## Intended Use

The Triathlon Triathlon® All-Polyethylene Condylar Stabilizing (CS) and Posterior Stabilizing (PS) Tibial Implants are for cemented use in primary and revision Total Knee Arthroplasty.

## Device Story

The Triathlon All-Polyethylene Tibial Implants are orthopedic prosthetic components for total knee arthroplasty. These all-polyethylene tibial inserts (CS and PS designs) function as part of a knee replacement system to restore joint function and stability. The device is implanted by an orthopedic surgeon in a clinical/hospital setting. It replaces damaged articular surfaces of the tibia, articulating with femoral components. The device provides mechanical support and stability to the knee joint, addressing pain and deformity. It is designed for cemented fixation to the bone. The device benefits patients by restoring mobility and reducing pain associated with degenerative or traumatic joint disease.

## Clinical Evidence

No clinical data. Substantial equivalence was established through non-clinical bench testing, specifically deflection and micromotion testing, comparing the subject device to the Scorpio All-Poly Tibial Implant and existing Triathlon inserts.

## Technological Characteristics

All-polyethylene tibial components for cemented total knee arthroplasty. Features CS and PS designs. Incorporates a line-to-line boss with a flat posterior section on the keel to ensure even cement mantle distribution. Materials and articular geometry are equivalent to existing Triathlon inserts. Designed for cemented use only.

## Regulatory 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).

Legally Marketed Device to Which Substantial Equivalence is Claimed: Triathlon® Condylar Stabilizing (CS) Lipped Insert: K063423 Triathlon® Posterior Stabilized (PS) Total Knee System: K050539, K042993 and K031729 Scorpio Posterior Cruciate Retaining (CR) Total Knee System All-Poly Tibia: K974556 Scorpio Posteriorly Stabilized (PS) Total Knee System All Poly Tibia: K962152 Triathlon® TS Knee System: K072221

Device Description: The subject devices are a line extension to the Triathlon® Total Knee System (K063423, K050539, K042993 and K031729), providing an all-polyethylene tibial component in CS and PS designs. The All-Poly CS and PS Tibial implants are similar in intended use, design, materials, mechanical testing and operational priniciples as the predicate devices. These components are designed for cemented use only.

There have been no prior submissions for these devices.

These implants are compatible for use with the Triathlon® PS, TS and CR Femoral Components (cemented and uncemented), Triathlon® PS and CR Femoral Components with PA (uncemented), Triathlon® Symmetrical Patellar Component [Conventional or X30 UHMWE] (cemented), Triathlon® Asymmetrical Patellar Component [Conventional or X3® UHMWPE]

{1}------------------------------------------------

(cemented), Triathlon® Metal-Backed Patellar Component with PA (uncemented), Duracon® Symmetric Patellar Component (cemented). Duracon Asymmetric Patellar Component (cemented), and Duracon® Inset Patellar Component (cemented).

Intended Use: The Triathlon Triathlon® All-Polyethylene Condylar Stabilizing (CS) and Posterior Stabilizing (PS) Tibial Implants are for cemented use in primary and revision Total Knee Arthroplasty.

# Indications:

General Total Knee Arthroplasty (TKR) Indications:

- Painful, disabling joint disease of the knee resulting from: non-inflammatory 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 stabilized by standard fracture management techniques.

Additional General Total Knee Arthroplasty (TKR) Indications specific to the PS implant:

- Ligamentous instability requiring implant bearing surface geometries with increased constraint.

- Absent or non-functioning posterior cruciate ligament.
- Severe anteroposterior instability of the knee joint.

The Triathlon All Polyethylene tibial components are indicated for cemented use only.

Summary of Technologies: The Triathlon All-Poly Tibial Implant is designed to be substantially equivalent to the Scorpio All-Poly Tibial Implant and the Triathlon polyethylene inserts. The Triathlon All-Poly Tibial Implant articular surface and periphery is designed equivalently to the existing Triathlon inserts. The bottom side of the All-Poly Tibial Implant is designed with the Scorpio All-Poly Tibial Implant cement features to which was added a line to line boss with flat posterior section that ensures the cement mantle is even around the keel (the Scorpio design allows the keel to be shifted and have varying cement thicknesses).

Non-Clinical Testing: Deflection and Micromotion testing were performed to verify design and establish the basis for substantial equivalence. Micromotion testing was conducted to show the difference in force/motion that the cement and bone interface would see in response to the change of articulation and periphery when utilizing the Scorpio cement features. The deflection test was conducted to make sure that the stiffness (and strength) of the Triathlon All-Poly Tibial Implant component was equivalent or better then the Scorpio All-Poly Tibial Implant with change to the articulation and periphery. Device comparison showed that the proposed device is substantially equivalent in intended use, materials and performance characteristics to the predicate devices.

Clinical Testing: Clinical testing was not required as a basis for substantial equivalence.

{2}------------------------------------------------

Conclusion: The Triathlon® All-Polyethylene Condylar Stabilizing (CS) and Posterior Stabilizing (PS) Tibial Implants are substantially equivalent to the predicate devices identified in this premarket notification.
