Intended Use

The Klassic™ Knee System is intended for prosthetic replacement with the use of bone cement in treatment of the following: - Patient conditions of non-inflammatory degenerative joint disease (NIDID): avascular necrosis and osteoarthritis - Patient conditions of inflammatory joint disease (IJD): rheumatoid arthritis - Patients with failed previous surgery where pain, deformity, or dysfunction persists - Correctable varus-valgus deformity and moderate flexion contracture - Revision of a previously failed knee arthroplasty - Patients who require a total knee replacement

Device Story

Klassic™ Knee System is a cemented, modular total knee joint replacement system. This submission adds 18mm Ultra-PS and 18mm CR/Congruent tibial inserts to the existing system. Components are manufactured from ultrahigh molecular weight polyethylene. Device is used by orthopedic surgeons in clinical settings to replace damaged knee joints, addressing pain, deformity, or dysfunction. Output is a physical prosthetic implant. Benefit to patient is restoration of joint function and pain relief.

Clinical Evidence

Bench testing only. Engineering analyses were performed to evaluate resistance to modular disassembly and stability characteristics of the new 18mm tibial inserts compared to previously cleared components.

Technological Characteristics

Cemented, modular total knee joint replacement system. Components: 18mm Ultra-PS and 18mm CR/Congruent tibial inserts. Material: Ultrahigh molecular weight polyethylene. Design: Semi-constrained, patellofemorotibial prosthesis.

Indications for Use

Indicated for patients requiring total knee replacement due to non-inflammatory degenerative joint disease (avascular necrosis, osteoarthritis), inflammatory joint disease (rheumatoid arthritis), failed previous surgery, or revision of failed knee arthroplasty; includes patients with correctable varus-valgus deformity and moderate flexion contracture.

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).

Dear Mr. Weaber:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

## Indications for Use:

The Klassic™ Knee System is intended for prosthetic replacement with the use of bone cement in treatment of the following:

- Patient conditions of non-inflammatory degenerative joint disease (NIDJD): . avascular necrosis and osteoarthritis
- . Patient conditions of inflammatory joint disease (IJD): rheumatoid arthritis

- Correctable varus-valgus deformity and moderate flexion contracture ●
- Revision of a previously failed knee arthroplasty
- Patients who require a total knee replacement ●

## Device Description:

The Klassic™ Knee System is a cemented total knee joint replacement system comprised of modular components with varying sizes available for each component. The purpose of

{4}------------------------------------------------

this Special 510(k) is to add 18mm Ultra-PS and 18mm CR/Congruent tibial inserts to the Klassic™ Knee System. These components are manufactured from ultrahigh molecular weight polyethylene and each is available in 6 sizes.

## Predicate Devices:

The modified Klassic™ Knee System is substantially equivalent to the predicate Klassic™ Knee System (K112906) with respect to indications, design, and function. The information summarized in the Design Control Activities Summary demonstrates that the 18mm Ultra-PS and 18mm CR/Congruent tibial insert met the pre-determined acceptance criteria for the verification activities.

### Substantial Equivalence:

Engineering analyses were performed on the 18mm Ultra-PS and 18mm CR/Congruent tibial inserts and the previously cleared tibial inserts to evaluate their resistance to modular disassembly and stability characteristics. The results of these analyses indicate that the 18mm Ultra-PS and 18mm CR/Congruent tibial inserts are substantially equivalent to the predicate components.
