Intended Use

The NEO Total Knee System components are indicated for use in skeletally mature individuals, with severe knee pain and disability, undergoing surgery for total knee replacement due to: . Osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, moderate deformities and femoral condyle osteonecrosis. . Failed osteotomies, failed partial knee replacement, or failed total knee replacement whose age, weight and activity level are compatible with an adequate long-term result. Post-traumatic loss of joint configuration, particularly when there is . patellofemoral erosion, dysfunction or prior patellectomy. Moderate valgus, varus, or flexion deformities. . The cruciate retaining (CR) femur with CR tibial insert is for use when the posterior cruciate ligament (PCL) is intact. The CR femur with UC tibial inserts is for use when the PCL is sacrificed. The posteriorly stabilized (PS) femur with PS tibial insert is for use when the PCL is sacrificed. The NEO Total Knee System components are indicated for use only with cement and are single use devices.

Device Story

NEO Total Knee System is a cemented, single-use total knee replacement prosthesis. Components include CoCr femoral components (CR and PS designs), titanium alloy tibial trays, and UHMWPE tibial inserts (CR, UC, PS) and patellar components. Device restores joint function in patients with severe knee pain/disability. Surgeons implant the device in an OR setting. System supports up to 150° active clinical flexion. Output is a mechanical joint replacement; clinical decision-making relies on surgeon assessment of patient anatomy and PCL status to select appropriate component configuration (CR, UC, or PS). Benefits include pain relief and improved joint mobility.

Clinical Evidence

Bench testing only. Evaluations included tibial tray fatigue strength, insert locking mechanism strength, tibial post strength, femorotibial and patellofemoral range of motion, constraint, contact areas, and contact stress.

Technological Characteristics

Materials: Cast CoCr (femoral), titanium alloy (tibial tray), UHMWPE (inserts/patellar). Design: CR, UC, and PS configurations. Dimensions: Femoral sizes 1-10; Tibial trays 1-10; Inserts sizes A-E, 6-21mm thickness; Patellar 26-41mm diameter. Sterilization: Traditional methods. Cemented fixation only. Single-use.

Indications for Use

Indicated for skeletally mature individuals with severe knee pain and disability requiring total knee replacement due to osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, moderate deformities, femoral condyle osteonecrosis, or failed prior knee surgeries (osteotomies, partial or total replacements). Suitable for patients with post-traumatic joint loss, patellofemoral erosion/dysfunction, or moderate valgus/varus/flexion deformities. Contraindicated for patients whose age, weight, or activity level are incompatible with long-term results.

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 Mr. Powell:

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.
