## Intended Use

Smith & Nephew's VISIONAIRE Patient Matched Cutting Blocks are intended to be used as patient-specific surgical instrumentation to assist in the positioning of total knee replacement components intra-operatively and in guiding the marking of bone before cutting provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans. The Smith & Nephew VISIONAIRE Patient Matched Cutting Blocks are intended for use with the following existing Smith & Nephew, Inc. Knee Systems and their cleared indications for use: - Genesis II Knee System - Legion Knee System - Journey BCS Knee System - Journey II Knee System The Smith & Nephew VISIONAIRE Patient Matched Cutting Blocks are intended for single use only.

## Device Story

VISIONAIRE Patient Matched Cutting Blocks are patient-specific surgical instruments used during total knee replacement. The device utilizes patient imaging data (MRI, X-ray) and VISIONAIRE software to design and manufacture custom blocks that assist surgeons in positioning implants and marking bone intra-operatively. The system is used in clinical settings by surgeons. The software process includes an X-ray measurement tool to facilitate design. The blocks are single-use. By providing patient-specific alignment guides, the device aims to improve the accuracy of implant positioning and bone preparation, potentially enhancing surgical outcomes for patients undergoing knee arthroplasty.

## Clinical Evidence

No clinical data was needed to support the safety and effectiveness of the subject device. Bench testing was limited to software verification and validation in accordance with FDA guidance.

## Technological Characteristics

Patient-specific cutting blocks designed via VISIONAIRE software using MRI/X-ray inputs. No changes to mechanical design, materials, or manufacturing processes compared to the predicate. Software components are classified as a 'major' level of concern. Connectivity involves processing patient imaging data for custom design.

## 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).
