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.

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.

The provided text is a 510(k) summary for the REMEDY Stemmed Knee Spacer System with All-Poly Tibial Component. It describes the device, its indications for use, and a summary of performance testing to demonstrate substantial equivalence to predicate devices.

However, the document does NOT contain the specific details required to answer your request regarding acceptance criteria and the study that proves the device meets those criteria.

Here's why and what information is missing:

• No Acceptance Criteria Table: The document does not provide a table outlining specific numerical or qualitative acceptance criteria for the device's performance.
• No Reported Device Performance Data: While it lists categories of performance testing (Fatigue, Wear, Elution, Range of Motion, Interconnection), it does not present the actual results or data points from these tests that would demonstrate how the device performed against any criteria.
• No Details on Study Design for Performance Testing: The summary mentions "Performance Testing" but provides no information on the methodology, sample sizes, data provenance, ground truth establishment, expert involvement, or adjudication methods for these tests. It merely states that "The following performance characteristics of the device have been assessed." These are likely in vitro bench tests, not clinical studies with human subjects or AI algorithm testing.
• No Mention of AI/ML or Software: The entire document refers to a physical medical device (knee spacer system) and its components, made of materials like PMMA and stainless steel. There is absolutely no mention of any AI algorithm, machine learning, software performance, human-in-the-loop studies (MRMC), or standalone AI performance.

Therefore, since the provided text relates to a physical orthopedic implant and not an AI/ML-driven device, the questions about acceptance criteria for AI algorithms, sample sizes for AI test sets, expert involvement in ground truth for AI, MRMC studies, or standalone AI performance are not applicable to this document.

In summary, the provided document does not contain the information requested in your prompt as it pertains to a traditional physical medical device, not an AI/ML powered one.
