No
The summary describes a mechanical knee implant system and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is a total knee prosthesis intended to replace damaged knee joints and alleviate symptoms like pain and functional disability, which are therapeutic effects.
No
The device described is a knee prosthesis, intended for use as a replacement in knee arthroplasty, which is a therapeutic treatment. It does not perform any diagnostic function.
No
The device description clearly states it is a "tricompartmental total knee prosthesis comprised of femoral, patellar, and tibial components with an ultra-high molecular weight polyethylene articular insert," which are physical hardware components.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for replacing a knee joint in patients with various conditions. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details the components of a knee prosthesis (femoral, patellar, and tibial components, articular insert). These are physical implants used in surgery.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing samples from the human body (blood, urine, tissue, etc.)
- Providing information for diagnosis, monitoring, or screening
- Reagents, calibrators, or control materials
The device is a surgical implant intended to replace a damaged knee joint, which falls under the category of a medical device, but not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The TC-PLUS Primary Knee is intended as a cemented surface replacement in treating patients who are candidates for primary total knee arthroplasty or revision knee arthroplasy. It is indicated for degenerative, post traumatic or rheumatoid arthritis, avascular necrosis of the femoral condyle, post-traumatic loss of joint configuration, in particular in the event of patello-femoral erosion, functional disability or an earlier patellectomy; moderate varus, valgus or flexure deformity and to correct earlier unsuccessful attempts at surgery.

Device Description
Subject of this premarket notification is the TC-PLUS Primary Knee System. The TC-PLUS Primary Knee System is a tricompartmental total knee prosthesis comprised of femoral, patellar, and tibial components with an ultra-high molecular weight polyethylene articular insert. The femoral and tibial baseplate components are offered with or without a plasma-sprayed titanium coating.
The TC-PLUS Primary Knee System is comprised of existing implant components of the previously-cleared VKS Knee System and the TC-PLUS Solution Knee System. The femoral components are the previouslycleared TC-PLUS Solution femoral components available with (K011258) or without (K000666) a titanium plasma-spray coating. The articular insert and tibial baseplate components in the TC-PLUS Primary Knee System are identical to those of the VKS Knee System (K022204). The titanium plasma-sprayed tibial baseplates in the system feature holes to accept cancellous bone screws' for supplemental fixation. The patellar components of the subject knee system are the existing patellar implants cleared as part of K000666.
There are no new implant designs included in this premarket notification other than the addition of a size 12 tibial baseplate and size 20mm thick articular inserts. This 510(k) seeks to combine two existing knee systems into one and to also harmonize the sizing for both systems.

§ 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 Mr. Sinha:
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 (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometric's (OSB's) Division of Postmarket Surveillance at 240-276-3474. For questions regarding the reporting of device adverse events (Medical Device Reporting (MDR)), please contact the Division of Surveillance Systems at 240-276-3464. 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.
