Intended Use
The 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 the PS and PS+: - Ligamentous instability requiring implant bearing surface geometries with increased constraint - Absent or nonfunctioning posterior cruciate ligament - Severe anteroposterior instability of the knee joint The MOBIO Total Knee System is intended for implantation with bone cement only. MOBIO Total Knee System components are not intended for use with other knee systems.
Device Description
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.
More Information

No
The summary describes a mechanical knee replacement system and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The device is described as "a modular artificial knee replacement system" with a stated "therapeutic effect" of replacing the diseased joint to restore function. This indicates a direct medical intervention to treat a condition.

No

The device is a knee replacement system used for total knee arthroplasty, which is a therapeutic intervention, not a diagnostic one.

No

The device description clearly states it is a modular artificial knee replacement system comprised of physical components like femoral components, tibial tray, tibial inserts, patellar button, and surgical instruments. It is a hardware device intended for surgical implantation.

Based on the provided information, the MOBIO Total Knee System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use clearly describes a surgical implant for replacing a diseased knee joint. This is a therapeutic intervention performed in vivo (within the body).
  • Device Description: The device description details the components of an artificial knee replacement system, including femoral components, tibial trays, inserts, and a patellar button. These are all physical implants.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, tissue, or urine) to provide information for diagnosis, monitoring, or compatibility testing.

IVD devices are used in vitro (outside the body) to analyze biological samples. The MOBIO Total Knee System is a surgical implant used in vivo to restore joint function.

N/A

Intended Use / Indications for Use

The 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

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.

(a)
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).(b)
Classification. Class II.

The MOBIO Total Knee System is intended for implantation with bone cement only. MOBIO Total Knee System components are not intended for use with other knee systems.

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

  • 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.
