Intended Use
The REMEDY Stemmed Knee Spacer, which consists of Modular Femoral, Tibial, and Stem Extension Components, is indicated for temporary use (maximum 180 days) as an adjunct to total knee replacement (TKR) in skeletally mature patients undergoing a two-stage procedure due to a septic process where gentamicin is the most appropriate antibiotic based on the susceptibility of the infecting micro-organism(s). The REMEDY Stemmed Femoral Component can be used with a PMMA Tibial Component or an All-Poly tibial component. The device is applied on the femoral condyles (Femoral Component) and on the tibial plate (Tibial Component) following removal of the existing implant and radical debridement. The use of the Stem Extension Component is optional to replace the space occupied by the previous femoral and/or tibial stem (dead space management). Stem Extensions may be used with the Femoral and Tibial components. Moreover, if necessary, the Tibial Component could be coupled with the REMEDY Tibial Insert Wedge when a large tibial defect is present. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). The device is intended for use with antibiotic (gentamicin) bone cement. The REMEDY Stemmed Knee Spacer is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g., resection arthroplasty, fusion, etc.). Because of the inherent mechanical limitations of the device materials, the device is only indicated for patients who will consistently use traditional mobility assist devices (e.g., crutches, walkers, canes) throughout the implantation period, allowing basic joint mobility.
Device Description
The OsteoRemedies' REMEDY Stemmed Knee Spacer (K183017, K223650) are legally marketed devices that are used in skeletally mature patients undergoing a two-stage procedure due to a septic process. The 510(k)-cleared REMEDY Stemmed Knee Spacer is a temporary knee spacer device consisting of independent components (femoral component, tibial component and stem extension components) that can be combined with each other and the optional insert wedge depending on the anatomy of the patient. All components are manufactured from PMMA with gentamicin; the stems are structurally reinforced with a stainless steel core. The subject REMEDY All-Poly Tibial Component is intended to be a line extension to the REMEDY Stemmed Knee Spacer ( K183017, and K223650). The REMEDY All-Poly Tibial Component may be used in lieu of the currently cleared PMMA tibial component.
More Information

No
The document describes a physical medical device (a knee spacer) and its components, materials, and intended use. There is no mention of software, algorithms, data processing, or any terms related to AI or ML. The performance studies listed are mechanical and material property tests, not algorithmic performance evaluations.

Yes
The device is described as an "adjunct to total knee replacement" and is "indicated for temporary use ... due to a septic process". Its purpose is to treat a septic condition, which falls under the definition of a therapeutic device.

No

Explanation: The device is a temporary knee spacer used in total knee replacement procedures, not for diagnosing conditions.

No

The device is a physical implantable medical device (knee spacer components made of PMMA and stainless steel) and not a software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
  • Device Function: The REMEDY Stemmed Knee Spacer is a physical implant used within the body during a surgical procedure. It is a temporary knee spacer designed to manage a septic process in the knee joint.
  • Lack of Specimen Analysis: The device description and intended use do not mention the analysis of any biological specimens. Its function is mechanical support and local antibiotic delivery within the joint space.

Therefore, the REMEDY Stemmed Knee Spacer falls under the category of a surgical implant or device, not an In Vitro Diagnostic.
