Intended Use

The TruMatch™ Patient Specific Instruments are intended to be used as patient-specific surgical instrumentation to assist in the positioning of a joint replacement component intra-operatively and in guiding the marking of bone before cutting. The anatomical landmarks necessary for the creation of the TruMatch™ Patient Specific Instruments must be present and identifiable on CT. The TruMatch™ Patient Specific Instruments are intended for use with Sigma® Total Knee Implants and Attune™ Total Knee Implants and their cleared indications for use. The TruMatch™ Patient Specific Instruments are intended for single use only.

Device Story

TruMatch™ Patient Specific Instruments are custom-manufactured surgical guides created from patient CT imaging data. These instruments assist surgeons during total knee arthroplasty by guiding bone marking and positioning of Sigma® or Attune™ knee implants. The process involves converting patient CT data into patient-specific physical guides used intra-operatively to improve surgical accuracy. The device is intended for single use. Surgeons use these guides to align implants according to the pre-operative plan derived from the patient's anatomy. The system aims to enhance the precision of bone cuts and component placement, potentially improving surgical outcomes for patients undergoing knee replacement.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including dimensional stability tests, cadaver accuracy studies, and design/software repeatability and validation studies.

Technological Characteristics

Patient-specific surgical instruments manufactured from patient CT data. Designed for single-use. Technical validation includes dimensional stability, design process repeatability, and software verification. Compatible with Sigma and Attune knee implant systems.

Indications for Use

Indicated for patients undergoing total knee arthroplasty requiring joint replacement components; used to assist in intra-operative positioning and bone marking. Requires identifiable anatomical landmarks on CT scans. Contraindicated if landmarks are not present on CT.

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).
