The summary describes a mechanical knee implant and its components, with no mention of software, algorithms, or AI/ML technologies. The performance studies focus on finite element analysis of the mechanical design.
Yes
The device is intended to replace damaged knee joint articulation to provide increased patient mobility and reduced pain, which are therapeutic outcomes.
No
The device is a medical implant (knee replacement system) used for treatment, not for diagnosing a condition. Its purpose is to replace damaged knee joint articulation.
No
The device description clearly states it is composed of physical components (femoral, tibial, and patellar components) intended for surgical implantation, indicating it is a hardware medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "provide increased patient mobility and reduced pain by replacing the damaged knee joint articulation." This describes a surgical implant used to treat a physical condition within the body.
- Device Description: The device is described as "unicompartmental femoral components, patellofemoral trochlear components, unicompartmental tibial components and patellar components." These are physical components designed to be implanted into the knee joint.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections. This device does not perform any such testing.
The DePuy Graduated Compartmental Knee (GCK) is a surgical implant used for knee replacement.
N/A
Intended Use / Indications for Use
The DePuy Graduated Compartmental Knee (GCK) is intended to provide increased patient mobility and reduced pain by replacing the damaged knee joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components.
The GCK is indicated for single or multi-compartmental knee replacement in skeletally mature individuals with osteoarthritis, posttraumatic arthritis of the tibiofemoral and/or patellofemoral articular surfaces or a history of gout or pseudogout. All GCK components are intended for CEMENTED USE ONLY.

Device Description
The DePuy GCK is composed of unicompartmental femoral components, patellofemoral trochlear components, unicompartmental tibial components and patellar components. These components may be used in various combinations to create: a single unicompartmental femorotibial replacement for either the medial or latcral side of the knee; two unicompartmental femorotibial replacements for both the medial and lateral sides of the knee; a patellofemoral replacement; a bicompartmental patcllofemorotibial replacement for the medial or lateral side of the knee; or a tricompartmental patellofemorotibial replacement for the medial and lateral sides of the knee.
The GCK unicompartmental femoral components are designed for individuals who require a higher than normal degree of flexion (up to 155°).
This submission describes design modifications to the previously cleared GCK unicompartmental femoral components and all polyethylene unicompartmental tibial components.

§ 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.

Summary of Technologies/Substantial Equivalence:
The modified GCK unicompartmental femoral and all polyethylene unicompartmental tibial components have the same indications and intended use, the same articulating geometry, the same sizes and are manufactured from the same materials as the previously cleared GCK unicompartmental femoral and all polyethylene unicompartmental tibial components.
Non-Clinical Testing:
Finite Element Analysis was performed to demonstrate the substantial equivalence of the modified GCK unicompartmental femoral components to the predicate Sigma Unicompartmental femoral components and other clinically successful designs.
Clinical Testing:
Clinical testing was not necessary to determine substantial equivalence between the subject modified GCK components and the predicate GCK components.

Dear Ms. Friddle:
We have reviewed your Section 510(k) premarket notification of intent to market the devices referenced above and have determined the devices are 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 devices, 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.
If your devices are classified (see above) into either class II (Special Controls) or class III (PMA), they may be subject to such additional controls. Existing major regulations affecting your devices can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your devices 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 devices comply with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set

forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your devices as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your devices to a legally marketed predicate device results in a classification for your devices and thus, permits your devices to proceed to the market.
If you desire specific advice for your devices on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
Sincerely vours.
