Intended Use

The b-ONE™ MOBIO™ Total Knee System is intended for total knee arthroplasty due to the following conditions: 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 Posterior Stabilized Plus (PS+) components: Ligamentous instability requiring implant bearing surface geometries with increased constraint. Absent or nonfunctioning posterior cruciate ligament. Severe anteroposterior instability of the knee joint. The b-ONE™ MOBIO™ Total Knee System is intended for implantation with bone cement only. b-ONE™ MOBIO™ Total Knee System components are not intended for use with other knee systems.

Device Story

Modular artificial knee replacement system; replaces diseased knee joint to restore function. Components include symmetric cemented femoral components, tibial baseplate, tibial inserts with locking wires, and patellar resurfacing button. PS and PS+ variants provide increased constraint for ligamentous instability. Implantation requires bone cement; system is closed (no interchangeability with other manufacturers). Intended for use by orthopedic surgeons in clinical settings. Benefits include restoration of joint function and stability for patients with degenerative or traumatic knee conditions. Subject device adds UHMWPE crosslinked with 0.1% tocopherol (Vitamin E) to existing system line.

Clinical Evidence

Bench testing only. Provided characterization of Vitamin E UHMWPE insert material, wear testing, and biocompatibility studies to support substantial equivalence.

Technological Characteristics

Modular knee prosthesis; materials include metal and UHMWPE crosslinked with 0.1% tocopherol. Features symmetric femoral components, tibial baseplate, and patellar button. Posterior stabilized (PS/PS+) design. Cemented fixation only. Supplied sterile, single-use.

Indications for Use

Indicated for patients requiring total knee arthroplasty due to painful, disabling joint disease (osteoarthritis, traumatic arthritis, avascular necrosis, rheumatoid arthritis), post-traumatic loss of joint function, moderate varus/valgus/flexion deformity, revision of failed knee replacement, or distal femur/proximal tibia fractures. PS and PS+ components indicated for ligamentous instability, absent/nonfunctioning posterior cruciate ligament, or severe anteroposterior instability.

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 Allison Gecik:

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. 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

# Device Description/Technological Characteristics:

The b-ONE™ MOBIO™ Total Knee System is a modular artificial knee replacement system comprised of symmetric cemented femoral components with optional femoral distal pegs, symmetric cemented tibial baseplate, symmetric tibial inserts with locking wires, symmetric patellar resurfacing button, and reusable surgical instruments. The therapeutic effect is replacement of the diseased joint with artificial components to restore joint function. The system is a posterior stabilized device two options for posterior stabilization, a PS and a PS+. The PS+ is designed with additional constraint when more stability is required. Compatibility of the system components is only claimed with the b-ONE Total Knee System. There is no allowed interchangeability with systems manufactured by other companies.

The purpose of this submission is to add a line extension to the existing system to offer the Tibial Inserts and Patella components in UHMWPE Crosslinked with 0.1% tocopherol.

All system components are supplied sterile and are single use devices.
