The subject Constrained Liner is intended to be used with the DePuy Pinnacle™ metal acetabular shells, and modular femoral heads to resurface the acetabular socket in cementless total hip arthroplasty.
The Pinnacle® Constrained Acetabular Liner is part of a modular system designed to replace the natural articular surface of the hip joint in total hip replacement.

The provided text describes a medical device submission (K043058) for the DePuy Pinnacle® Constrained Acetabular Liners. However, it does not contain information about acceptance criteria, device performance studies, sample sizes, ground truth establishment, or expert involvement for AI/algorithmic performance evaluation.
The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to predicate devices based on similarities in design, intended use, materials, and manufacturing methods. It states: "The design, while not identical to the predicates, does not raise any new issues of safety or effectiveness." This implies that extensive new performance studies (especially in the context of AI/algorithmic output) were likely not required, as the device is built upon established technology and similar to already cleared devices.
Therefore, I cannot fulfill the request to provide a table of acceptance criteria and reported device performance, or details about the study, sample size, ground truth, experts, or adjudication methods because this information is not present in the provided text.
The document states:
- Device Name: DePuy Pinnacle® Constrained Acetabular Liners
- Indications for Use: As a component of a total hip prosthesis in primary or revision patients at high risk of hip dislocation due to a history of prior dislocation, bone loss, joint or soft tissue laxity, neuromuscular disease or intraoperative instability. Also indicated for use with the Pinnacle® Acetabular Cup in cementless application.
- Basis of Substantial Equivalence: Similarities in design, intended use, material, and manufacturing methods to predicate devices (Biomet RingLoc II, Biomet Freedom, DePuy SROM™ Poly-Dial, DePuy Duraloc® Acetabular Cup System Constrained Liners).
Without information on a specific study related to AI/algorithmic performance, I cannot provide the requested details.

§ 888.3310 Hip joint metal/polymer constrained cemented or uncemented prosthesis.
(a)
Identification. A hip joint metal/polymer constrained cemented or uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device prevents dislocation in more than one anatomic plane and has components that are linked together. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular component made of ultra-high-molecular-weight polyethylene with or without a metal shell, made of alloys, such as cobalt-chromium-molybdenum and titanium alloys. This generic type of device is intended for use with or without bone cement (§ 888.3027).(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Hip Joint Metal/Polymer Constrained Cemented or Uncemented Prosthesis.”
