All total knee components presented in this submission are provided sterile for single-use. ## Device Story Triathlon TS Knee System is a semi-constrained, cemented total knee replacement prosthesis; designed for patients with severely deficient bone stock requiring increased stabilization. System includes femoral components, stem extenders, offset adapters, stems, and tibial inserts (standard and TS Plus designs). Implants available in sizes 1-8. Used by orthopedic surgeons in clinical/surgical settings for primary or revision total knee arthroplasty. Device replaces damaged joint surfaces; provides mechanical stability to knee joint; restores function; alleviates pain. Components are implanted via surgical procedure; cemented fixation required. ## Clinical Evidence No clinical data provided. Substantial equivalence is based on design, intended use, and technological similarities to legally marketed predicate devices. ## Technological Characteristics Semi-constrained, cemented patellofemorotibial prosthesis. Materials: metal/polymer. Design: femoral components, stem extenders, offset adapters, stems, and tibial inserts. Sizes: 1-8. Sterilization: provided sterile for single-use. Regulatory class: II. Product code: JWH. ## Regulatory 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). ## Predicate Devices - Howmedica Total Stabilizing Total Knee System ([K973164](/device/K973164.md)) - Triathlon PS Knee System ([K031729](/device/K031729.md)) - Triathlon PS Knee System ([K042993](/device/K042993.md)) - Triathlon Total Knee System ([K053514](/device/K053514.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

E-Mail: Tiffani.Rogers@stryker.com | | Date Summary Prepared: | June 1, 2007 | #### Device Description A total stabilizing version of the Triathlon Total Knee System has been developed and will now include femoral components and tibial inserts compatible with the Triathlon universal tibial components cleared previously. The new Triathlon TS Knee is designed to accommodate patients with severely deficient bone stock who require additional components for increased stabilization. The Triathlon TS System will include femoral components, stem extenders, offset adapters, stems, and tibial inserts in standard and TS Plus design. Implants will be available in sizes 1 through 8. Product descriptions, product codes and engineering drawings are provided for review. {1}------------------------------------------------ ## Intended Use: The Triathlon TS Total Knee System components 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 for Use 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) and Total Stabilizer (TS) Components: - . Ligamentous instability requiring implant bearing surface geometries with increased constraint. - . Absent or non-functioning posterior cruciate ligament. - Severe anteroposterior instability of the knee joint. . #### Additional Indications for Total Stabilizer (TS) Components: - Severe instability of the knee secondary to compromised collateral ligament ● integrity or function. #### Indications for Bone Augments: - . Painful, disabling joint disease of the knee secondary to: degenerative arthritis. rheumatoid arthritis, or post-traumatic arthritis, complicated by the presence of bone loss. - Salvage of previous unsuccessful total knee replacement or other surgical . procedure, accompanied by bone loss. - Salvage of previous unsuccessful total knee replacement or other surgical . procedure, accompanied by bone loss. The Triathlon TS Total Knee System components are intended for cemented use only. #### Substantial Equivalence: The determination of the substantial equivalence of the Triathlon TS total knee system is based on similarities in intended use, design and sterilization to the Howmedica Total Stabilizing Total Knee System (K973164, cleared August 22, 1997), Triathlon PS Knee System (K031729, cleared September 2, 2003 and K042993 cleared January 12, 2005) and the Triathlon® Total Knee System (K053514, cleared January 26, 2006). {2}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.

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 - Ms. Tiffani D. Rogers 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 Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
