Intended Use

The Columbus Total Knee System is indicated for use in reconstruction of the diseased knee joint caused by osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, the need to revise failed arthroplasties or osteotomies where pain, deformity or dysfunction persist, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture. The Columbus Knee is designed for use with bone cement.

Device Story

Columbus Total Knee System AS is a semi-constrained cemented knee prosthesis. It consists of femoral and tibial components made of Cobalt Chrome alloy (CoCrMo) with an added Zirconium Nitrate (ZrN) PVD coating. The system is used in orthopedic surgery for knee joint reconstruction. The device is intended for use with bone cement and previously cleared UHMWPE tibial inserts. The addition of the ZrN coating is the only modification to the predicate Columbus Total Knee System. The device is implanted by a surgeon in a clinical/OR setting to restore joint function and alleviate pain in patients with degenerative or post-traumatic knee conditions.

Clinical Evidence

Bench testing only. Testing was conducted in accordance with the "Draft Guidance for the Preparation of Premarket Notifications for Orthopedic Devices-The Basic Elements."

Technological Characteristics

Semi-constrained cemented knee prosthesis. Materials: Cobalt Chrome alloy (CoCrMo) with Zirconium Nitrate (ZrN) PVD coating. Components: Femoral and tibial. Connectivity: None. Software: None. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring knee joint reconstruction due to osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, or revision of failed arthroplasties/osteotomies with persistent pain, deformity, or dysfunction. Includes patients with correctable valgus or varus 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).

## SUBSTANTIAL EQUIVALENCE

Aesculap®, Inc. believes that the Columbus Total Knee System Alternate Surface (AS) is substantially equivalent to Aesculap's Columbus Total Knee System PS (K030367), CR (K022672), Smith & Nephew's Genesis II Zirconium "Oxinium" knee (K962557), and Endotec's (B-P) New Jersey Total knee (K012702).

## DEVICE DESCRIPTION

The Columbus Total Knee System AS includes both CR and PS variants of the femoral and tibial components for cemented use with the previously cleared UHMWPE Columbus tibial inserts. The Zirconium Nitrate ZrN coating is the only change to the previously cleared Columbus Total Knee System. The coated components are still made from Cobalt Chrome alloy (CoCrMo).

## INDICATIONS FOR USE

The Columbus Total Knee System is indicated for use in reconstruction of the diseased knee joint caused by osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, the need to revise failed arthroplasties or osteotomies where pain, deformity or dysfunction persist, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture.

The Columbus Knee is designed for use with bone cement.

## TECHNOLIGICAL CHARACTERISTICS(compared to Predicate(s))

The base material used for the new Aseculap implants is the same as that used to r re base material adsculap devices. The only difference is the addition of a The nium Nitrate (ZrN) coating to the CoCrMo implants. The PVD coating method is Elroomian Nitrate (EPT) council devices as well including the other predicate implants.

## PERFORMANCE DATA

All required testing per "Draft Guidance for the Preparation of Premarket Notifications All roquired (50.mg per or Orthopedic Devices-The Basic Elements" were done where applicable.

Dear Mr. Hull:

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.
