## Intended Use

The ACHIEVE PARTIAL KNEE SYSTEM is intended for unicompartmental knee arthroplasty to treat one or more of the following conditions: - Moderately disabling joint disease of the knee resulting from painful osteo or post traumatic arthritis. - Revision of previous unsuccessful surgical procedures, including prior unicompartmental knee arthroplasty. - As an alternative to tibial osteotomy in patients with unicompartmental osteoarthritis.

## Device Story

ACHIEVE Partial Knee System is a unicompartmental knee prosthesis for arthroplasty; treats painful osteoarthritis, post-traumatic arthritis, or failed prior surgeries. System comprises metal tibial tray (titanium alloy), polyethylene tibial insert (Cross-linked, Vitamin E UHMWPE), and metal femoral component (titanium alloy or cobalt-chromium). Components with engineered porous surfaces allow cementless or cemented fixation; non-porous components require cement. Used by orthopedic surgeons in clinical settings. Provides mechanical replacement of knee joint surfaces to restore function and reduce pain. Substantial equivalence established via non-clinical bench testing; no clinical data required.

## Clinical Evidence

No clinical data. Substantial equivalence demonstrated through non-clinical bench testing, including range of motion (ASTM F2083), femoral fatigue (modified ASTM F3210), tibial tray fatigue (modified ASTM F3140), component interlock strength, wear resistance (ISO 14243-3), and contact stress testing. Porous structures validated per ASTM F1044, F1147, F1160, F1978, and F1854.

## Technological Characteristics

Materials: Titanium alloy, cobalt-chromium, Cross-linked Vitamin E UHMWPE. Fixation: Cemented or cementless (porous-coated). Standards: ASTM F2083 (RoM), ASTM F3210/F3140 (fatigue), ISO 14243-3 (wear), ISO 10993-1 (biocompatibility), ISO 11607-1/2 (packaging), ISO 11137-1/2 (sterilization). Porous structure testing per ASTM F1044, F1147, F1160, F1978, F1854. Sterilization: VDmax method (SAL 10^-6).

## Regulatory Identification

A knee joint femorotibial (uni-compartmental) metal/polymer porous-coated uncemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surface. It has no linkage across-the-joint. This generic type of device is designed to achieve biological fixation to bone without the use of bone cement. This identification includes fixed-bearing knee prostheses where the ultra-high molecular weight polyethylene tibial bearing is rigidly secured to the metal tibial baseplate.

## Special Controls

*Classification.* Class II (special controls). The special control is FDA's guidance: “Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.” See § 888.1 for the availability of this guidance.

# Device Description:

The ACHIEVE™ PARTIAL KNEE SYSTEM is a knee joint femorotibial (unicompartmental) prosthesis that is intended for cementless or cemented fixation.

The implant system consists of individually packaged implants: a metal tibial tray (titanium alloy), a polyethylene tibial insert, and a metal femoral component (titanium alloy or cobalt-chromium). All tibial inserts are composed of a Cross-linked, Vitamin E Ultra High Molecular Weight Polyethylene (Cross-Linked, VE UHMWPE).

#### Indications for Use:

The ACHIEVE PARTIAL KNEE SYSTEM is intended for unicompartmental knee arthroplasty to treat one or more of the following conditions:

- . Moderately disabling joint disease of the knee resulting from painful osteo or post traumatic arthritis.
- Revision of previous unsuccessful surgical procedures, including prior unicompartmental knee arthroplasty.
- . As an alternative to tibial osteotomy in patients with unicompartmental osteoarthritis.

#### Fixation Methods

Tibial trays and femoral components with engineered porous surfaces are intended for cemented or cementless use.

Tibial trays and femoral components without engineered porous surfaces are intended for cemented use only.

#### Summary of Technologies/Substantial Equivalence:

The implant and associated instruments within the ACHIEVE™ Partial Knee System are substantially equivalent to the predicate device in terms of its intended use and indications, material, design, sizes, and mechanical properties. Differences between the subject device system and the predicate device system do not raise different questions of safety and effectiveness.

#### Non-Clinical Testing:

The ACHIEVE™ Partial Knee System underwent non-clinical testing and analyses to support a determination of substantial equivalence to the predicate device. The following were completed:

{6}------------------------------------------------

Image /page/6/Picture/1 description: The image shows the logo for Ignite Orthomotion. The logo features a green flame-like graphic on the left, followed by the word "IGNITE" in gray, all caps, and a sans-serif font. Below "IGNITE" is the word "ORTHOMOTION," also in gray, all caps, and a sans-serif font, but smaller than "IGNITE."

