Intended Use

The EAUM Total Knee System is intended for use in total knee arthroplasty surgery for the following indications: Painful. disabling joint disease of the knee resulting from noninflammatory degenerative ioint disease (including osteoarthritis, traumatic arthritis or avascular necrosis) or rheumatoid arthritis: Post-traumatic loss of knee joint configuration and function; Moderate varus, valgus, or flexion deformity in which the ligamentous structures can be returned to adequate function and stability; Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous arthroplasty procedure. The EAUM Total Knee System is intended for cemented use only.

Device Story

Patellofemorotibial knee prosthesis system for cemented total knee arthroplasty; consists of femoral components (CR and PS designs), tibial baseplate, tibial inserts (CR and PS), and patellar components. Used by orthopedic surgeons in clinical settings to replace damaged knee joints. Components provide structural support and articulation to restore joint function and alleviate pain. Implanted via surgical procedure; requires bone cement for fixation. Benefits include improved joint mobility and pain reduction for patients with degenerative or post-traumatic knee conditions.

Clinical Evidence

Bench testing only. Performance testing conducted according to ISO 7207-2, ASTM F2083, ISO 7207-1, ISO 21536, ISO 14879-1, ASTM F1800, ASTM F1223, ASTM F1814, and ISO 14243-1 to demonstrate mechanical integrity and substantial equivalence.

Technological Characteristics

Materials: Co-Cr-Mo alloy (ASTM F75) for femoral/tibial baseplate; UHMWPE (ASTM F648, Type 1) for tibial inserts/patellar components. Design: Patellofemorotibial prosthesis, CR and PS variants. Dimensions: Range of sizes for femoral, tibial, and patellar components. Sterilization: Gamma irradiation. Connectivity: N/A (mechanical implant).

Indications for Use

Indicated for patients requiring total knee arthroplasty due to painful, disabling joint disease (noninflammatory degenerative, osteoarthritis, traumatic arthritis, avascular necrosis, or rheumatoid arthritis), post-traumatic loss of joint function, or moderate varus/valgus/flexion deformity with stable ligamentous structures. Also indicated for revision of failed osteotomy, arthrodesis, or previous arthroplasty. Intended for cemented use only.

Regulatory Classification

Identification

A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).

Predicate Devices

• Triathlon Total Knee System (K053514)
• Scorpio® NRG™ Knee System Components (K030978)

EAUM Total Knee System

#### INTENDED USE

The EAUM Total Knee System is intended for use in total knee arthroplasty surgery for the following indications:

Painful. disabling joint disease of the knee resulting from noninflammatory degenerative ioint disease (including osteoarthritis, traumatic arthritis or avascular necrosis) or rheumatoid arthritis:

Post-traumatic loss of knee joint configuration and function;

Moderate varus, valgus, or flexion deformity in which the ligamentous structures can be returned to adequate function and stability;

Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous arthroplasty procedure.

The EAUM Total Knee System is intended for cemented use only.

#### DEVICE DESCRIPTION

The EAUM Total Knee System is a patellofemoroltibial knee prosthesis system for cemented total knee arthroplasty. The EAUM Total Knee System consists of the following components: Femoral Components - eight (8) sizes in cruciate-retained (CR) and posterior stabilized (PS) designs, each for left and right sides; Tibial Baseplate (Tray) - nine (9) sizes for use on either the left or right side; Tibial Insert Components - nine (9) sizes for use on either the left or right side, with thicknesses ranging from 6 mm to 24 mm, provided in CR and PS designs; Patellar Components - five (5) sizes in two designs (dome and sombrero); and EAUM Total Knee Instrumentation for use with the system implant components. The components are manufactured from C-Cr-Mo alloy conforming to ASTM F75, Standard Specification for Cobalt-28 Chromium-6 Molybdenum Alloy Castings and Casting Alloy for Surgical Implants (UNS R30075) and UHMWPE conforming to ASTM F648 Standard Specification for Ultra-High-Molecular-Weight Polyethylene Powder and Fabricated Form for Surgical Implants, Type 1 (GUR 1020). The components are sterilized by gamma irradiation.

#### EQUIVALENCE TO MARKETED DEVICES

Corentec Co., Ltd., submits the following information in this Premarket Notification to demonstrate that for the purposes of FDA's regulation of medical devices, the EAUM Total Knee System is substantially equivalent in indications and design principles to the following predicate devices, each of which has been determined by FDA to be substantially equivalent to pre-amendment devices:
