Intended Use

The Durcaon® Total Knee System components included in this submission are intended for use in total knee arthroplasty to relieve pain and restore knee functions for indications such as: - Noninflammatory degenerative joint disease including osteoarthritis, traumatic arthritis or avascular necrosis, - Rheumatoid arthritis, - Correction of functional deformity, - Revision procedures where other treatments or devices have failed, - Post-traumatic loss of joint anatomy, particularly when there is patello-femoral erosion, dysfunction or prior patellectomy; and, - Irreparable fracture of the knee These products are intended to achieve fixation with and without the use of bone cement.

Device Story

Duracon® X3™ CS Tibial Insert is a line extension to the Duracon® Total Knee System; functions as a prosthetic component in total knee arthroplasty. Device design is identical to predicate Duracon® tibial inserts; manufactured using X3™ material technology. Intended for implantation by orthopedic surgeons in clinical settings to replace damaged joint surfaces. Provides mechanical articulation and load-bearing support to restore knee function and alleviate pain. Fixation achieved with or without bone cement. Benefits include improved wear characteristics and structural integrity compared to traditional materials.

Clinical Evidence

Bench testing only. Engineering analysis performed to demonstrate equivalent strength to predicate components.

Technological Characteristics

Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented/uncemented prosthesis. Material: X3™ (highly cross-linked polyethylene). Design: Identical to Duracon® Total Knee System tibial inserts. Regulatory Class II; Product Codes JWH, MBH.

Indications for Use

Indicated for patients undergoing total knee arthroplasty requiring pain relief and restoration of knee function due to noninflammatory degenerative joint disease (osteoarthritis, traumatic arthritis, avascular necrosis), rheumatoid arthritis, functional deformity, revision procedures, post-traumatic loss of joint anatomy (patello-femoral erosion/dysfunction/patellectomy), or irreparable knee fracture.

Regulatory Classification

Identification

A knee joint patellofemorotibial metal/polymer porous-coated uncemented 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 is designed to achieve biological fixation to bone without the use of bone cement. This identification includes fixed-bearing knee prostheses where the ultra high molecular weight polyethylene tibial bearing is rigidly secured to the metal tibial base plate.

Special Controls

*Classification.* Class II (special controls). The special control is FDA's guidance: “Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.” See § 888.1 for the availability of this guidance.

# 510(k) Summary of Safety and Effectiveness

### Description:

This submission is a line extension to the Duracon® Total Knee System for a tibial insert. Tibial inserts will be identical in design to the predicate tibial inserts of the Duracon® Total Knee System and manufactured from the same material as the Triathlon® and Scorpio® X3TM Tibial Inserts.

### Indications:

The Durcaon® Total Knee System components included in this submission are intended for use in total knee arthroplasty to relieve pain and restore knee functions for indications such as:

- Noninflammatory degenerative joint disease including osteoarthritis, traumatic . arthritis or avascular necrosis,
- . Rheumatoid arthritis,
- . Correction of functional deformity,
- Revision procedures where other treatments or devices have failed, .

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

- Post-traumatic loss of joint anatomy, particularly when there is patello-femoral . erosion, dysfunction or prior patellectomy; and,
- Irreparable fracture of the knee ●

These products are intended to achieve fixation with and without the use of bone cement.

Substantial Equivalence:

The Duracon® X3™ CS Tibial Inserts are substantially equivalent to the Duracon® Total Knee System, Triathlon® X3™, and Scorpio® X3TM Tibial Inserts in regards to intended use, design, materials, and operational principles as tibia components. The engineering analysis demonstrates that the subject components are substantially equivalent in strength to the predicate components.

Dear Mr. Haro:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
