No
The document describes a traditional knee replacement system and does not mention any AI or ML components in its description, intended use, or performance studies.
Yes
The device is described as "a modular artificial knee replacement system" with the therapeutic effect being the "replacement of the diseased joint with artificial components to restore joint function," which directly serves a therapeutic purpose.
No
Explanation: The device is an artificial knee replacement system intended for therapeutic purposes (replacing a diseased joint), not for diagnosing medical conditions.
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 physical hardware components, not software.
Based on the provided text, the MOBIO Total Knee System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- MOBIO Total Knee System Function: The description clearly states that the MOBIO Total Knee System is a "modular artificial knee replacement system" intended for "total knee arthroplasty." Its therapeutic effect is the "replacement of the diseased joint with artificial components to restore joint function."
- No Specimen Analysis: There is no mention of the device analyzing any biological specimens from the patient. It is a physical implant used to replace a damaged joint.
Therefore, the MOBIO Total Knee System falls under the category of a surgical implant or prosthetic device, not an In Vitro Diagnostic device.
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
- 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 cruciate retaining (CR) device type to the system, including the CR femoral component and corresponding CR Tibial inserts. 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 MOBIO Total Knee System includes left and right femoral components for the Cruciate Retaining (CR) system. These components are manufactured from cast cobalt chrome conforming to ASTM F75. The system includes 30 sizes. Sizes 1-10 are provided in right and left versions. Sizes 3-7 are provided in both standard and narrow configurations, with the narrow sizes having a relatively smaller aspect ratio of the medial-lateral to anterior-posterior widths when compared to the standard sizes. Fixed femoral pegs on the femoral components provide additional medio-lateral fixation.
The CR Tibial Inserts are offered in a total of 50 sizes, size A/1-4 through HJ/7-10, with 10 thicknesses ranging from 9 to 25mm (total thickness with Tibial Baseplate is 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.

§ 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.
