The subject tibial baseplate is porous coated and will be available with and without Howmedica Osteonics' Periapatite (PA) coating. The Triathlon® fixed bearing cementless tibial baseplates are compatible with Triathlon® CR, PS, and CS tibial inserts and patellae. The Triathlon® components proposed in this submission are manufactured from cast cobalt chrome and have a cobalt chrome porous coating, available with and without a peri-apatitie coating. The Triathlon® tibial component is fixed bearing and will be provided in sizes 1 through 8. Compatible cobalt chrome bone screws are also included in this submission in 6.5mm diameter with lengths of 16mm, and 20mm to 60mm in 5mm increments. {1}------------------------------------------------ K072575 # 2/8 ## Intended Use: The Triathlon® Screw-fixation tibial baseplates are intended for use in primary and revision total knee arthroplasty to alleviate pain and restore function. All total knee components presented in this submission are provided sterile for single-use. #### Indications General Total Knee Arthroplasty (TKR) Indications: - Painful, disabling joint disease of the knee resulting from: noninflammatory degenerative . joint disease (including osteoarthritis, traumatic arthritis, or avascular necrosis), rheumatoid arthritis or post-traumatic arthritis. - Post-traumatic loss of knee joint configuration and function. . - . Moderate varus, valgus, or flexion deformity in which the ligamentous structures can be returned to adequate function and stability. - . Revision of previous unsuccessful knee replacement or other procedure. - . Fracture of the distal femur and/or proximal tibia that cannot be stabilized by standard fracture management techniques. Additional Indications for Posterior Stabilized (PS) Components: - . Ligamentous instability requiring implant bearing surface geometries with increased constraint. - . Absent or non-functioning posterior cruciate ligament. The Triathlon® Screw-fixation Tibial Baseplates are intended for cementless use only. #### Substantial Equivalence: The determination of the substantial equivalence of the Triathlon® Screw-fixation tibial baseplate is based on its similarities in intended use, design and sterilization to Howmedica Osteonics' Triathlon® Total Knee System (K051380, cleared 30 August 2005) and Duracon® Total Knee System (K032418 cleared, 11 September 2003). {2}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service JAN - 7 2008 ood and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 Stryker Orthopaedics % Mr. Francisco Haro Regulatory Affairs Specialist 325 Corporate Drive Mahwah, NJ 07430 > K072575 Trade/Device Name: Triathlon Screw-Fixation Tibial Baseplate Regulation Number: 21 CFR 888.3565 Regulation Name: Knee joint patellofemorotibial metal/polymer porous-coated uncemented prosthesis Regulatory Class: Class II Product Code: MBH Dated: December 6, 2007 Received: December 7, 2007 Dear Mr. Haro: Re: 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. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. {3}------------------------------------------------ Page 2 - Mr. Francisco Haro This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
