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 standard fracture- management techniques Additional Indications for the Posterior Stabilized (PS) and Posterior Stabilized Plus (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 trav, 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. This submission is to add a condylar stabilizing (CR+) Tibial Insert device type to the system. Compatibility of the system components is only claimed with the b-ONE Total Knee System components. There is no allowed interchangeability with systems manufactured by other companies. The CR PLUS Tibial Inserts are offered in a total of 50 sizes, size A/1-3 through HJ/8-10, with 10 thicknesses ranging from 9 to 25mm. The Tibial Inserts are made from Conventional UHMWPE. The Tibial Inserts are pre-assembled with a locking wire which is manufactured from Cobalt Chrome alloy. All system components are supplied sterile and are single use devices.
More Information

No
The document describes a mechanical knee replacement system and its components. There is no mention of software, algorithms, or any technology that would typically incorporate AI/ML. The performance studies listed are mechanical and material tests.

Yes
The device is described as "a modular artificial knee replacement system" and its "therapeutic effect is replacement of the diseased joint with artificial components to restore joint function." This clearly indicates it is a therapeutic device designed to treat a medical condition.

No

This device is a total knee replacement system (prosthetic device) intended to restore joint function, not to identify or diagnose a disease or condition. Its purpose is therapeutic, not diagnostic.

No

The device description clearly states it is a "modular artificial knee replacement system comprised of symmetric cemented femoral components, symmetric cemented tibial trav, symmetric tibial inserts with locking wires, symmetric patellar resurfacing button, and reusable surgical instruments." These are all physical hardware components.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description: The MOBIO Total Knee System is a surgical implant designed to replace a diseased knee joint. It is comprised of physical components (femoral components, tibial tray, tibial inserts, patellar button) that are surgically implanted into the patient's body.
  • Intended Use: The intended use is to treat painful and disabling knee conditions by replacing the joint, not by analyzing samples from the body.

The device is a Class II or Class III medical device (depending on the specific components and regulatory classification) used in a surgical procedure, not an in vitro diagnostic test.

§ 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.
