The Pinnacle" Constrained Acetabular Liner is indicated 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.

The Pinnacle Constrained Acetabular Liner is indicated for use with the Pinnacle Acetabular Cup in cementless application.

The subject Pinnacle" Constrained Acetabular Liner is intended to be used with the DePuy Pinnacle" metal acetabular shells and Self-centering™ (bipolar) heads to resurface the acctabular 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 liner is manufactured from ultra high molecular weight polyethylene (UHMWPE), which locks into a porous coated, hemispherical outer shell component manufactured from titanium alloy (Ti-6Al-4V). The liner component articulates with a metal femoral head of an appropriate diameter.

The Pinnacle" Constrained Acetabular Liner mechanically constrains the femoral head within the ID of the liner by providing greater than 180 degrees femoral head capture combined with a titanium constraining ring which fits over the opening diameter of the liner. The UHMWPE liner is held in the metal shell by means of a titanium locking ring.

The subject Pinnacle" Constrained Acetabular Liners are UHMWPE acetabular cup liners that are available in a lateralized neutral or lateralized face-changing orientation. The liners have inner diameters (ID) intended for use with Self-Centering (bipolar) femoral heads within the 40mm-44mm size range. The 62mm-76mm outer diameters (ODs) are geometrically the same as other smaller OD Pinnacle Acetabular Liners cleared in K043058.

I am sorry, but the provided text from K052079 does not contain information about acceptance criteria, device performance metrics, or details of any studies (such as sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, or training set information) that would be used to prove the device meets acceptance criteria.

The document is a 510(k) summary for a medical device (DePuy Pinnacle Constrained Acetabular Liners), which primarily focuses on establishing substantial equivalence to a predicate device based on design, intended use, materials, and manufacturing methods. It states that the "design is identical to the DePuy predicate and does not raise any new issues of safety or effectiveness," which suggests equivalence was established through comparison rather than a detailed performance study with specified acceptance criteria for the new device.

Therefore, I cannot fulfill your request for a table of acceptance criteria and reported device performance or information about a study based on the input provided.

The Pinnacle® Constrained Polyethylene Liner is indicated 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.

The Pinnacle™ Constrained Liner is indicated for use with the Pinnacle® Acetabular Cup in cementless application.

The subject Pinnacle® Constrained Liners are UHMWPE acetabular cup liners that are available in a lateralized neutral or lateralized face-changing orientation. The liners have inner diameters (ID) intended for use with modular femoral heads within the 28mm-36mm size range. The outer mended for assemmer metrically the same as other Pinnacle Acetabular Liners, in a 48mm-60mm size range offering.

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.
