Intended Use
MyKnee Cutting Blocks are intended to be used as anatomical cutting blocks specific for a single patient anatomy to assist in the positioning of total knee replacement components intraoperatively and in guiding the marking of hone before cutting. MyKnee Cutting Blocks are intended for use with GMK Total Knee System and its cleared indications for use. MyKnee Cutting Blocks are intended for single use only.
Device Description
MyKnee Cutting Blocks are designed and manufactured from patient imaging data so that the cutting blocks match the patient's anatomy. The MvKnee Cutting blocks for the patient are used with Medacta's existing GMK Total Knee System.
More Information

No
The description focuses on patient-specific design based on imaging data and validated software tools, but there is no mention of AI or ML algorithms being used in the design or manufacturing process.

No

Explanation: The device is a cutting block used to assist in the positioning of knee replacement components and guide marking before cutting. It is an intraoperative tool and not a device that directly treats a medical condition.

No

The device is described as an anatomical cutting block used intraoperatively to assist in the positioning of total knee replacement components and guide bone marking. It does not perform any diagnostic function of identifying a disease or condition.

No

The device description explicitly states that the device is "designed and manufactured from patient imaging data" and refers to "cutting blocks," which are physical objects used intraoperatively. The performance studies also include testing on physical properties like biocompatibility, dimensional accuracy, mechanical testing, and cleanliness, indicating a hardware component.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to assist in the positioning of total knee replacement components intraoperatively and guide bone marking before cutting. This is a surgical aid used during a procedure on the patient's body.
  • Device Description: The device is a physical cutting block designed to match a patient's anatomy for surgical guidance.
  • Lack of In Vitro Activity: IVD devices are intended for use in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis on biological specimens.

The device is a surgical planning and guidance tool used directly on the patient during surgery, not an in vitro diagnostic test.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.

(a)
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).(b)
Classification. Class II.

Product Description:

MyKnee Cutting Blocks are designed and manufactured from patient imaging data so that the cutting blocks match the patient's anatomy. The MvKnee Cutting blocks for the patient are used with Medacta's existing GMK Total Knee System.

Intended Use and Indications for Use:

MyKnee Cutting Blocks are intended to be used as anatomical cutting blocks specific for a single patient anatomy to assist in the positioning of total knee replacement components intraoperatively and in guiding the marking of bone before cutting.

MyKnee Cutting Blocks are intended for use with GMK Total Knee System and its cleared indications for use.

MyKnee Cutting Blocks are intended for single use only.

Comparison to Predicate Devices

MyKnee Cutting Blocks have the same intended use as the Smith & Nephew's Patient Matched Cutting Blocks except for use with the Medacta GMK system instead of the Smith & Nephew's cleared total knee systems. Both are manufactured from the same material using the type of process where the cutting blocks are matched to the patient's anatomy using data from patient imaging files.

MyKnee Cutting Blocks are also substantially equivalent to the standard distal femoral and proximal tibial cutting blocks used in conjunction with the GMK Total Knee system cleared under K090988. MyKnee Cutting Blocks are used with the GMK Total Knee System for the indications for use for which the GMK Total Knee System is cleared.

Performance Testing

No performance standards applicable to this device have been adopted under Section 514 of the Food, Drug and Cosmetic Act. Performance testing of the MyKnee Cutting Blocks was conducted in accordance with various international standards and FDA quidance documents.

Non-clinical testing included biocompatibility testing to ISO 10993 applicable to external communicating devices with limited (
