Intended Use

Indicated for use in total knee arthroplasty for reduction or relief of pain and/or improved knee function in skeletally mature patients with the following conditions: 1) noninflammatory degenerative joint disease including osteoarthritis, traumatic arthritis, or avascular necrosis; 2) inflammatory degenerative joint disease including rheumatoid arthritis; 3) correction of functional deformity; 4) revision procedures where other treatments or devices have failed; and 5) treatment of fractures that are unmanageable using other techniques. For cemented use only.

Device Description

The ADVANCE® Modular Tibial Component is part of the ADVANCE® Total Knee System, a total knee replacement system consisting of femoral, tibial, and patellar components. The ADVANCE® Modular Tibial Component is a modular component consisting of a tibial base, optional tibial augments, and optional stem extensions, all manufactured from titanium alloy. The base is offered both nonporous and porous coated, and features screw holes for optional fixation of the augments or for screw fixation. The base is designed for use with the ADVANCE® tibial inserts and the ADVANCE® femoral and patellar components cleared in previous premarket notifications. All components are intended to be used only with bone cement.

AI/ML (Artificial Intelligence / Machine Learning)

No
The document describes a mechanical implant (tibial component) and its materials and testing, with no mention of software, algorithms, or AI/ML capabilities.

Therapeutic

Yes
The device is indicated for the reduction or relief of pain and improved knee function, which are therapeutic outcomes. It is a total knee replacement system used to treat various degenerative joint diseases and correct functional deformities.

Diagnostic

The device is a knee implant (tibial component) used in total knee arthroplasty, which is a treatment for joint conditions, not a tool for diagnosing them.

SaMD (Software as a Medical Device)

The device description clearly states it is a modular tibial component made from titanium alloy, which is a physical hardware component for total knee replacement surgery.

IVD (In Vitro Diagnostic)

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

Here's why:

Intended Use: The intended use clearly describes a surgical implant for total knee arthroplasty to treat conditions affecting the knee joint. This is a therapeutic intervention performed in vivo (within the body).
Device Description: The device is a physical implant made of titanium alloy components designed to replace parts of the knee joint.
Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.

IVD devices are used to perform tests on samples taken from the body to provide diagnostic information. This device is a prosthetic implant used to restore function and reduce pain in a damaged joint.

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

Cyclic fatigue testing was performed according to ASTM F04.22.12. The porous and nonporous titanium tibial bases demonstrated to ability to withstand at least 2.2 x body weight at 10 million cycles under test conditions. Fatigue testing was performed according to ASTM F04.22.01. Results demonstrate the assembly's ability to withstand loads of up to 492 pounds for 1 million cycles. Axial distraction testing demonstrates adequate results under extreme conditions. Testing confirms the taper connection's integrity. Results from testing performed according to ASTM F-1044 demostrate that the static shear strength of the porous coating is adequate. Stereological evaluation of the porous coating demonstrates that the distance between particles and mean intercept length measured are in the range of 50 to 114 microns suggested as optimum for bone ingrowth by Bobyn, et al

Regulation Number and Section

§ 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.

Dear Ms. Tompkins:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Druq, and Cosmetic Act (Act). This decision is based on this device being equivalent only to similar devices labeled and intended to be fixed within bone with acrylic "bone cement." You may, therefore, market your device subject to the general controls provisions of the Act and the following limitations:

The thinnest tibial insert available is the nominal 1 . "10mm" sized insert, which has a minimum polyethylene thickness under the condyles of 6.0 mm.
1. This device may not be labeled or promoted for noncemented use.
1. All labeling for this device, including package label and labeling included within the package, must prominently state that the device is intended for cemented use only.
