Device Story

Klassic Knee System is a cemented, semi-constrained total knee joint replacement prosthesis. System components include a symmetric Cobalt Chromium (CoCr) femoral component, a Titanium alloy tibial baseplate, UHMWPE tibial inserts (cruciate retaining or sacrificing), a UHMWPE patellar component, and a UHMWPE dome extension. Designed for primary knee surgery; requires intact medial and lateral collateral ligaments. Components are modular, symmetric, and available in multiple sizes to accommodate patient anatomy. Implanted by orthopedic surgeons in a clinical/hospital setting using provided surgical instrumentation. Device replaces damaged joint surfaces to restore function, reduce pain, and correct deformity. Clinical benefit derived from mechanical restoration of knee joint articulation.

Clinical Evidence

Bench testing only. No clinical data provided. Non-clinical testing included fatigue, disassembly, stability, contact area/stress distribution, range of motion, biocompatibility, sterilization/cleaning validation, and packaging/shelf-life testing. All testing performed in accordance with recognized standards.

Technological Characteristics

Cemented, semi-constrained total knee prosthesis. Materials: Cobalt Chromium (CoCr) alloy femur, Titanium alloy tibial baseplate, Ultrahigh molecular weight polyethylene (UHMWPE) tibial inserts and patella. Modular design with snap-in locking mechanism and set screw. Symmetric design (no left/right orientation). Sterile, single-use. No electronic components or software.

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. Suitable for patients with correctable varus-valgus deformity and moderate flexion contracture. Requires intact medial and lateral collateral ligaments.

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).

## PRODUCT DESCRIPTION

The Klassic™ Knee System consists of two categories of devices: an implantable knee prosthesis and the various instruments needed to perform the surgery and implant the femoral, tibial and patellar components. The Klassic "Knee System allows for simple surgical use and addresses the needs of a wide patient population. The System also has streamlined instrumentation.

The Klassic™ Knee System is a cemented total knee joint replacement system intended for use in primary knee surgery. The System is a semiconstrained design and both the medial and lateral collateral ligaments must be intact. The Klassic" Knee System utilizes a symmetrical design, eliminating the need for left/right orientations. The patellofemorotibial prosthesis includes a metal femoral component, a tibial component consisting of a polyethylene tibial bearing fixed to a metal tibial baseplate, a polyethylene patellar component, a polyethylene dome extension, and a metal tibial insert set screw. The implantable components are provided sterile and are intended for single-use only in a single patient.

The Cobalt Chromium alloy (CoCr) femur has a symmetric design and is available in six sizes for cemented application to accommodate replacement of either left or right knees.

## SECTION 5 510(k) SUMMARY

The Titanium alloy tibial baseplate has a symmetric design and is available in six sizes for cemented application. The tibial baseplate has a modular design to assemble with the tibial insert with a snap-in locking mechanism that is secured with the Titanium allov tibial insert set screw. The System includes two types of tibial inserts which can be used in cruciate retaining and cruciate sacrificing procedures. Both types of tibial inserts have a symmetric design, are composed of ultrahigh molecular weight polyethylene (UHMWPE) and are available in six sizes and four thicknesses (10-16mm). The System also includes a patella composed of UHMWPE which is available in four sizes. Additionally, the System includes a dome extension composed of UHMWPE that connects to the bottom of the tibial baseplate and is available in one size. The UHMWPE material has been utilized in previously cleared devices.

#### TECHNOLOGICAL CHARACTERISTICS

The technological characteristics of the Klassic" Knee System are similar to the predicate devices. Performance data were provided to support the determination of substantial equivalence.

#### SUBSTANTIAL EQUIVALENCE

The proposed indications for use for the Klassic™ Knee System are substantially equivalent to the indications for use for the predicate devices. Any differences in the technological characteristics between the devices do not raise any new issues of safety or effectiveness. Thus, the Klassic" Knee System is substantially equivalent to the predicate devices.

#### TESTING IN SUPPORT OF SUBSTANTIAL EQUIVALENCE DETERMINATION

Extensive bench testing was conducted on the Klassic™ Knee System to evaluate the performance of the device and to support a determination of substantial equivalence to the predicate devices. Non-clinical testing assessed the following aspects of the device:

- Fatigue
- Disassembly
- Stability .
- Contact area and stress distributions .
- Range of motion .
- Biocompatibility .
- Sterilization and cleaning validations .
- Packaging and shelf life .

All testing was performed in accordance with recognized standards. Results confirm that all components of the Klassic" Knee System exhibit the appropriate characteristics for total knee joint replacement, and are substantially equivalent to the predicate devices.
