Intended Use

When used with the AGC and Maxim Knee Systems, the indications for use of the Titanium Femoral Component include 1)painful and disabled knee joint resulting from osteoarthritis, rheumatiod arthritis, or traumatic arthritis where one or more compartments are involved, 2)failure of a previous joint replacement procedure. 3)correction of varus, valgus or post traumatic deformity, and 4)correction or revision of unsuccessful osteotomy or arthrodesis. Device designed for use in patients with metal sensitivity. Standard surgical and rehabilitative procedures are indicated with this device. This device is a single use implant for use with bone cement.

Device Story

Titanium Femoral Component designed as alternative to Co-Cr-Mo knee prostheses for patients with metal sensitivity. Implanted during knee arthroplasty; requires bone cement fixation. Available in multiple sizes for AGC and Maxim Knee Systems. N-ion implanted surface treatment reduces wear of component and UHMWPE articulating surfaces. Used by orthopedic surgeons in clinical settings to restore joint function and correct deformities.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and material comparison to predicate devices.

Technological Characteristics

Titanium alloy femoral component; N-ion implanted surface (Biomet spec 1.4) to reduce wear. Designed for cemented fixation only. Single-use implant.

Indications for Use

Indicated for patients with painful/disabled knee joints due to osteoarthritis, rheumatoid arthritis, or traumatic arthritis; failure of previous joint replacement; correction of varus, valgus, or post-traumatic deformity; or revision of unsuccessful osteotomy/arthrodesis. Designed for patients with metal sensitivity. For use with bone cement.

Regulatory Classification

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).

• AGC 2000 Total Knee Prosthesis (Biomet, Inc.)
• MG II Total Knee (Zimmer, Inc.)
• Kinemax Plus Total Knee System (Howmedia, Inc.)

# SUMMARY OF SAFETY AND EFFECTIVENESS

Sponsor: Biomet, Inc. Airport Industrial Park P.O. Box 587 Warsaw, IN 46581-0587

Device: Titanium Femoral Component

Classification Name: Knee Joint Patellofemorotibial Polymer/Metal/Polymer Semi-Constrained Cemented Prosthesis (CFR 888.3560)

- Intended Use: When used with the AGC and Maxim Knee Systems, the indications for use of the Titanium Femoral Component include 1)painful and disabled knee joint resulting from osteoarthritis, rheumatiod arthritis, or traumatic arthritis where one or more compartments are involved, 2)failure of a previous joint replacement procedure. 3)correction of varus, valgus or post traumatic deformity, and 4)correction or revision of unsuccessful osteotomy or arthrodesis.
Device designed for use in patients with metal sensitivity.

Standard surgical and rehabilitative procedures are indicated with this device.

This device is a single use implant for use with bone cement

- Device Description: The femoral components of the AGC and Maxim Knee Systems are identical to their Co-Cr-Mo predecessors with the exception of the material used in manufacturing and a limited component availability. The AGC titanium component is available in primary universal components of five different sizes. The Maxim titanium component is available in five sizes of the primary universal component and five sizes of the revision universal component.
The titanium components are all N ion implanted, to Biomet engineering specification 1.4, in order to reduce the wear of both the titanium femoral component and the ultrahigh molecular weight polyethylene (UHMWPE).

- Potential Risks: The potential risks associated with this device are the same as with any joint replacement device. These include, but are not limited to:
Reaction to the bone cement Blood vessel damage Deformity of the joint Cardiovascular disorders Fracture of the cement Implant loosening/migrating Fracture of the component Nerve damage

Soft tissue imbalance Delaved wound healing Metal sensitivity

Bone fracture Infection Hematoma Dislocation Excessive wear

Dear Mr. McClure:

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, Drug, 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 and Inconably therefore, market your device subject to the general controls provisions of the Act and the following limitations:

- This device may not be labeled or promoted for non-1. cemented use.
- All labeling for this device, including package label and 2. labeling included within the package, must prominently state that the device is intended for cemented use only.
- Any non-cemented fixation of this device is considered 3. investigational and may only be investigated as a significant risk device in accordance with the investigational device exemption (IDE) regulation under 21 CFR, Part 812. All users of the device for noncemented fixation must receive approval from their respective institutional review boards (IRBs) and the Food and Druq Administration (FDA) to conduct the investiqation.
