The summary describes a physical knee implant system and its mechanical testing, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes.
The device is a knee joint replacement system, which clearly falls under the definition of a therapeutic device designed to treat degenerative joint disease.
No
This device is a partial knee system designed for surgical implantation to replace parts of the knee joint, not for diagnosing medical conditions.
No
The device description clearly outlines physical components made of metal and plastic materials intended for surgical implantation, indicating it is a hardware medical device, not software-only.
Based on the provided text, the MOTO™ Lateral Partial Knee System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is for partial knee arthroplasty, which is a surgical procedure to replace part of the knee joint. This is an in-vivo application (within the living body).
- Device Description: The device is described as implants (femoral component, tibial component, tibial insert) made of materials like cobalt-chromium-molybdenum, UHMWPE, and Ti-6Al-4V. These are materials used for surgical implants, not for testing biological samples outside the body.
- Function: The device is designed to replace articulating surfaces of the knee, providing mechanical support and function within the body. IVD devices are used to examine specimens derived from the human body to provide information for diagnosis, monitoring, or treatment.
- Lack of IVD characteristics: There is no mention of the device being used to test blood, urine, tissue, or any other biological sample. There is no mention of reagents, assays, or any other components typically associated with IVD devices.
Therefore, the MOTO™ Lateral Partial Knee System is a surgical implant, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The MOTO™ Lateral Partial Knee System is designed for cemented use in partial knee arthroplasty, if there is evidence of sufficient sound bone to seat and support the components. Partial replacement of the articulating surfaces of the knee is indicated when only one side of the joint is affected due to the compartmental primary degenerative or posttraumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty.

Device Description
The MOTO™ Lateral Partial Knee System is designed for cemented use in partial knee arthroplasty, if there is evidence of sufficient sound bone to seat and support the components. Partial replacement of the articulating surfaces of the knee is indicated when only one side of the joint is affected due to the compartmental primary degenerative or posttraumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty.
MOTO™ Lateral Partial Knee System design is characterized by:
- a femoral component designed to anatomically fit the lateral femoral condyle
- a tibia component, designed to anatomically fit the lateral tibial condyle
- a fixed tibia insert, with a flat articulating surface with rounded border
MOTO™ Lateral Partial Knee System has been designed in cemented version only. The femoral component is made of cobalt-chromium-molybdenum (Co-Cr-Mo per ISO 5832-4), and the tibial component consists of an ultra-high molecular weight polyethylene (UHMWPE per ISO 5834-2 Type 1) insert, and a metal baseplate component (Ti-6Al-4V per ISO 5832-3). The MOTO™ Lateral Partial Knee System implants are offered sterile (via gamma irradiation for the femoral and tibial tray components and ethylene oxide for the tibial insert components), are intended for single use only, and may not be re-sterilized
The Lateral Femoral Component (cemented) is symmetrically shaped (suitable for both left and right side) and designed with two (2) fixation pegs for all the sizes. It is available in seven (7) sizes (1 - 7).
The Lateral Fixed Tibial Insert has a fixed design, is symmetrically shaped (suitable for both left and right side) and is available in eight (8) sizes (1 – 8). Each size is offered in six (6) levels of thickness (8, 9, 10, 11, 12, 14 mm). It is fixed through a snapping mechanism with baseplate.
The Lateral Fixed Tibial Tray (cemented) has a fixed bearing design with one (1) triangular keel and two (2) 'mushroom' shaped pegs to ensure primary stability. Available in eight (8) sizes (1 - 8), the Lateral Fixed Tibial Tray is offered in both Right Lateral (RL) and Left Lateral (LL) options for each size.

IV. Device Description
The MOTO™ Lateral Partial Knee System is designed for cemented use in partial knee arthroplasty, if there is evidence of sufficient sound bone to seat and support the components. Partial replacement of the articulating surfaces of the knee is indicated when only one side of the joint is affected due to the compartmental primary degenerative or posttraumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty.

- a femoral component designed to anatomically fit the lateral femoral condyle
- a tibia component, designed to anatomically fit the lateral tibial condyle
- a fixed tibia insert, with a flat articulating surface with rounded border
4
MOTO™ Lateral Partial Knee System has been designed in cemented version only. The femoral component is made of cobalt-chromium-molybdenum (Co-Cr-Mo per ISO 5832-4), and the tibial component consists of an ultra-high molecular weight polyethylene (UHMWPE per ISO 5834-2 Type 1) insert, and a metal baseplate component (Ti-6Al-4V per ISO 5832-3). The MOTO™ Lateral Partial Knee System implants are offered sterile (via gamma irradiation for the femoral and tibial tray components and ethylene oxide for the tibial insert components), are intended for single use only, and may not be re-sterilized
The Lateral Femoral Component (cemented) is symmetrically shaped (suitable for both left and right side) and designed with two (2) fixation pegs for all the sizes. It is available in seven (7) sizes (1 - 7).
The Lateral Fixed Tibial Insert has a fixed design, is symmetrically shaped (suitable for both left and right side) and is available in eight (8) sizes (1 – 8). Each size is offered in six (6) levels of thickness (8, 9, 10, 11, 12, 14 mm). It is fixed through a snapping mechanism with baseplate.
The Lateral Fixed Tibial Tray (cemented) has a fixed bearing design with one (1) triangular keel and two (2) 'mushroom' shaped pegs to ensure primary stability. Available in eight (8) sizes (1 - 8), the Lateral Fixed Tibial Tray is offered in both Right Lateral (RL) and Left Lateral (LL) options for each size.
V. Indications for Use
The MOTO™ Lateral Partial Knee System is designed for cemented use in partial knee arthroplasty, if there is evidence of sufficient sound bone to seat and support the components. Partial replacement of the articulating surfaces of the knee is indicated when only one side of the joint is affected due to the compartmental primary degenerative or posttraumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty.
Discussion:
The Indications for Use Statement is identical to the predicate device MOTO™ Partial Knee System (K162084). It is also similar to the other predicate devices IFU: the only difference is that the subject device calls out the requirements for "evidence of sufficient sound bone to seat and support the components", and the predicate device cites specific example of degenerative joint disease ("osteoarthritis, traumatic arthritis, or avascular necrosis"). These differences do not create new intended uses for the subject device; the subject and predicate devices are all prostheses intended for use in knee arthroplasty.

The fundamental scientific technology of the modified devices has not changed relative to the predicate devices. The safety and effectiveness of the subject devices is adequately supported by the substantial equivalence information, materials information, and analysis data provided within this Premarket Notification.
Due to the extensive history of use in currently marketed medical devices, biocompatibility testing conducted on the predicate device [ MOTO™ Partial Knee System (K162084)] for the same materials supports the biological safety of the MOTO™ Lateral Partial Knee System.
