The summary describes a mechanical knee implant system and its components, with no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes.
This device is a total knee system designed to replace damaged or diseased knee components, thereby restoring knee function and alleviating symptoms of arthritis. These are characteristic functions of a therapeutic medical device.
No
This device is a total knee replacement system, designed to restore knee function and replace damaged or diseased joints. It is an implantable medical device used for treatment, not for diagnosing conditions.
No
The device description clearly outlines physical components made of materials like CoCr and UHMWPE, which are implanted into the body. This is a hardware-based medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for replacing knee joints due to various forms of arthritis or failed previous surgeries. This is a therapeutic intervention performed in vivo (within the body).
- Device Description: The device is a system of physical components (femoral, tibial, and patellar) made of materials like CoCr and UHMWPE, designed to be surgically implanted into the knee joint.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is a surgical implant used in vivo.

Device Description
The MILESTONE Knee System (MKS) is a primary, fixed-bearing, total knee system designed to replicate the natural anatomy of the knee in order to restore knee function. It was developed to preserve and utilize healthy ligamentous structures, and to restore stability to the knee.
The MKS incorporates femoral, tibial, and patellar components and all associated instrumentation needed for implantation. The femoral and tibial components are provided in left and right configurations. The femoral component is made from CoCr and is offered in a posterior stabilizing (PS) configuration. The tibial component comprises an asymmetric tibial baseplate made from CoCr alloy and an asymmetric PS tibial insert made from UHMWPE. The baseplate is designed to maximize metaphyseal bone coverage on the tibia. The baseplate employs a cruciate type keel to enhance implant fixation and torsion resistance. The tibial insert attaches to the baseplate via a mechanical locking mechanism. All MKS metallic components are available in uncoated variants for cemented use. The patellar component is an all-poly round patella made from UHMWPE, also intended for cemented use.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The MILESTONE Knee System (MKS) implant components were evaluated using Failure Modes and Effects Analysis (FMEA) and biomechanical testing of its predicate CKS components. MKS components employ identical geometry and material characteristics as those employed by their respective predicate CKS components. Therefore, non-clinical bench testing and analyses were provided for these predicate components to validate the safety and effectiveness of the MKS. Further testing of MKS components was deemed unnecessary.

§ 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.

Technological Characteristics/Substantial Equivalence:
Consensus Orthopedics, Inc. (COI) licensed the previously cleared Consensus Knee System (CKS) posterior stabilized (PS), standard, uncoated femoral component (K954818), the CKS PS, reduced lateral profile (RLP), uncoated femoral component (K110950), the CKS PS tibial insert (K954818), the CKS uncoated, pegless, CoCr tibial baseplate (K001456), and the CKS round, all-poly patella (K932837) to TGM Medical for use as the MILESTONE Knee System (MKS). These predicate knee system components employ identical materials, design features, and indications as the respective MKS components. Therefore, the femoral, tibial, and patellar components used with the MKS are substantially equivalent to legally marketed predicate devices (Table 2.1).
