The summary describes a mechanical knee replacement system and its components, focusing on materials, design features, and wear testing. There is no mention of software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is a total knee replacement system intended to treat severe joint pain and disability, which aligns with the definition of a therapeutic device.
No
The device is a total knee replacement system, intended to replace damaged knee joints. It is a treatment device, not one that gathers or analyzes data to diagnose a condition.
No
The device description clearly details physical components made of materials like Co-Cr-Mo alloy and ultra high molecular weight polyethylene, indicating it is a hardware medical device.
Based on the provided text, the DePuy Attune™ Knee System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is clearly stated as a "total knee replacement system" for treating joint conditions like osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or failed previous implants. This is a surgical implant, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details the physical components of the knee implant (femoral components, tibial insert, tibial bases, patellae) and the materials they are made from. This aligns with a medical device intended for implantation.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
Therefore, the DePuy Attune™ Knee System is a surgical implant, not an In Vitro Diagnostic device.

Device Description
The Attune™ femoral components are available in a cruciate retaining (CR) version. The CR femoral components have an asymmetric trochlear groove and are available in sizes 1-10 in right and left options. Sizes 3-6 are available in standard and narrow options. The fixation surface is textured. It incorporates two lugs (pegs) to provide additional stability and recessed cement pockets for enhanced cement fixation. The Attune Femoral Components are manufactured from cast Co-Cr-Mo alloy conforming to ASTM F75.
The Attune fixed bearing CR tibial insert is designed with a topography that, in the sagittal view, consists of multiple radii. The sagittal anterior radii are tight to aid in anterior constraint while the posterior radius is larger to allow rollback. The Attune design allows for the retained posterior cruciate ligament and/or balanced posterior capsule to assist in appropriate rollback of the femur. The design offers minimal but appropriate constraint in the posterior direction for maximal rollback and full range of motion. The Attune fixed bearing CR tibial inserts are available in sizes 1-10 and in thicknesses of 5, 6, 7, 8, 10, 12, 14, 16, and 18mm. The inserts are manufactured from AOX ultra high molecular weight polvethvlene conforming to ASTM F648. The Attune tibial bases are available in sizes 1-10. The Attune tibial base fixation surface is textured. It incorporates a stem and keel to provide additional stability and recessed cement pockets for enhanced cement fixation. The Attune tibial base utilizes a central universal locking mechanism to capture the tibial insert. The Attune tibial bases are manufactured from cast Co-Cr-Mo alloy conforming to ASTM F75. The Attune patellae are available in sizes 29, 32, 35, 38, and 41mm. The fixation surface incorporates 3 pegs to provide stability and recessed cement pockets for enhanced cement fixation. The patella components are manufactured from AOX ultra high molecular weight polyethylene conforming to ASTM F648. The Attune Knee System is designed to accommodate knee flexion to 150 degrees in those patients able to attain a high degree of knee flexion. Total knee replacement 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. The Attune Knee System is intended to accommodate knee flexion to 150 degrees in those patients able to attain a high degree of knee flexion.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Testing:
Physical and mechanical testing was conducted on the AOX ultra high molecular weight polyethylene in accordance with ASTM F648. This testing includes the following characterization: Yield Strength, Ultimate Tensile Strength, Elongation to Break, Young's Modulus, Impact Resistance, Fatigue Crack Propagation, Compression Modulus, Crystallinity (Differential Scanning Calorimetry), Peak Melting Temperature (Differential Scanning Calorimetry), Ash Content, Gravimetric Swell Ratio, Oxidation Index (Fourier Transform Infrared Spectroscopy).
The biocompatibility test plan developed to evaluate the AOX material was in accordance with the ISO draft Guidance on the Conduct of Biological Evaluation within a Risk Management Process (ISO/DTR 15499). The test plan included methods that address FDA guidance documents and specifically ISO 10993 parts 3-6, 10, and 11. In addition to the ISO 10993 tests, other USP tests to characterize leachable components were conducted.
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 would be substantially equivalent to predicate devices for anticipated in vivo loading via various constraint and fatigue tests.
In vitro knee simulator wear testing demonstrated that the Attune CR femoral component/tibial insert couple exhibited a significant volumetric wear reduction as compared to a control total knee system. The results of in-vitro wear simulation testing have not been proven to quantitatively predict clinical wear performance.
Attune CR Fixed Bearing Wear Claim Information:
DePuy manufactured both the Attune CR fixed bearing total knee (subject) and the Sigma CR Curved fixed bearing total knee (control) in this wear test. All Attune CR products tested were size 5 while all Sigma CR products tested were size 3. The actual insert thicknesses used were 6mm for the Attune CR tibial AOX polyethylene insert (composite insert and base thickness of 10mm) and actual insert thickness of 8mm for the Sigma Curved tibial XLK polyethylene insert (composite insert and tray thickness of 10mm). The Attune CR inserts were manufactured from antioxidant stabilized compression molded GUR 1020 UHMWPE. The Sigma Curved inserts were manufactured from crosslinked (50 kGy) compression molded GUR 1020 UHMWPE. The Attune CR CoCr femoral and fixed bearing tibial base components were not sterilized for the tests. The Attune CR AOX fixed bearing inserts were sterilized and crosslinked via gamma radiation (75.0 - 90.0 kGy) and packaging (vacuum in foil pouch). The Sigma CR CoCr femoral and fixed bearing tibial tray components were sterilized via gamma radiation (28.5 kGy). The Sigma Curved XLK fixed bearing inserts were sterilized via gas plasma sterilization. Wear testing was performed via AMTI multi-axial displacement controlled knee joint simulator per ISO 14243-3 loads combined with published physiological kinematics at a frequency of 1 Hz for 5 million cycles utilizing a lubricant of 25% bovine serum with an average protein content of 16.5 mg/ml. The Attune mean gravimetric wear rate was 3.6 ± 0.3 mg/million cycles while the Sigma mean gravimetric wear rate was 7.12 ± 1.2 mg/million cycles. Thus the Attune CR fixed bearing total knee system exhibits 50% less overall mean gravimetric wear than the previously cleared DePuy Sigma Curved fixed bearing total knee system for the same composite thickness. The wear debris was analyzed at 1, 3, and 5 million cycles via LALLS and SEM analysis. The Attune AOX mean particle diameter (LALLS volume analysis), aspect ratio (SEM), roundness (SEM), and perimeter (SEM) measured 118,8um. 2.10, 0.56, and 3.56um while Sigma XLK measured 64.4um, 2.06, 0.56, and 3.17um respectively. No significant difference between the AOX and XLK debris samples was found. Wear testing to 10 million cycles was also performed utilizing the thinnest available insert thicknesses, actual insert thickness of 5mm for the Attune CR tibial AOX polyethylene insert (composite insert and base thickness of 9mm) and actual insert thickness of 6mm for the Sigma Curved tibial XLK polyethylene insert (composite insert and tray thickness of 8mm). The Attune mean gravimetric wear rate for the thin inserts was 5.4 ± 0.5 mg/million cycles while the Sigma mean gravimetric wear rate for the thin insert was 5.7 ± 0.7 mg/million cycles with no statistical difference in wear rate. In vitro knee wear simulator tests have not been shown to quantitatively predict clinical wear performance.