# Predicate Comparison Evaluation

A detailed comparison of key technologies and feature dimensions was made between the subject device and predicate devices. The comparison concluded the subject device key technologies and feature dimensions are substantially equivalent to that of the predicate devices.

# Range of Motion (RoM) Evaluation

An evaluation was conducted to ensure the RoM of the worst-case subject device components meet established specifications per ASTM F2083. The RoM targets were met.

# Femoral Fatigue Testing

Femoral fatigue testing was performed to 10 Mc per modified ASTM F3210. The acceptance criteria were met.

#### Tibial Tray Fatigue Testing

Tibial Tray fatigue testing was performed to 10 Mc per modified ASTM F3140. The acceptance criteria were met.

#### Component Interlock Strength Testing

To characterize the strength of attachment between the Tibial Tray and Tibial Bearing, static AP and ML shear testing and static tensile pull-off testing were performed. The acceptance criteria were met.

#### Evaluation of Wear Resistance

Wear testing was performed per ISO 14243-3. The wear rate of the subject device does not represent a new worst-case when compared directly to a predicate device.

#### Tibial-Femoral Contact Area/Contact Stress Testing

The contact surface areas and contact stresses were determined experimentally and an engineering justification demonstrated that the subject device does not represent a new worst-case for tibialfemoral contact area/contact stress when compared to the predicate devices.

{7}------------------------------------------------

Image /page/7/Picture/1 description: The image shows the logo for Ignite Orthomotion. The logo features a green flame-like graphic on the left side, followed by the word "IGNITE" in gray, and the word "ORTHOMOTION" in a smaller font size below the word "IGNITE". The logo is simple and modern, and the use of green and gray gives it a clean and professional look.

# Characterization of VE-UHMWPE

The Vitamin E Ultra High Molecular Weight Polyethylene (Cross-linked, VE UHMWPE) material used for the Tibial Bearings of the ACHIEVE™ Partial Knee System was fully characterized per FDA Guidance, "Characterization of Ultrahigh Molecular Weight Polyethylene (UHMWPE) Used in Orthopedic Devices-Guidance for Industry and Food and Drug Administration Staff."

#### Characterization of Titanium Articular Surface Coatings

The wear properties of the Titanium Nitride (TiN) coating of the articular surface were characterized and found to be substantially equivalent to an uncoated cobalt-chrome alloy (CoCrMo) when articulating with a UHMWPE bearing couple. An engineering justification demonstrated that the subject device does not represent a new worst-case for wear resistance, abrasion-resistance and surface hardness of the articulating surfaces when compared to the predicate device, which is made from CoCrMo.

#### Biocompatibility Assessments

The contact classification for the subject devices is Implant, Bone/Tissue with permanent contact (>30 days). A Biocompatibility Assessment was completed and provided per ISO 10993-1 and FDA Guidance Document Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process. The devices were found to be biocompatible.

#### Porous Structure Characterization

The porous structure used for the subject device was evaluated per ASTM F1044 (Static Shear Strength), ASTM F1147 (Static Tensile Strength), ASTM F1160 (Shear Fatigue), ASTM F1978 (Abrasion Resistance), and ASTM F1854 (Stereological Evaluation). The engineered porous structure meets the recommendations of the Class II Special Controls Guidance Document: Knee Joint Patellfemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.

#### Shelf-Life Evaluation

A shelf-life evaluation per ISO 11607-1 and ISO 11607-2 was completed on the packaging materials that make up the sterile barrier. A five-year shelf life was established based on the resultant data.

Image /page/8/Picture/1 description: The image shows the logo for Ignite Orthomotion. The logo features a green flame-like graphic on the left, followed by the word "IGNITE" in gray, uppercase letters. Below "IGNITE" is the word "ORTHOMOTION" in smaller, gray, uppercase letters. The logo is clean and modern, with a focus on the company name and a visual element that suggests energy or movement.

# Sterilization Validation

Sterilization validation was completed using the VDmax method specified in ISO 11137-1 and ISO 11137-2. The Sterility Assurance Level (SAL) was found to be 10-6.

### Clinical Testing:

Clinical testing was not necessary to demonstrate substantial equivalence of the ACHIEVE™ Partial Knee System to the predicate devices.

#### Conclusion:

A comparison of the subject and predicate devices, including comparison of the intended use, technological characteristics, and non-clinical testing results has demonstrated that the subject device has a safety and effectiveness profile equivalent to that of the predicate device. Thus, the subject device is substantially equivalent to the predicate device.
