Intended Use

The Genesis II PS Non-modular and CR Non-modular with cement pocket Femoral Components are indicated for: 1. Rheumatoid arthritis. Post-traumatic arthritis, osteoarthritis, or degenerative arthritis. 2. Failed osteotomies, unicompartmental replacement, or total knee replacement. 3. Posterior stabilized knee systems are designed for use in patients in primary and revision surgery, where the anterior and posterior cruciate ligaments are incompetent and the collateral ligaments remain intact. The Genesis II PS Non-modular and CR Non-modular with cement pocket Femoral Components are indicated for use only with cement and are single use devices.

Device Story

Genesis II PS/CR non-modular femoral components are line extensions of the Genesis II Total Knee System. These orthopedic implants replace damaged knee joint surfaces. Components are manufactured from cobalt chromium alloy (ASTM F75-07) and feature optional cement pockets for fixation. Designed for use in primary and revision total knee arthroplasty. Implanted by orthopedic surgeons in clinical/OR settings using standard or ECO instrumentation. Single-use, sterile, gamma-sterilized devices. Output is a restored mechanical joint surface, facilitating improved patient mobility and pain reduction.

Clinical Evidence

Bench testing only. No clinical data was required to support the safety and effectiveness of the subject devices.

Technological Characteristics

Material: Cobalt chromium alloy (ASTM F75-07). Design: Non-modular femoral components (PS and CR versions) with optional cement pockets. Sizes: 1-8, left/right configurations. Energy: Mechanical. Sterilization: Gamma. Connectivity: None. Software: None.

Indications for Use

Indicated for patients requiring primary or revision knee surgery due to rheumatoid, post-traumatic, osteoarthritis, or degenerative arthritis, or failed prior procedures (osteotomies, unicompartmental/total knee replacement). PS components indicated when anterior/posterior cruciate ligaments are incompetent and collateral ligaments are intact. For use only with cement.

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).

## Device Description

Genesis II PS Non-modular and CR Non-modular with cement pocket femoral components are line extension of the Genesis II Total Knee System. It provides a non-modular option of the PS knee which is similar to the nonmodular CR knee in design concept. It is available from size 1-8 and in left and right configuration. The Nonmodular PS/CR femoral components are available with or without the feature of cement pocket. The material is cobalt chromium alloy (ASTM F75-07). The femoral component is a single use device and supplied sterile (Gamma sterilization). The Genesis II PS Non-modular with cement pocket femoral components can be implanted using the standard Genesis II Instrumentation or the Genesis II ECO Instrumentation.

# Intended Use

The Genesis II PS Non-modular with cement pocket Femoral Components are indicated for:

1. Rheumatoid arthritis.

Post-traumatic arthritis, osteoarthritis, or degenerative arthritis. 2.

Failed osteotomies, unicompartmental replacement, or total knee replacement. కి.

Posterior stabilized knee systems are designed for use in patients in primary and revision surgery, where 4. the anterior and posterior cruciate ligaments are incompetent and the collateral ligaments remain intact.

The Genesis II PS Non-modular and CR Non-modular with cement pocket Femoral Components are indicated for use only with cement and are single use devices.

# Performance Data

Design verification has been performed based on requirements outlined in FDA's Draft Guidance for the Preparation of Premarket Notifications (510(k)s) for Cemented, Semi-Constrained Total Knee Prostheses, dated April 1993. Technical report and justifications provided in the submission demonstrated that the Genesis II PS Nonmodular and CR Non-modular with cement pocket Femoral Components met performance requirements and are as safe and effective as the predicate devices.

Clinical data was not needed to support the safety and effectiveness of the subject devices.

## Substantial Equivalence Information

The Smith & Nephew Genesis II PS Non-modular and CR Non-modular with cement pocket Femoral Components are similar to the following commercially available devices regarding indications and.technological characteristics:

- = Smith & Nephew Genesis II Total Knee System (K951987)
#### Conclusion

This Special 510(k) Premarket Notification is being submitted for new Genesis II PS Non-modular and CR Nonmodular with cement pocket Femoral Components that have been designed and developed by Smith & Nephew Inc. Given that the new devices have met all performance requirements and share the same design features, indications, and materials as the predicates, the devices can be considered substantially equivalent to femoral components currently marketed under K951987.
