Intended Use

The VERASENSE is indicated for any medical condition in which primary or revision Total Knee Arthroplasty (TKA) would be indicated. For use as a tool for adjustment of the implant to reduce instability from flexion gap asymmetry. The VERASENSE is sterile, for single patient use.

Device Story

VERASENSE is an intelligent disposable tibial insert for intraoperative knee balancing during TKA. It uses capacitive sensors to measure dynamic loads in medial and lateral knee compartments. Data is transmitted wirelessly to a LinkStation MINI or Evaluation Kit running the VERASENSE Software Application (VSA). The VSA displays real-time graphical and numerical load data and center of load (COL) location to the surgeon. Used in hospital operating rooms by surgeons to guide implant adjustment, reducing flexion gap asymmetry and improving joint stability. The device is sterile, single-use, and implant-system specific.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by bench testing, including biocompatibility (ISO 10993-1), electrical safety, EMC, software verification/validation, and performance testing (usability, sterilization, packaging, shelf life).

Technological Characteristics

Disposable tibial insert with capacitive sensors. Materials: PEEK (VITREX 381G) and stainless steel. Power: Two 3V Lithium batteries (parallel). Wireless: 2402–2480 MHz Bluetooth. Sterilization: Ethylene Oxide (10^-6 SAL). Software: VSA running on Windows 10 tablet. Connectivity: Bluetooth/USB. Electrical safety: AAMI ANSI ES60601-1. EMC: IEC 60601-1-2.

Indications for Use

Indicated for patients undergoing primary or revision Total Knee Arthroplasty (TKA) requiring adjustment of the femoral implant to reduce instability from flexion gap asymmetry.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

#### III. PREDICATE DEVICE

VERASENSE Knee System, K150372

#### IV. DEVICE DESCRIPTION

VERASENSE provides a means to dynamically balance the knee during primary or revision Total Knee Arthroplasty (TKA).

The VERASENSE consists of a knee sensor device and the following required accessories: LinkStation MINI or LinkStation Evaluation Kit and VERASENSE Software Application (VSA). The required accessories are intended to support the performance of the VERASENSE parent device. The LinkStation MINI / LinkStation MINI Evaluation Kit is capable of running the VSA and communicating wirelessly with the VERASENSE from outside the sterile field in the operating room. Individual VERASENSE devices are packaged sterile,

The symbol is made up of three curved shapes, two in blue and one in gray, arranged in a triangular formation. The word "ORTHOSENSOR" is written in a simple, sans-serif font, with the letters in gray.

for single patient use with a Shim Set for thickness adjustments. The required accessories are not packaged sterile and are reusable.

The VERASENSE device is an intelligent disposable tibial insert that measures dynamic loads in the medial and lateral compartments of the knee and wirelessly transmits the measured load data to the LinkStation MINI or LinkStation MINI Evaluation Kit. The VSA provides the surgeon with a graphical and numerical presentation of the loads in both the medial and lateral compartments of the knee. The VSA also provides location of the center of load (COL) from the femoral to the tibial component in each of the medial and lateral compartments for reference only.

VERASENSE devices are implant system specific due to variations in implant design. VERASENSE is compatible with the following implant systems:

- VERASENSE for Biomet Vanguard ●
- VERASENSE for Stryker Triathlon ●
- VERASENSE for Zimmer NexGen ●
- VERASENSE for Smith & Nephew Legion ●
- VERASENSE for Smith & Nephew Journey II ●
- . VERASENSE for Zimmer Biomet Persona

#### INDICATIONS FOR USE V.

The VERASENSE is indicated for any medical condition in which primary or revision Total Knee Arthroplasty (TKA) would be indicated.

For use as a tool for adjustment of the femoral knee implant to reduce instability from flexion gap asymmetry. The VERASENSE is sterile, for single patient use.

### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE VI. PREDICATE DEVICE

At a high level, the subject and predicate devices are based on the following same technological elements:

- Capacitive sensors on the device measure the pressure exerted by the ● femoral component of the implant on the sensor.
- Required accessories intended to support the performance of the VERASENSE parent device are the LinkStation MINI or LinkStation MINI Evaluation Kit and VERASENSE Software Application (VSA)
- Patient contacting material of the top and bottom housings

- Articular surface is on shims, detached from the electronics ●
- Electronics module is reversible ●
- Patient contacting shim material changed to PolyEtherEtherKetone ● (PEEK) and stainless steel
- . Sensor wireless communication frequency changed to 2402 – 2480 MHz Bluetooth
- . New wireless connection mode for the LinkStation MINI / LinkStation MINI Evaluation Kit via tablet component integrated Bluetooth
- New version of the VSA with the addition of the VERASENSE for Zimmer Biomet Persona to the scope of the software application
