The subject and predicate devices are one in the same and are comprised of several legally marketed Corin Ltd. hip products, which include OMNIIfe Sciences and Apex Surgical hip products. The subject devices include acetabular cups and liners, bone fixation screws, screw hole occluders, cemented and cementless femoral hip stems for primary and revision hip arthroplasty, fixation screws, modular necks, CoCrMo alloy and ceramic femoral heads, dual mobility acetabular systems, and bipolar heads. The purpose of this 510(k) is to notify the FDA of Corin's engineering assessment of the cross-compatibility of the subject devices, identification of conflicts, and updates to the product labeling. The subject hip devices components are manufactured from a variety of materials which include cobalt-chromium-molybdenum alloy, stainless steel alloy, unalloyed titanium, calcium phosphate (Bonit™ coating) Alumina Matrix Composite ceramic (Biolox Delta), and ultrahigh molecular weight polyethylene (UHMWPE), all of which conform to ASTM or ISO standards, or internal standards. The subject femoral hip stems and heads possess the same 12/14 taper design and reference system for determining head and neck offsets.

I am sorry, but the provided text does not contain information about the acceptance criteria and study proving device performance as typically seen in a medical device submission beyond general statements of substantial equivalence. The document is a 510(k) summary for hip replacement components, primarily focusing on cross-compatibility of various existing devices.

The text outlines:

• Device identification and manufacturer information.
• List of numerous predicate devices.
• Detailed descriptions of the indications for use for many hip components (e.g., Corin BiPolar-i, Trinity™ Acetabular System, MetaFix™ Hip, MiniHip™, Trinity™ Dual Mobility, MobiliT™ Cup, OMNI Bipolar Head, OMNI Delta Ceramic Femoral Head, OMNI MOD Hip System, OMNI K1/K2 Hip Systems, Revival™ Modular Hip Stem, TaperFit™, TriFit™ CF/TS Hip). These indications primarily relate to non-inflammatory degenerative joint disease, rheumatoid arthritis, correction of functional deformity, avascular necrosis, fractures, and revision surgeries.
• A "Performance Data" section which describes the types of engineering analyses and bench testing performed to establish cross-compatibility (e.g., ceramic head burst testing, head pull-off, fretting-corrosion, impingement testing, range of motion assessment, comparison of taper geometries, fatigue strength assessment, and contact stress/wear potential).

However, it does not provide:

1. A specific table of acceptance criteria and reported device performance for the types of tests mentioned (e.g., what burst pressure was required vs. achieved). It only lists the types of tests done.
2. Sample sizes used for test sets or data provenance.
3. Number of experts and their qualifications for establishing ground truth (as this pertains to clinical studies, which are not detailed here for performance).
4. Adjudication method.
5. Multi-reader multi-case (MRMC) comparative effectiveness study information.
6. Standalone algorithm performance (as this is not an AI/algorithm-driven device).
7. Type of ground truth used (again, this is not a diagnostic device with "ground truth" in the typical sense).
8. Sample size for training set.
9. How ground truth for the training set was established.

The document's purpose is to demonstrate substantial equivalence of a range of hip components, including their cross-compatibility when used together. The "performance data" refers to the engineering and bench testing conducted to ensure this compatibility rather than clinical performance against specific metrics as one would find for a diagnostic or AI-driven device.

Ask a specific question about this device

The OMNIBotics Knee System is indicated for stereotaxic surgery to aid the surgeon in locating and aligning endoprostheses with these anatomical structures during Total Knee Arthroplasty. The BalanceBot™ is indicated as a tool for adjustment of soft tissue and the femoral implant to reduce instability from flexion gap asymmetry. The OMNIBotics Knee System supports OMNI Apex Knee™ implants and CORIN Unity Knee™ implants.

The OMNIBotics® Knee system is a computer-assisted navigation system with a motorized bone cutting quide that is used by surqeons and operating room (OR) staff to assist in performing stereotaxic total knee arthroplasty (TKA). The OMNIBotics® Knee System consists of the OMNIBotics® Station, ART Knee Application software, the OMNIBot cutting quide for quiding femoral bone resections, the BalanceBot defined as an active (motorized) knee spacer and ligament tensioning device, and the OMNIBotics™ Tracker Kit which is comprised of single-use reflective markers that are fixed onto the associated instruments that provide a frame of reference for tracking by the 3D optical optoelectronic localizer.

