Identity Imprint CR KRS

The Identity Imprint CR Knee Replacement System is intended for use as a total knee replacement in patients with knee joint pain and disability whose conditions cannot be solely addressed by the use of a prosthetic device that treats only one or two of the three knee compartments, such as unicondylar, patellofemoral or bicompartmental prosthesis.

The Indications for Use include:

· Painful joint disease due to osteoarthritis, traumatoid arthritis or osteonecrosis of the knee.

• · Post traumatic loss of joint function
• · Moderate varus, valgus, or flexion deformity in which the ligamentous structures can be returned to adequate function and stability.

· Failed osteotomies, hemiarthroplasties, and unicondylar, patellofemoral or bicompartmental implants

· Revision procedures provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.

This implant is intended for cemented use only.

Identity Imprint PS KRS

The Identity Imprint PS Knee Replacement System is intended for use as a total knee replacement in patients with knee joint pain and disability whose conditions cannot be solely addressed by the use of a prosthetic device that treats only one or two of the three knee compartments, such as unicondylar, patellofemoral or bicompartmental prosthesis.

The Indications for Use include:

· Painful joint disease due to osteoarthritis, traumatoid arthritis, polyarthritis, polyarthritis or osteonecrosis of the knee.

· Post traumatic loss of joint function

· Moderate varus, valgus or flexion deformity

· Failed osteotomies, hemiarthroplasties, and unicondylar, patellofemoral or bicompartental implants

· Revision procedures provided that the anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.

This implant is intended for cemented use only.

The subject device. Identity Imprint Knee Replacement System, is a knee replacement system including standardized implant sizes combined with standard and patient-specific ancillary surgical instrumentation. As with all Conformis Knee Replacement Systems (KRS), the Identity Imprint Knee Replacement System is semi-constrained knee implants which consist of a femoral, tibial, and/or patellar components. The products are intended for treatment of severe pain and/or disability of the knee damaged by osteoarthritis or trauma.

Using patient imaging (either CT or MR scans), a standard implant is selected that best meets the geometric and anatomic requirements of the specific patient. The femoral components of the subject devices are manufactured from cobalt chromium molybdenum (CoCrMo) alloy. The tibial component includes a metal tray manufactured from titanium alloy and polyethylene inserts. The patellar components are manufactured from UHMWPE.

For user convenience, single-use, standard and patient-specific ancillary orthopedic manual surgical instruments designed for use with the selected Identity Imprint implants are provided to assist in the positioning of the total knee replacement components intraoperatively and in guiding the cutting of bone. In addition, reusable orthopedic manual surgical instruments are provided separately.

The provided text is a 510(k) summary for a medical device (Identity Imprint Knee Replacement System). It does not describe an AI/ML powered device, nor does it contain information about clinical studies with acceptance criteria for device performance, ground truth establishment, or expert evaluations.

Therefore, I cannot extract any of the requested information regarding AI/ML device performance or clinical study details. The document focuses on demonstrating substantial equivalence to a predicate device, primarily through non-clinical performance evaluation of packaging configurations.
