Intended Use

The TriTis Tibial Fixation System is intended for use in the fixation of ligament and tendon grafts during anterior cruciate ligament (ACL) reconstruction of the knee.

Device Story

TriTis Absorbable Tibial Reconstruction System provides soft tissue fixation for ACL reconstruction. Three-piece implant includes graft cleat, washer, and fixation screw to secure graft in bone tunnel. System includes instrumentation for bone tunnel preparation and device placement. Used by surgeons in clinical/OR settings. Modifications include addition of 12 mm diameter graft cleat and 12 mm dilator instrument. Device maintains design integrity for soft tissue fixation.

Clinical Evidence

Bench testing only. Performance data included simulated use testing and system strength testing to confirm design integrity.

Technological Characteristics

Absorbable tibial fixation system consisting of a three-piece implant (graft cleat, washer, fixation screw) and associated instrumentation. Materials are identical to the predicate device. Mechanical fixation principle.

Indications for Use

Indicated for fixation of ligament and tendon grafts during anterior cruciate ligament (ACL) reconstruction of the knee.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

#### 2. DEVICE:

Trade Name: Scandius TriTis™ Absorbable Tibial Reconstruction System Classification Name: Fastener, Fixation, Biodegradable, Soft Tissue The Product Code: MAI

# 3. PREDICATE DEVICE:

The predicate device used to determine substantial equivalence for modifications to the Scandius TriTis Absorbable Tibial Reconstruction System was the previously cleared Scandius TriTis Absorbable Tibial Reconstruction System.

#### 4. DEVICE DESCRIPTION:

The TriTis Absorbable Tibial Reconstruction System consists of a three piece implant designed to provide soft tissue fixation for tibial anterior cruciate ligament (ACL) reconstruction. The graft cleat secures the soft tissue graft in the tunnel. The washer and fixation screw secure the ends of the graft and cleat to the bone.

The System includes instrumentation to prepare the bone tunnel and place the device as well as a sterilization tray.

The modifications made to the device that are the subject of this submission are:

Add a new, 12 mm diameter graft cleat implant size, and a new, 12 mm Dilator instrument. All other device features and instruments remain unchanged.

### 5. INTENDED USE:

The TriTis Tibial Fixation System is intended for use in the fixation of ligament and tendon grafts during anterior cruciate ligament (ACL) reconstruction of the knee.
