Intended Use

The NEO™ PS Knee System components are indicated for use in skeletally mature individuals, with severe knee pain and disability, with excised posterior cruciate ligament, undergoing surgery for total knee replacement due to: . Osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, moderate deformities and femoral condyle osteonecrosis. . Failed osteotomies, partial knee replacement, or failed prior total knee replacement whose age, weight and activity level are compatible with an adequate long-term result. . Post-traumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy. . Moderate valgus, varus, or flexion deformities. NEO™ PS Total Knee System components are indicated for use only with cement and are single use devices.

Device Story

Total knee replacement system comprising femoral components, tibial inserts, tibial trays, patellar components, and surgical instrumentation. Designed for high-flexion (up to 150 degrees) in patients with excised posterior cruciate ligament. Used by orthopedic surgeons in clinical/hospital settings. Components implanted via cement fixation to replace damaged joint surfaces, restoring joint configuration and function. Benefits include pain relief and improved range of motion for patients with severe knee pathology.

Clinical Evidence

Bench testing only. Evaluations included tibial tray fatigue strength, insert locking mechanism strength, femorotibial/patellofemoral range of motion, constraint, and contact stress/area analysis. No clinical data provided.

Technological Characteristics

Components manufactured from metals and UHMWPE compliant with implantable materials standards. Semi-constrained cemented prosthesis design. Features include high-flexion geometry. Sterilization method not specified. No software or electronic components.

Indications for Use

Indicated for skeletally mature patients with severe knee pain/disability and excised posterior cruciate ligament requiring total knee replacement due to osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, moderate deformities, femoral condyle osteonecrosis, failed prior surgeries (osteotomies, partial/total knee replacement), or post-traumatic joint loss with patellofemoral dysfunction. Contraindicated for non-cemented use.

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).

Date Summary Prepared: August 6, 2012

#### Device Description:

The NEO PS Knee System includes components designed for total knee replacement. The system includes femoral components, tibial inserts, tibial trays, patellar components and surgical instrumentation:

The Neo PS Knee System femoral component, when used with the Neo PS articular surfaces, is designed to achieve flexion at high angles and provide a clinical ROM up to 150 degrees.

#### Intended Use

The NEO™ PS Knee System components are indicated for use in skeletally mature individuals, with severe knee pain and disability, with excised posterior cruciate ligament, undergoing surgery for total knee replacement due to:

- . Osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, moderate deformities and femoral condyle osteonecrosis.
- . Failed osteotomies, partial knee replacement, or failed prior total knee replacement whose age, weight and activity level are compatible with an adequate long-term result.
- . Post-traumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy.
- . Moderate valgus, varus, or flexion deformities.

NEO™ PS Total Knee System components are indicated for use only with cement and are single use devices.

# NEO PS Knee System 510(k) Summary

#### Predicate Devices:

The NEO CR Knee System is similar to several predicates including the following.

| Trade/Proprietary Name | Manufacturer | 510(K) # | Clearance Date |
|------------------------------|--------------|----------|----------------|
| NEO CR Knee System | Pipeline | K120313 | 4/20/2012 |
| NexGen® LPS-Flex Knee System | Zimmer | K072619 | 11/21/2007 |
| | | K042271 | 10/13/2004 |
| | | K991581 | 07/30/1999 |
| Triathlon PS Knee System | Stryker | K031729 | 9/2/2003 |

#### Technological Characteristics:

The metals and standard UHMWPE material from which the components are manufactured are the same materials used in the predicate knee systems and comply with applicable implantable materials standards. A comparison of design features of the NEO PS Knee System to the predicate knee systems and performance testing confirm that the NEO PS Knee System is capable of withstanding the anticipated physiological conditions associated with the indications for use and is substantially equivalent to the predicate devices.

#### Performance Testing:

The NEO PS Knee System has been evaluated for tibial tray fatigue strength, insert locking mechanism strength, femorotibial range of motion, PS post strength, femorotibial range of constraint, patellofemoral range of constraint, femorotibial contact areas/contact stress, and patellofemoral contact area and contact stress.

#### Substantial Equivalence Information:

The NEO PS Knee System is similar to legally marketed devices listed previously in that they share similar indications for use and incorporate similar technological characteristics. All evaluations determined that the NEO PS Knee System is substantially equivalent to the predicate devices.
