Intended Use

Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis, and/or traumatic arthritis where one or more compartments are involved. 2. Correction of varus, valgus, or posttraumatic deformity. 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous joint replacement procedure.

Device Story

E1® Series A® Patellae are all-polyethylene, 3-peg patellar components for total knee replacement; used in primary or revision applications. Compatible with Biomet cruciate retaining, posterior stabilized, and constrained knee systems. Manufactured from UHMWPE (ASTM F648) treated with 100 kGy gamma irradiation and Vitamin E (α-tocopherol). Device replaces damaged patellar surface to restore joint function; implanted by orthopedic surgeons in clinical/hospital settings. Output is physical restoration of patellofemoral articulation; clinical benefit includes pain relief and improved joint mobility.

Clinical Evidence

Bench testing only. No clinical or animal data required. Performance supported by mechanical tests: contact area stress analysis, mechanical stability analysis, and peg shear testing.

Technological Characteristics

All-polyethylene, 3-peg patellar component. Material: UHMWPE per ASTM F648, cross-linked via 100 kGy gamma irradiation and stabilized with Vitamin E (α-tocopherol). Single-use, sterile. Compatible with Biomet CR, PS, and SSK knee systems.

Indications for Use

Indicated for patients with painful/disabled knee joints due to osteoarthritis, rheumatoid arthritis, or traumatic arthritis; patients requiring correction of varus, valgus, or posttraumatic deformity; and patients requiring revision of failed osteotomy, arthrodesis, or previous joint replacement. All-polyethylene patellar components are 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).

#### Device Description

The E1® Series A® Patellae is an all-polyethylene, 3-peg patella series intended for replacement of part of the knee joint in conjunction with a femoral and tibial component in primary or revision applications. Patella components are available in standard and asymmetric configurations. The proposed devices are manufactured from UHMWPE per ASTM F648 exposed to 100 kGy gamma irradiation and Vitamin E (α-tocopherol).

{1}------------------------------------------------

# BIOME

The E1® Series A® Patellae are compatible with Biomet cruciate retaining (CR), posterior stabilized (PS), and constrained (SSK) knee replacement systems.

#### Intended Use and Indications for Use

- Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis, 1. and/or traumatic arthritis where one or more compartments are involved.
- 2. Correction of varus, valgus, or posttraumatic deformity.
- 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous joint replacement procedure.

Tibial bearings are indicated for use with both cemented and uncemented Biomet tibial trays.

All-polyethylene patellar components are indicated for cemented use only.

#### Summary of Technological Characteristics

The rationale for substantial equivalence is based on consideration of the following characteristics:

- Intended Use: The proposed E1® Series A® Patellae and predicate patella devices have . the same intended use.
- . Indications for Use: The proposed E1® Series A® Patellae and predicate patella devices have the same indications for use.
- . Materials: The proposed E1® Series A® Patellae and predicate patella devices are manufactured from UHMWPE per ASTM F648. The proposed devices utilize the same material and manufacturing process the Biomet E1 Tibial Bearings, K080528.
- . Design Features: The proposed E1® Series A® Patellae incorporate the same design features as the predicate patella devices.
- Sterilization: The proposed E1® Series A® Patellae and predicate devices are provided . sterile via the same sterilization methods for single-use.

#### Summary of Performance Data

Results from mechanical tests and engineering analyses demonstrate the proposed E1® Series A® Patellae are substantially equivalent to the predicate patella devices. No animal or clinical testing was required to support substantial equivalence. A description of the tests and analyses is listed below.

- . Contact area stress analysis and engineering analysis
- . Mechanical stability analysis and engineer analysis
- . Peg shear testing

#### Substantial Equivalence Conclusion

The proposed E1® Series A® Patellae have the same intended use and indications for use as the predicate patella devices. Performance test data and analyses demonstrate the device is as safe and effective and is substantially equivalent to the legally marketed predicate devices.
