Intended Use
The Columbus (CR) Total Knee System is intended for use in reconstruction of the diseased knee joint caused by osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, the need to revise failed arthroplasties or osteotomies where pain, deformity or dysfunction persists, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture. The Columbus Knee is designed for use with bone cement.
Device Description
The cemented Columbus (CR) Total Knee System is available with one femoral design, the Cruciate Retaining (CR) which retains the ligament (PCL) during implantation. The design of the femoral component and tibial plateau (tray) are manufactured from CoCrMo. In addition to the standard insert design, a "deep dish" design is available for patients that may need more stability than the standard design. The "deep dish" insert has a slightly smaller range of motion to provide more restraint than the standard insert design. The gliding surfaces (inserts) and patellas are manufactured from UHMWPE.
More Information

Not Found

No
The summary describes a traditional knee implant system made of standard materials and does not mention any computational or software components that would suggest the use of AI or ML.

Yes
The device is described as a "Total Knee System" intended for reconstruction of the diseased knee joint, which directly addresses a health condition.

No

Explanation: The provided text describes a "Columbus (CR) Total Knee System," which is an orthopedic implant for joint reconstruction. Its intended use is to replace diseased knee joints and revise failed arthroplasties. There is no mention of the device being used to diagnose conditions, process images, or provide diagnostic information.

No

The device description clearly states it is a "Total Knee System" with components manufactured from CoCrMo and UHMWPE, indicating it is a physical implant, not software.

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 Columbus (CR) Total Knee System is for the reconstruction of the diseased knee joint. This is a surgical implant used in vivo (within the body).
  • Device Description: The description details the materials and design of a knee prosthesis, which is a physical implant.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.

IVD devices are used in vitro (outside the body) to analyze samples. This device is a surgical implant used in vivo.

§ 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.

Dear Ms. Kilroy:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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 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 device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4659. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
