Indications for Use

Joint replacement is indicated for patients suffering from disability due to: - · degenerative, post-traumatic or rheumatoid arthritis; - · avascular necrosis of the femoral condyle; - · post-traumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy; - · moderate valgus, varus or flexion deformities; This device may also be indicated in the salvage of previously failed surgical attempts.

Device Story

Encore Knee System (including Foundation Lateral Pivot Insert, Foundation Plasma Sprayed Femoral Component, Foundation Ultra Congruent Tibial Insert, and MJS Posterior Stabilized Knee) consists of orthopedic knee joint components. Modification involves updating Instructions for Use (IFU) to standardize documentation and reflect current clinical practice. Devices are intended for surgical implantation by orthopedic surgeons to restore mobility and reduce pain in patients with degenerative joint disease or deformity. No changes to device design, materials, or manufacturing processes were reported; update is administrative/labeling-focused.

Clinical Evidence

No clinical data provided; submission is an administrative update to labeling/IFU.

Technological Characteristics

Knee joint patellofemorotibial/femorotibial polymer/metal/polymer semi-constrained cemented prosthesis. Materials include metal and polymer components. No changes to design or materials reported.

Indications for Use

Indicated for patients with disability due to degenerative, post-traumatic, or rheumatoid arthritis; avascular necrosis of femoral condyle; post-traumatic loss of joint configuration (patellofemoral erosion, dysfunction, or prior patellectomy); or moderate valgus, varus, or flexion deformities. Also indicated for salvage of failed surgical attempts.

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).

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. {5}------------------------------------------------ Page 2 – Ms. Teffany Hutto. 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).
