Device Description
The femoral implants are provided in left and right-side versions and designed to replicate the natural anatomy of the femur. They are available in a single variant only - CR, with sizes ranging from 1 to 6. The femoral implants have a R.P design, which offers surgeon an option for patients where a more minimal anatomic design is preferred. The femoral implants are manufactured using cast CoCrMo alloy (ASTM F75). A monolayer of TiNbN coating (thickness: 3 to 7 microns) is applied to the femoral implants. The tibial baseplates are provided in left and right-side versions and designed to replicate the natural anatomy of the tibial baseplates are available in three variants – holed, pegged, and pegless, with sizes ranging from 0 to 6. The tibial baseplates are manufactured using cast CoCMo alloy (ASTM F75). A monolayer of TiNbN coating (thickness: 3 to 7 microns) is applied to the entire surface of the tibial baseplates.
More Information

No
The summary describes a knee replacement system focusing on materials, design, and mechanical testing, with no mention of AI/ML or related concepts like image processing, training/test sets, or performance metrics typically associated with AI/ML algorithms.

Yes

The device is a knee joint replacement system, which is a type of medical intervention designed to treat conditions like arthritis and replace damaged components, thereby providing a therapeutic effect by alleviating pain, restoring function, and improving quality of life for patients.

No

Explanation: The device is described as a knee implant system (femoral implants and tibial baseplates) used for surgical replacement in cases of arthritis or failed previous replacements. Its function is to replace damaged joint components, not to diagnose medical conditions.

No

The device description clearly details physical components (femoral implants, tibial baseplates) made of cast CoCrMo alloy with a TiNbN coating. The performance studies also focus on the mechanical properties and wear performance of these physical implants.

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: The description clearly states that this device is a knee implant (femoral implants and tibial baseplates). These are surgically implanted devices used to replace damaged knee joints.
  • Intended Use: The intended uses listed are for the surgical treatment of various knee conditions (arthritis, failed replacements, etc.). This involves direct intervention within the body, not testing of samples outside the body.
  • Lack of IVD Characteristics: The description does not mention any components or processes related to sample collection, analysis of biological samples, or providing diagnostic information based on such analysis.

Therefore, this device is a surgical implant, not an In Vitro Diagnostic.

The femoral implants are provided in left and right-side versions and designed to replicate the natural anatomy of the femur. They are

available in a single variant only - CR, with sizes ranging from 1 to 6. The femoral implants have a R.P design, which offers surgeon an option for patients where a more minimal anatomic design is preferred. The femoral implants are manufactured using cast CoCrMo alloy (ASTM F75). A monolayer of TiNbN coating (thickness: 3 to 7 microns) is applied to the femoral implants.

The tibial baseplates are provided in left and right-side versions and designed to replicate the natural anatomy of the tibial baseplates are available in three variants – holed, pegged, and pegless, with sizes ranging from 0 to 6. The tibial baseplates are manufactured using cast CoCMo alloy (ASTM F75). A monolayer of TiNbN coating (thickness: 3 to 7 microns) is applied to the entire surface of the tibial baseplates.

Intended Use/Indications for Use

21 CFR 807.92(a)(5)

The indications for use are:

A. Primary intervention of rheumatoid arthritis, post-traumatic arthritis, or degenerative arthritis

B. Failed osteotomy or unicompartmental replacements

  • C. Replacement of unsatisfactory cemented or press-fit knee components when sufficient bone stock exists
    D. The non-porous (uncoated, coated without Titanium, and uncoated with a TiNbN overcoat) components may only be used with cement

E. The porous coated (CoCr beads with Titanium) components may be used with or without cement

Indications for Use Comparison

The subject devices have intended use and indications for use as the predicate devices.

The subject devices have the same design, except the TiNbN coating, as the predicate devices. The dimensions and tolerances for the subject devices are same as the predicate devices. The subject devices use the same substrate material, same sterilization method, and same shelf life as the predicate devices.

Technological Comparison

The subject devices have the same intended use, same indications for use, and similar technological characteristics as the predicate devices. The only difference in the technological characteristics is the TiNbN coating on subject devices, whereas the predicate devices are uncoated.

The questions of safety and effectiveness regarding the TiNbN coating are whether it is biocompatible and whether it impacts (negatively) the articulating surface wear (femoral insert). These questions are also applicable to the predicate devices, therefore, the TiNbN coating does not raise different questions of safety and effectiveness.

The subject devices are manufactured using the same substrate material, cast CoCr (ASTM F75), as the predicate devices. The subject devices use the same manufacturing process (including manufacturing contact materials) as the predicate devices, except, the TiNbN coating step. DOT America, the company which performs the TiNbN coating step for the subject devices, has conducted exhaustive biocompatibility testing for the TiNbN coating on CoCr material (cytotoxicity, sensitization, irritation, acute systemic toxicity, and implantation). Therefore, based on the substrate material/manufacturing process equivalency between the subject and predicate devices and the biocompatibility testing data from DOT America for the subject devices with the TiNbN coating are considered biologically safe.

The wear performance of the subject and predicate devices was evaluated under Mode 3 conditions per ISO 14243-1. Based on the results of the wear testing, the subject devices have a superior wear resistance than the predicate devices under both Mode 1 and Mode 3 conditions.

Further, the following reference devices are TiNbN coated by DOT America:

Foundation, Foundation - PS, 3D-Knee (K122239) EVOLUTION NitrX Medial-Pivot Knee (K182251)

Therefore, based on the above discussion, the subject devices are considered substantially equivalent to the predicate devices.

devices, except that the subject devices have the TiNbN coating on the surface. However, the TiNbN coating does not have any effect on these tests and hence, the testing performed of the predicate devices can be leveraged for the subject devices. o Tibial Baseplate Fatigue Test o Tibial Baseplate - Tibial Insert Locking Mechanism

o Range of Motion Analysis

The test reports, statements, and justification for using existing are attached to this section.

N/A

A significant number of tests were performed by DOT in support of ascertaining the safety and efficacy of the TiNbN coating. The wear performance of the subject and predicate devices was evaluated under Mode 3 conditions per ISO 14243-1. Based on the results of the wear testing, the subject devices have a superior wear resistance than the predicate devices under both Mode 1 and Mode 3 conditions. The tibial baseplate fatigue test, tibial insert locking mechanism test, and range of motion analysis for the predicate devices are leveraged for the subject devices. Based on the nondinical testing data, it can be concluded that the subject devices are at least as safe and effective as the predicate devices.
