## Intended Use

The Balanced Knee System Revision Offset Tibia is intended for use with the Balanced Knee System in total knee arthroplasty procedures, previously failed surgical attempts where bone loss may require the use of augments or stem extensions, or difficult primary surgical cases where a long extension stem is necessary.

## Device Story

Modular orthopedic implant system for primary and revision knee arthroplasty; components include offset tibial tray, adapter, screw, and stem. Machined from titanium alloy (Ti-6Al-4V ELI). Used by orthopedic surgeons in clinical settings to address bone loss or complex primary cases requiring long extension stems. Provides structural support for knee joint reconstruction. Mechanical performance validated via fatigue and static load testing.

## Clinical Evidence

Bench testing only. No clinical data provided. Mechanical validation included tibial tray fatigue testing and progressive static load testing to ensure the device withstands anticipated in vivo loading and cycling.

## Technological Characteristics

Modular tibial tray system; material: titanium alloy (Ti-6Al-4V ELI); semi-constrained cemented prosthesis; design includes offset tray, adapter, screw, and stem components.

## Regulatory 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).

Dear Mr. Haueter:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
