The provided text describes a 510(k) premarket notification for a medical device: "Proven Modular Posterior Stabilized Femoral Component" (part of the "StelKast Proven Cemented, Semi-Constrained Total Knee System"). This document is a letter from the FDA stating that the device is substantially equivalent to legally marketed predicate devices.

The document does not contain information about acceptance criteria, device performance, studies, sample sizes, ground truth establishment, or expert qualifications.

The 510(k) pathway, particularly for devices like this knee component, primarily relies on demonstrating substantial equivalence to a predicate device already on the market. This typically involves performance testing (e.g., mechanical, wear, fatigue) to show that the new device performs as safely and effectively as the predicate, rather than broad clinical studies with human participants that establish de novo performance criteria or compare AI-assisted human performance.

Therefore, I cannot fulfill your request for the specific details about acceptance criteria, study design, and ground truth as these are not present in the provided FDA letter.
