Intended Use

The MOTO™ 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 post-traumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty.

Device Story

MOTO Partial Knee System; cemented unicompartmental knee prosthesis. Components: Co-Cr-Mo femoral component (ISO 5832-4), UHMWPE tibial insert (ISO 5834-2), Ti-6Al-4V tibial baseplate (ISO 5832-3). Used in partial knee arthroplasty to replace articulating surfaces in one compartment. Implanted by orthopedic surgeons in clinical settings. Provides mechanical stability via fixation pegs (femoral) and keel/peg (tibial). Benefits: restores joint function in patients with localized degenerative disease or trauma. Single-use, sterile.

Clinical Evidence

Bench testing only. Studies included fatigue testing under dynamic physiological loads (ASTM F1800), wear testing (ASTM F2083), sterilization validation (ANSI/AAMI/ISO 11137-1/2, ISO 11135-1), accelerated/real-time aging, packaging validation, and pyrogen limit testing (LAL).

Technological Characteristics

Materials: Co-Cr-Mo (ISO 5832-4), UHMWPE (ISO 5834-2 Type 1), Ti-6Al-4V (ISO 5832-3). Fixed bearing design. Cemented fixation. Sterilization: Gamma irradiation or ethylene oxide. Sizes: 10 femoral, 8 tibial insert/tray. Mechanical stabilization via pegs and keel.

Indications for Use

Indicated for patients requiring partial knee arthroplasty due to compartmental primary degenerative or post-traumatic degenerative disease, previous tibial condyle or plateau fractures, deformity, or revision of previous arthroplasty, provided there is sufficient sound bone to seat and support components.

Regulatory Classification

Identification

A knee joint femorotibial metal/polymer non-constrained cemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral condylar resurfacing component or components made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components made of ultra-high molecular weight polyethylene and are intended for use with bone cement (§ 888.3027).

## DEVICE DESCRIPTION

The MOTO™ Partial Knee System is a knee prosthesis designed for cemented use in medial compartment 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 post-traumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty. The femoral component is made of cobalt-chromiummolybdenum (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™ Partial Knee System implants are offered sterile (via gamma irradiation or ethylene oxide), are intended for single use only, and may not be re-sterilized.

The Anatomic Femoral Component (cemented) is anatomically shaped and designed with two (2) fixation pegs for sizes 1 to 7 and three (3) fixation pegs for sizes 8 to 10. Available in ten (10) sizes (1 - 10), the femoral component is offered in both Right Medial (RM) and Left Medial (LM) options for each size.

The Medial Fixed Tibial Insert has a fixed design and is available in five (8) sizes (1 – 8). Each size is offered in six (6) levels of thickness (8, 9, 10, 11, 12, 14 mm).

The Medial Fixed Tibial Tray (cemented) has a fixed bearing design with one fixation keel and peg to ensure primary stability. Available in five (8) sizes (1 - 8), the Medial Fixed Tibial Tray are offered in both Right Medial (RM) and Left Medial (LM) options for each size.

#### INDICATIONS FOR USE

The MOTO™ 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 post-traumatic degenerative disease. previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty.

#### Discussion:

The Indications for Use Statement is similar to the predicate device. 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.

#### PERFORMANCE TESTING

The following studies were performed to support substantial equivalence:

- Fatigue under dynamic physiological loads according to ASTM F1800
- Excessive wear according to ASTM F2083 .
- Sterilization validation in accordance with ANSI/AAMI/ISO 11137-1:2006. ● ANSI/AAMI/ISO 11137-2:2006 and ISO 11135-1:2007
- Accelerated and real time aging
- . Packaging validation
- Limulus Amebocyte Lysate (LAL) testing was evaluated to establish the device meets . pyrogen limit specifications.

#### Conclusion:

Based on the above information, the MOTO™ Partial Knee System can be considered substantially equivalent to the identified predicate devices.
