The summary describes a physical implant (interpositional spacer) for the knee and contains no mention of software, algorithms, image processing, AI, or ML.
Yes
The device is intended for use in the osteoarthritic knee to replace lost articular cartilage and treat degeneration, which are therapeutic interventions.
No
The device is described as an interpositional spacer for the treatment of osteoarthritis in the knee, indicating it is a therapeutic or prosthetic device, not one used for diagnosis.
No
The device description clearly indicates a physical "Unicondular Interpositional Spacer System," which is a hardware implant for the knee.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes a device implanted into the knee to treat osteoarthritis. This is a surgical intervention, not a diagnostic test performed on samples outside the body.
- Device Description: The description refers to a "Spacer System," which is consistent with an implantable medical device.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), performing tests in a laboratory setting, or providing diagnostic information based on in vitro analysis.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This device clearly falls outside of that definition.
N/A
Intended Use / Indications for Use
The OTI Unicondular Interpositional Spacer is intended for use in the Osteoarthritic knee, where substantial amounts of articular cartlige have been lost as a result of the disease.
The prostheses will be used in indications for uncemented treatment of the Tibia articulating surfaces (Medial and Lateral) of the following:
Moderate degeneration of the Medial and/or Lateral compartment of the knee (grade II-IV chondromalicia ) and minimal degeneration (grade I-II chondromalacia, no loss of joint space) in the patellofemoral components.

§ 888.3590 Knee joint tibial (hemi-knee) metallic resurfacing uncemented prosthesis.
(a)
Identification. A knee joint tibial (hemi-knee) metallic resurfacing uncemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This prosthesis is made of alloys, such as cobalt-chromium-molybdenum, and is intended to resurface one tibial condyle. The generic type of device is limited to those prostheses intended for use without bone cement (§ 888.3027).(b)
Classification. Class II.

Dear Mr. Son:
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.
