. The device varies from the predicated device in that the width of the component in the medial-lateral direction has been reduced by approximately 4mm. This has been accomplished by reducing the width of each condyle by approximately 2mm. All other dimensions remain the same. A narrower femoral component is desired to avoid overhang of the device in a patient with a naturally narrow femur.
More Information

No
The summary describes a mechanical knee implant with a design modification (reduced width) and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The device is a knee replacement component intended to correct painful and disabled knee joints resulting from various conditions, which aligns with the definition of a therapeutic device as it treats a medical condition.

No
The device is a femoral component for total knee replacement, intended for surgical implantation to treat painful and disabled knee joints. It is a therapy device, not a diagnostic one.

No

The device description clearly states it is a physical femoral component made of cast cobalt alloy for total knee replacement, not software.

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 treating knee joint conditions. This is a therapeutic device, not a diagnostic one.
  • Device Description: The description details a physical implant (femoral component for total knee replacement) made of metal. IVD devices are typically reagents, instruments, or software used to examine specimens from the human body.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting markers, or providing diagnostic information.

Therefore, this device falls under the category of a surgical implant or prosthetic device, not an In Vitro Diagnostic.

§ 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.
