Intended Use

The Vanguard® Asymmetrical Patellar is intended for replacement of part of the knee joint in conjunction with a femoral and tibial component. 1. Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis traumatic arthritis where one or more compartments are involved; 2. Correction of varus, valgus, or posttraumatic deformity: 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous total joint replacement procedure. Femoral components and tibial tray components with porous coatings are indicated for cemented and un-cemented biological fixation application. Non-coated (Interlok®) devices and all polyethylene patellar components are indicated for cemented application only.

Device Story

Vanguard® Asymmetrical Patellar Component is a knee prosthesis component; machined from UHMWPE (ASTM F-648). Used in total knee arthroplasty; functions as a bearing surface in conjunction with femoral and tibial components. Designed for cemented application. Intended to restore joint function; alleviate pain; correct deformities. Operated by orthopedic surgeons in clinical/surgical settings. Output is a physical prosthetic interface; clinical decision-making based on patient anatomy and joint pathology.

Clinical Evidence

No clinical data provided. Substantial equivalence determined via non-clinical bench testing, including patellofemoral stability, contact area analysis, and peg shear area analysis, comparing the subject device to predicate performance requirements.

Technological Characteristics

Material: UHMWPE conforming to ASTM F-648. Design: Asymmetrical or medialized dome. Dimensions: 25, 28, 31 x 8 mm; 34 x 8.5 mm; 37, 40 x 10 mm. Application: Cemented only. No electronic components or software.

Indications for Use

Indicated for patients with painful/disabled knee joints due to osteoarthritis, rheumatoid arthritis, or traumatic arthritis; correction of varus, valgus, or posttraumatic deformity; or revision of failed osteotomy, arthrodesis, or previous total joint replacement. All polyethylene patellar components are indicated for cemented application only.

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).

Dear Ms. West:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
