Intended Use

The TRULIANT Femoral Components, Tibial Trays are indicated for use in skeletally mature individuals undergoing primary surgery for total knee replacement due to osteoarthritis, osteonecrosis, rheumatoid arthritis and/or post-traumatic degenerative problems. They are also indicated for revision of failed previous reconstructions where sufficient bone stock and soft tissue integrity are present. The TRULIANT Femoral Components, Tibial Inserts, and Tibial Trays are indicated for cemented use only.

Device Story

Truliant femoral components are orthopedic implants used in tricompartmental total knee arthroplasty. Designed for resurfacing femoral bone, these modular components articulate with ultra-high molecular weight polyethylene tibial inserts seated in metal tibial trays. The device features a tapered anterior chamfer and patella flange to minimize implant/bone overhang and a modified cement pocket to improve cement/bone contact. Implantation is performed by orthopedic surgeons in a clinical/OR setting using standard surgical techniques and instrumentation. The device maintains the articulating congruence and patella transition characteristics of the predicate system. By providing a streamlined patella flange, the device aims to improve fit and reduce soft tissue impingement, ultimately restoring knee function for patients with degenerative joint disease.

Clinical Evidence

Bench testing only. Mechanical patellofemoral constraint and contact pressure testing were performed to evaluate the impact of dimensional modifications. Pyrogen testing was conducted per USP <161>, USP <85>, and ANSI/AAMI ST72 to ensure compliance with sterility requirements.

Technological Characteristics

Materials: CoCr alloy. Design: Modular femoral component for cemented total knee arthroplasty. Features: Tapered anterior chamfer, streamlined patella flange, modified cement pocket. Articulation: Ultra-high molecular weight polyethylene tibial insert. Sterilization: Labeled as sterile.

Indications for Use

Indicated for skeletally mature individuals undergoing primary total knee replacement for osteoarthritis, osteonecrosis, rheumatoid arthritis, or post-traumatic degenerative conditions; also indicated for revision of failed reconstructions with sufficient bone stock and soft tissue integrity.

Regulatory Classification

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).

traumatic degenerative problems. They are also indicated for revision of failed previous reconstructions where sufficient bone stock and soft tissue integrity are present.

The TRULIANT Femoral Components, Tibial Inserts, and Tibial Trays are indicated for cemented use only.

# Device Description:

Truliant femoral components are for use in resurfacing femoral bone as part of tricompartmental total knee arthroplasty employing modular components from the Optetrak / Optetrak Logic and Truliant device families.

Truliant femoral components represent modifications to Exactech One Logic femoral components cleared per 510(k) K153776. The proposed Truliant femoral components are identical to predicated One Logic femoral components, with the following key exceptions:

- . Tapered anterior chamfer and patella flange to reduce the appearance of implant / bone overhang
- . Patella flange cement pocket has been modified to increase cement / bone contact area

Additional modifications have been made to facilitate manufacturing.

Like other femoral implants in compatible device families, One Logic femoral components are made from CoCr alloy and are designed to articulate on an ultra-high molecular weight polyethylene tibial insert seated in a metal tibial tray.

Truliant femoral components have the same basic features and articulating surface finish as predicate One Logic femoral components while providing surgeons with an option for a femoral implant with a patella flange that has been comparatively streamlined in the medial-lateral aspects. The articulating congruence featured in all Optetrak and Optetrak Logic femoral-tibial condyle contact is maintained for Truliant femoral components. Cruciate-retaining Truliant femoral components also feature the same patella entry / exit point at the distal trochlear groove featured on predicate One Logic femoral components and intended to enhance patella transition.

The proposed devices operate using same fundamental scientific technology, have the same intended use and design features, employ the same materials of construction, are offered in the same product size scopes, and are implanted using a similar surgical technique and the same or similar instrumentation. The only modifications proposed by this submission are dimensional.

### Exactech® Truliant™ Femoral Components Special 510(k) - 510(k) Summary of Safety and Effectiveness

### Testing Description:

This submission includes results for mechanical patellofemoral constraint and contact pressure testing. Results conclude the proposed Truliant devices do not represent a new worst-case for risks associated with patellofemoral contact.

Pyrogen testing was conducted in accordance with USP <161>, USP <85>, and ANSI/AAMI ST72 to ensure the proposed Truliant components meet recommended limits per FDA's Guidance Document Submission and Review of Sterility Information in Premarket (510(k)) Submission for Devices Labeled as Sterile.

#### Substantial Equivalence Conclusion:

Results of engineering studies referenced in this 510(k) submission demonstrate proposed Truliant devices are substantially equivalent to cited cleared predicate One Logic devices.
