Intended Use

The Klassic HD® Hip System is intended for prosthetic replacement without bone cement in treatment of the following: Patient conditions of non-inflammatory degenerative joint disease (NIDJD): avascular necrosis, osteoarthritis, ankylosis, protrusio acetabuli and painful hip dysplasia. Patient conditions of inflammatory joint disease (IJD): rheumatoid arthritis. Those patients with failed previous surgery where pain, deformity, or dysfunction persists. Revision of a previously failed hip arthroplasty. Patients who require a total hip replacement.

Device Story

Klassic HD Hip System is a prosthetic hip replacement system; designed to restore hip joint biomechanics by independently addressing femur/acetabulum size, leg length, offset, and version. Device consists of femoral stems (Klassic Blade and Blade Offset variants) mated with previously cleared CoCrMo or ceramic femoral heads and UHMWPE acetabular components. Used by orthopedic surgeons in clinical settings for total hip arthroplasty. System provides mechanical structural support to replace diseased or damaged hip joints; benefits patients by reducing pain and restoring joint function/mobility.

Clinical Evidence

Bench testing only. No clinical data provided. Evidence consists of range of motion testing, worst-case fatigue testing, and engineering analyses of disassembly and porous coating properties.

Technological Characteristics

Prosthetic hip system components including femoral stems, femoral heads (CoCrMo or ceramic), and acetabular components (UHMWPE). Designed for uncemented (porous-coated) application. System allows independent adjustment of leg length, offset, and version.

Indications for Use

Indicated for patients requiring total hip replacement due to non-inflammatory degenerative joint disease (avascular necrosis, osteoarthritis, ankylosis, protrusio acetabuli, hip dysplasia), inflammatory joint disease (rheumatoid arthritis), failed previous surgery, or revision of failed hip arthroplasty.

Regulatory Classification

Identification

A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.

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.

### Device Description:

The Klassic HD® Hip System employs a prosthesis designed to help surgeons restore hip joint biomechanics intraoperatively by independently addressing the size of the femur and acetabulum. leg length. offset and version. The purpose of this 510(k) is to add Klassic® Blade Femoral Stems and Klassic® Blade Offset Femoral Stems to the Klassic HD® Hip System. The modified stems can be mated with the previously cleared metal (CoCrMo) or ceramic femoral heads and UHMWPE acetabular components of the Klassic HD® Hip System.

## Predicate Devices:

The modified Klassic HD® Hip System is substantially equivalent to the predicate Klassic HD® Hip System (K100445), Klassic HD® Offset Femoral Stem (K133832), and Klassic HD® Extended Offset Femoral Head (K131454) with respect to indications, design, and function.

## Substantial Equivalence:

The company performed Range of Motion and worst case fatigue testing of the Klassic Blade Femoral Stems and Klassic® Blade Offset Femoral Stems. Engineering analyses were conducted to evaluate disassembly properties and porous coating properties of the Klassic® Blade Femoral Stems and Klassic® Blade Offset Femoral Stems. The test results and analyses demonstrated that the modified stems are substantially equivalent to the predicate components.
