No
The 510(k) summary describes a mechanical knee implant and does not mention any software, algorithms, or AI/ML capabilities. The performance studies are focused on mechanical and material properties.
Yes
This device is a knee replacement system intended for single compartmental knee replacement, which explicitly falls under the definition of a therapeutic device designed to treat a medical condition (osteoarthritis, post-traumatic arthritis, gout, or pseudogout).
No
Explanation: The device described is a knee replacement system (prosthesis) used for treatment, not for diagnosing a condition. Its indications for use describe the conditions it treats, not conditions it helps to identify.
No
The device description clearly states it is a knee prosthesis composed of physical components (femoral and tibial components made of metal and polyethylene), indicating it is a hardware medical device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "single compartmental knee replacement" in individuals with specific knee conditions. This is a surgical procedure involving the implantation of a medical device, not a diagnostic test performed on samples taken from the body.
- Device Description: The device is described as a "single compartmental knee prosthesis," composed of "femoral and tibial components." These are physical implants designed to replace parts of the knee joint.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
The device is clearly a surgical implant used for treatment, not a diagnostic tool.

Intended Use / Indications for Use

Device Description
The DePuy SIGMA® High Performance Partial Knee System is a single compartmental knee prosthesis, composed of individually packaged femoral and tibial components designed to be used in various combinations to replace the natural articular surfaces of the knee joint.
The unicompartmental femoral components are Co-Cr-Mo metal implants, available with or without a porous coating. The metal backed tibial components are Co-Cr-Mo and polyethylene and are available without a porous coating. The all-polyethylene unicompartmental tibial component manufactured from polyethylene.
The unicompartmental femoral components are designed for individuals who require a higher than normal degree of flexion (up to 155°).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The following tests were performed (per FDA's Class II Special Controls Guidance Document: Knee Joint Patellofenerotibial Metal/Polyner Porous-Coated Uncenented Prosheses; Guidance for Industry and FDA) on the SIGMA High Performance (HP) Patial Knee AOX Insert to demonstrate substantial equivalence of safety and efficacy with the predicate device:
- Biocompatibility .
- UHMWPE Material Property Characterization .
- Range of Motion/Constraint ●
- Contact Area/Stress ●
- Wear Testing ●
- Pull-Off .
The proposed devices also meet the requirement of bacterial endotoxin testing as specified in ANSI AAMI ST-72:2011.
Clinical testing was not necessary to demonstrate substantial equivalence.

§ 888.3530 Knee joint femorotibial metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint femorotibial metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace part of 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 consist of a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

Dear Brad Osborne:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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 comply with all the Act's
1
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

PERFORMANCE DATA
SUMMARY OF NON-CLINICAL TESTS CONDUCTED FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE
The following tests were performed (per FDA's Class II Special Controls Guidance Document: Knee Joint Patellofenerotibial Metal/Polyner Porous-Coated Uncenented Prosheses; Guidance for Industry and FDA) on the SIGMA High Performance (HP) Patial Knee AOX Insert to demonstrate substantial equivalence of safety and efficacy with the predicate device:
- Biocompatibility .
- UHMWPE Material Property Characterization .
- Range of Motion/Constraint ●
- Contact Area/Stress ●
- Wear Testing ●
- Pull-Off .
The proposed devices also meet the requirement of bacterial endotoxin testing as specified in ANSI AAMI ST-72:2011.
SUMMARY OF CLINICAL TESTS CONDUCTED FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE AND/OR OF CLINICAL INFORMATION
Clinical testing was not necessary to demonstrate substantial equivalence.
CONCLUSIONS DRAWN FROM NON-CLINICAL AND CLINICAL DATA
The subject DePuy SIGMA High Performance Partial Kneets are substantially equivalent to the predicate SIGMA High Performance Partial Knee System.
