The summary describes a conventional knee prosthesis and does not mention any AI or ML components or functionalities.
Yes
The "Intended Use / Indications for Use" section states that the device is for the "relief of pain and restoration of motion," which are therapeutic benefits.
No
The provided text describes the Ascent Knee, which is a knee prosthesis designed to replace damaged or diseased knee bone. Its purpose is to relieve pain and restore motion, classifying it as a treatment device, not a diagnostic one.
No
The device description explicitly states it includes "independent Ti-6A1-4V femoral augments," which are hardware components.
No, 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 provided text describes a knee prosthesis (an artificial joint) designed to be implanted in the body to replace damaged knee bone.
- Intended Use: The intended use is to relieve pain and restore motion in the knee due to various conditions. This is a therapeutic use, not a diagnostic one.
The Ascent Knee is a medical device, specifically an implantable orthopedic device, not an IVD.
N/A
Intended Use / Indications for Use
The indications for use of the Ascent Knee are the same as for other conventional knee prostheses. These include the relief of pain and restoration of motion due to noninflammatory degenerative joint diseases, rheumatoid arthritis, deformities of the knee and revisions of previously failed knee replacements. Standard surgical and rehabilitative procedures are indicted with this device. This device is for use with bone cement.

§ 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.

SUMMARY OF SAFETY AND EFFECTIVENESS
Biomet, Inc. Sponsor: Airport Industrial Park P.O. Box 587 Warsaw, IN 4681-0587
Ascent Knee System Device:
Classification: Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis (CFR 888.3560)
Device Description: The Ascent Knee System has independent Ti-6A1-4V femoral augments which are designed to replace damaged or diseased knee bone. Indications include the relief of pain and restoration of motion due to non-inflammatory degenerative ioint disease, rheumatoid arthritis, deformities of the knee and revisions of previously failed knee replacements. The device is intended for use with bone cement.
Potential Risks: The potential risks associated with this device are the same as with any joint replacement device. These include, but not limited to:
- Reaction to bone cement Deformity of the joint Cardiovascular disorders Fracture of the cement Implant loosening/Migration Tissue growth failure
- Blood vessel damage Soft tissue imbalance Delayed would healing Metal sensitivity Fracture of the components Nerve damage
- Bone fracture Infection Hematoma Dislocation Excessive wear
Modifications made were to the Performance Knee femoral augment to produce the Ascent Knee femoral augments.
