Subject components include posterior stabilizing (PS) femur, femoral pegs, and tibial inserts (standard and E-Link poly). Used by orthopedic surgeons in clinical settings for total knee arthroplasty. Components are available in various sizes/thicknesses to match patient anatomy. Device functions as a mechanical replacement for diseased or damaged knee joints. Benefits include pain relief and restoration of joint function. Substantial equivalence established via engineering analysis and mechanical testing. ## Clinical Evidence Bench testing only. Engineering analysis and mechanical testing performed, including modular peg strength, stability, contact stress, range of motion, knee simulator wear, tibial insert post fatigue, modular disassembly, and patella/femoral subluxation/stress. Compliance with LAL testing per AAMI ST-72. ## Technological Characteristics Semi-constrained knee prosthesis; metal/polymer construction. Includes PS-Post femur, femoral pegs, and tibial inserts (standard and E-Link poly). Cemented and cementless options available. Compliant with AAMI ST-72 for LAL testing. ## 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 - Klassic® Knee System ([K112906](/device/K112906.md)) - Klassic® Knee System-Tibial Stem Extensions ([K140942](/device/K140942.md)) - Klassic® Knee Sombrero Patella ([K150105](/device/K150105.md)) - Klassic® Knee System - Tibial Inserts, 18mm ([K153075](/device/K153075.md)) - Klassic® Knee System - Femur, Nonporous size 7 ([K153310](/device/K153310.md)) - Klassic® Knee System All Poly Tibia ([K162422](/device/K162422.md)) - Klassic® Knee System Tibial Inserts with E-Link® Poly ([K180159](/device/K180159.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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 {1}------------------------------------------------ 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); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
