Candidates for total knee replacement include patients with a severely disabled joint resulting from osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or a failed previous implant.
Device Description
The ATTUNE Cemented Tibial Base, Fixed Bearing (FB) are available in sizes 1-10. The fixation surface incorporates a stem and keel to provide additional stability as well as recessed undercut cement pockets and a grit blasted surface for enhanced cement fixation. The tibial base utilizes a central universal locking mechanism to capture the tibial insert. The ATTUNE Cemented Tibial Base, FB is manufactured from cast Co-Cr-Mo alloy conforming to ASTM F75. Additionally, the ATTUNE Cemented Tibial Base, FB utilizes a previously cleared Base Protector assembled with the device to minimize potential marring of the proximal bearing surface of the tibial base during impaction. After impaction is completed, the Base Protector is then removed and discarded prior to inserting the ATTUNE Fixed Bearing Insert. The ATTUNE CR Total Knee is designed to accommodate knee flexion to 150 degrees in those patients able to attain a high degree of knee flexion. The ATTUNE PS Total Knee is designed to accommodate knee flexion to 145 degrees in those patients able to attain a high degree of knee flexion.
More Information

No
The 510(k) summary describes a mechanical knee implant and its materials and testing, with no mention of AI or ML.

Yes
The device is described as a "Total Knee" replacement, used for patients with severely disabled knee joints due to various arthritic conditions or failed previous implants, indicating its purpose is to treat or alleviate a medical condition.

No

Explanation: The device described is a total knee replacement implant, specifically a tibial base. Its purpose is to replace a diseased or damaged knee joint component, which is a therapeutic function, not a diagnostic one. The "Intended Use / Indications for Use" section clearly states it's for patients with severely disabled joints "resulting from osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or a failed previous implant," indicating a treatment purpose.

No

The device description clearly describes a physical implant (tibial base) made of Co-Cr-Mo alloy, which is a hardware component, not software.

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

Here's why:

  • Intended Use/Indications for Use: The intended use describes the device as a component for total knee replacement surgery in patients with severely disabled knee joints. This is a surgical implant, not a diagnostic test performed on samples from the body.
  • Device Description: The description details the physical characteristics, materials, and function of a tibial base component for a knee replacement. It does not describe any process for analyzing biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological sample to diagnose a condition or provide information about a patient's health status.
  • Anatomical Site: The device is used directly within the knee joint, not for testing samples taken from the body.

In summary, the ATTUNE Cemented Tibial Base, Fixed Bearing is a surgical implant used to replace a damaged knee joint, which is a completely different category of medical device than an In Vitro Diagnostic.

Intended Use / Indications for Use

Candidates for total knee replacement include patients with a severely painful and/or severely disabled joint resulting from osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or a failed previous implant.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-Clinical Testing: Functional testing was conducted in compliance with FDA Guidance, Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses: Guidance for Industry and FDA, to verify that the implant performance is substantially equivalent to predicate devices for anticipated in-vivo loading via the following tests:
Fatigue Testing per ASTM F 1800, Standard Practice for Cyclic Testing of Metal Tibial Tray Components of Total Knee Joint Replacements
Intraoperative ROM simulation and pull-off testing with lipid and marrow
Surgeon validation
The proposed devices also meet the requirement of Bacterial endotoxin testing as specified in ANSI AAMI ST-72:2011.

Clinical Testing: Clinical testing was not necessary to determine substantial equivalence between the ATTUNE Cemented Tibial Base, FB and the predicate devices.

Conclusions: The subject Fixed Bearing ATTUNE Cemented Tibal Base, FB is substantially equivalent to the predicate Fixed Bearing ATTUNE Total Knee System Tibial Bases and Sigma Co-Cr Tibial Trays.

§ 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 of the
device | Total knee arthroplasty is intended to provide increased patient
mobility and reduced pain by replacing the damaged knee joint
articulation in patients where there is evidence of sufficient sound
bone to seat and support the components. Total knee replacement
may be considered for younger patients if, in the opinion of the
surgeon, an unequivocal indication for total knee replacement
outweighs the risks associated with the age of the patient, and if
limited demands regarding activity and knee joint loading can be
assured. This includes severely crippled patients with multiple joint
involvement for whom a gain in knee mobility may lead to an
expectation of significant improvement in the quality of their lives. |
| Indications for use | Candidates for total knee replacement include patients with a
severely painful and/or severely disabled joint resulting from
osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or a
failed previous implant. |

Summary of Technologies/ Substantial Equivalence Discussion:

The ATTUNE Cemented Tibial Base, FB provides a macro geometric feature and an optimized micro-blast finish which are both intended to aid in fixation of the tibial implant to the bone cement. The ATTUNE Cemented Tibial Base, FB is designed to enhance fixation by improving resistance (relative to the industry) to intra-operative factors which can result in a reduction in cement to implant bond.

The subject ATTUNE Cemented Tibial Base, FB has the same indications, intended used, materials, biocompatibility, packaging configurations, manufacturing methods, and sterilization methods as the previously cleared ATTUNE Cemented Tibial Base (K101433). The subject ATTUNE Cemented Tibial Base, FB is manufactured with undercut cement pockets similar to those previously cleared with the Sigma Co-Cr Trays (K032151).

The testing provided below was used to support equivalence to the predicate devices.
