Intended Use
The Kinemax® Plus Tibial Spacers are intended to be used with the tibial baseplates of the Kinemax® Plus and Kinemax® Plus Superstabilizer total knee systems in primary or revision total knee replacement procedures where there is bone loss on the tibia that requires augmentation for stability. The spacers may be cemented to the baseplate, or may be mechanically locked into place with fixation screws or fixation pegs. The baseplate-spacer assembly is then cemented onto the prepared proximal tibia.
Device Description
There are three types of spacers in the Kinemax® Plus Tibial Spacer System: a half spacer, a full spacer, and a full angled spacer. These spacers are fabricated from cast Vitallium® allov. The fixation screws and pegs used to secure these spacers to the tibial baseplates are fabricated from wrought or cast Vitallium® alloy. These products will be sold sterile.
More Information

No
The document describes a mechanical implant (tibial spacers) made of metal alloy, with no mention of software, algorithms, or data processing that would indicate AI/ML. The "Mentions AI, DNN, or ML" field is explicitly "Not Found".

No.
The device is a component of a total knee replacement system used to augment the tibia during surgery, not to treat or cure a disease or condition as typically defined for a therapeutic device.

No

The device is a tibial spacer, intended for use in total knee replacement procedures to augment bone in cases of bone loss. Its function is structural (to provide stability) rather than diagnostic.

No

The device description clearly states the spacers are fabricated from cast Vitallium® alloy and the fixation screws and pegs are fabricated from wrought or cast Vitallium® alloy, indicating a physical hardware device.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Description and Intended Use: The Kinemax® Plus Tibial Spacers are described as implants used in total knee replacement surgery. They are physically placed within the patient's body to augment bone and provide stability.
  • Lack of Diagnostic Testing: The description does not mention any testing of biological samples or providing diagnostic information.

Therefore, this device falls under the category of a surgical implant, 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.

Device: Kinemax® Plus Tibial Spacers

The Kinemax® Plus Tibial Spacers are intended to be used with the tibial baseplates of the Kinemax® Plus and Kinemax® Plus Superstabilizer total knee systems in primary or revision total knee replacement procedures where there is bone loss on the tibia that requires augmentation for stability. The spacers may be cemented to the baseplate, or may be mechanically locked into place with fixation screws or fixation pegs. The baseplate-spacer assembly is then cemented onto the prepared proximal tibia.

There are three types of spacers in the Kinemax® Plus Tibial Spacer System: a half spacer, a full spacer, and a full angled spacer. These spacers are fabricated from cast Vitallium® allov. The fixation screws and pegs used to secure these spacers to the tibial baseplates are fabricated from wrought or cast Vitallium® alloy. These products will be sold sterile.

The Kinemax® Plus Tibial Spacers are substantially equivalent to other legally marketed products. Examples of these products are listed below:
