Technological Characteristics

Modular knee prosthesis. Materials: UHMWPE GUR 1020-E (crosslinked with 0.1% tocopherol) and conventional UHMWPE GUR 1020. Locking wire: Cobalt Chrome (ASTM F90). Cemented fixation. Sterile, single-use. No software or electronic components.

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 function, moderate deformity (varus, valgus, flexion), revision of failed procedures, or distal femur/proximal tibia fractures. PS/PS+ versions indicated for ligamentous instability, absent 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.

# Device Description/Technological Characteristics:

The MOBIO Total Knee System is a modular artificial knee replacement system comprised of symmetric cemented femoral components, symmetric cemented tibial tray, 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 purpose of this submission is to introduce a line extension to the b-ONE™ MOBIO™ Total Knee System CR/CR PLUS Tibial Insert components and PS/PS PLUS Tibial Insert Components. Compatibility with the b-ONE™ MOBIO™ Total Knee System tibial baseplate and femoral components remains the same. There is no allowed interchangeability with systems manufactured by other companies.

The subject b-ONE™ MOBIO™ Tibial Inserts are made from UHMWPE GUR® 1020-E Crosslinked with .1% tocopherol and conventional UHMWPE GUR® 1020. This material is the same as that used in the reference and predicate devices. The pre-assembled locking wire is the same locking wire used in the existing Tibial Inserts and is manufactured from Cobalt Chrome conforming to ASTM F90.

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

# Comparison of Technological Characteristics

The design features and materials of the subject devices are substantially equivalent to those of the predicate devices. The MOBIO Total Knee System and the predicate devices share the following characteristics:

- Materials of construction

{5}------------------------------------------------

- Manufacturing processes ●
- Sizes offered
- Product design for shape and macrostructures- only differences to the predicate are dimensions ● specific to the condylar stabilizing features of the subject devices.
- o Sterilization methods

### Performance Data

The following performance data were provided in support of the substantial equivalence determination.

Non-Clinical Studies

- Locking Mechanism Strength
- Range of Constraint ●
- Contact Area and Contact Stress ●
- Tibiofemoral Range of Motion
- Characterization of UHMWPE Insert Material ●
- Bacterial Endotoxin Testing
- Shelf Life Studies .
- Biocompatibility ●
- Wear Testing .

### Conclusion

The information provided above supports that the MOBIO Total Knee System is as safe and effective as the predicate devices with the same intended use. The subject and predicate devices only differ in material. However, applicable reference devices have been cited to support the conclusion that these differences do not raise any new questions of safety and effectiveness. The MOBIO Total Knee System is substantially equivalent to the predicate devices.