The OMNIBotics® Station includes the 3D optoelectronic localizer mounted on an articulated arm, a laptop hosting the ART Knee Software and equipped with a touchscreen, an external LCD monitor and a three-button footswitch as a means for the user to interact with the system. The power supply and communication hardware required for the camera, the laptop, the OMNIBot, and BalanceBot are contained within a single enclosure, the control box, located at the base of the OMNIBotics® Station.

The OMNIBotics® Knee System was originally cleared for use with OMNI Apex Knee™ System implants in K163338. This 510(k) notification demonstrates substantial equivalence of the OMNIBotics® Knee System for use with Corin Unity™ Total Knee System implants.

Acceptance Criteria and Study for OMNIBotics® Knee System

The OMNIBotics® Knee System, when used with Corin Unity knee implants, underwent performance testing and process validations to demonstrate substantial equivalence to its predicate device (OMNIBotics® Knee System, K163338).

1. Acceptance Criteria and Reported Device Performance

2. Sample Size for Test Set and Data Provenance

• Sample Size: Ten (10) cadaver surgeries.
• Data Provenance: Retrospective, using cadaveric subjects. The specific country of origin is not mentioned, but the manufacturer is based in the USA (Corin Ltd., Raynham, MA) and the submitter in Canada (BioVera, Inc., Quebec).

3. Number of Experts Used to Establish Ground Truth and Qualifications

• Number of Experts: Four (4) surgeons.
• Qualifications: The document describes them as "Surgeon-user," implying they are practicing surgeons experienced in Total Knee Arthroplasty. No further specific details (e.g., years of experience, sub-specialty) are provided.

4. Adjudication Method for the Test Set

The document does not explicitly state an adjudication method (e.g., 2+1, 3+1). It reports that the evaluation "demonstrated that the subject device met the established criteria for user requirements, usability, accuracy...". This suggests a consensus or direct assessment against pre-defined criteria by the performing surgeons, rather than a separate adjudication process involving independent reviewers to resolve discrepancies.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No Multi-Reader Multi-Case (MRMC) comparative effectiveness study was mentioned where human readers' performance with and without AI assistance was evaluated. The study focused on validating the device's technical performance and usability, rather than comparing human reader performance.

6. Standalone Performance Study (Algorithm Only)

The study described is not a standalone (algorithm only) performance study. The evaluation involved "surgeon-user verification studies," meaning human surgeons interacted with and utilized the device during the cadaver surgeries. The OMNIBotics® Knee System is a computer-assisted navigation system and cutting guide designed to aid surgeons; therefore, its performance is inherently linked to human interaction.

7. Type of Ground Truth Used

The ground truth was established through direct measurement and assessment by the participating surgeons during the cadaver surgeries. This includes:

• Expert Assessment: Surgeons directly evaluated user requirements, usability, joint stability.
• Measurement-Based Assessment: Accuracy of bone resections, implant position, and magnitudes of gaps would have been determined through intraoperative measurements and post-resection/implantation evaluation, likely against predetermined surgical plans or anatomical landmarks.
• Laboratory Testing: For sterility, endotoxin levels, and biocompatibility of the reflective markers, specific laboratory tests (e.g., gamma radiation validation, ANSI/AAMI ST72. 5.2, ISO 10993-5) were used to establish ground truth.

8. Sample Size for the Training Set

The document does not mention a separate "training set" for the OMNIBotics® Knee System. This device is a navigation and cutting guide system (hardware and software), not an AI model that learns from data in the traditional sense of machine learning. The "ART Knee Application software" is part of the system, but the document does not describe it as having undergone an iterative training process with a dedicated training dataset in the context of this 510(k) submission. The validation primarily focused on the system's performance with the new implant system and revised components.

9. How the Ground Truth for the Training Set Was Established

As no dedicated training set is explicitly mentioned or seems applicable in the context of this device's validation described in the 510(k) summary, this question is not directly addressed by the provided text. The device's underlying algorithms and functionalities would have been developed and verified internally during its engineering and design phases, likely using various forms of testing and pre-clinical data, but these are not delineated as a "training set" in this regulatory submission.
