The summary describes a system that uses patient-specific instruments based on imaging data to assist in surgical planning and execution. There is no mention of AI or ML in the intended use, device description, or performance studies. The system appears to be based on pre-operative planning and the creation of physical guides, not on adaptive or learning algorithms.
No
The device is a surgical instrument system used to assist in the positioning of knee replacement components and guide bone marking/cutting, not to treat a condition or disease directly.
No
The device is described as a surgical instrument to assist in intraoperative positioning and guiding of markings and cutting during total and unicompartmental knee replacement, not for diagnosing medical conditions.
No
The device description explicitly states that the system consists of both a software device (ZPSIP) and a hardware component (ZPSI).
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a "surgical instrument to assist in the positioning of Total Knee Replacement components intraoperatively and in guiding the marking of bone before cutting". This describes a surgical tool used during a procedure on a patient's body.
- Device Description: The description reinforces this by calling it a "modification to the predicate device... designed to assist a surgeon in the placement of total knee replacement components". It consists of software and hardware components used in the surgical setting.
- Lack of IVD Characteristics: An IVD device is used to examine specimens (like blood, urine, tissue) in vitro (outside the body) to provide information about a patient's health status, diagnose, monitor, or screen for diseases. This device does not perform any such analysis of biological specimens.
The device is a surgical planning and guidance system used directly on the patient during surgery, not for in vitro diagnostic testing.

§ 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.

Unicompartmental Knee Replacement
The Zimmer® Patient Specific Instruments System is intended to be used as a surgical instrument to assist in the positioning of Unicompartmental Knee Replacement components intra-operatively and in guiding the marking of bone before cutting and to guide cutting of the bone provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.
The Zimmer Patient Specific Instruments System is to be used with Zimmer Unicompartmental High Flex Knee System prostheses families only.
The Zimmer® Patient Specific Instruments are intended for single use only.
Functioning of the Device
The Zimmer® Patient Specific Instruments System 5.4 generates a pre-surgical plan based on MRI image data sets using the Zimmer Patient Specific Instruments Planner. The software device then is used pre-operatively by a qualified surgeon to inspect, fine-tune and approve the pre-surgical plan. Next, Zimmer Patient Specific Instruments are designed and manufactured based on the approved pre-surgical plan. Zimmer Patient Specific Instruments are patient specific templates which transfer the pre-operatively determined positioning of the chosen total knee replacement co the patient intra-operatively, assisting the surgeon in positioning and aligning the actual total knee replacement components by guiding and marking drill locations.

Dear Mr. Clemens:
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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must
