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).

### D. DEVICE DESCRIPTION

The BC Reflex Uni™ Knee System is a patient-specific prosthesis that consists of femoral and tibial implants for replacement of the medial tibiofemoral compartment of the knee. The patientspecific femoral and tibial components and single-use cutting guides are manufactured from CAD and CAM files generated from Bodycad and off the shelf software, which are based on MRI or CT images of the patient's knee and input from the surgeon. The BC Reflex Uni™ is for cemented use only and is sterilized by gamma radiation.

The subject of this 510(k) is an updated / new design of the femoral component and instruments for implantation, relative to the femoral component described in K163700 and K181302 for the predicate BUKS.

Materials: Wrought Cobalt-28Chromium-6Molybdenum Alloy (CoCrMo; ASTM F1537-11) for the femoral component, wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy (Ti6A4V ELI; ASTM F136-13) for the tibial baseplate and locking pin, Ultra-High-Molecular-Weight Polyethylene (UHMWPE; F648-14) for the tibial insert.

## E. INTENDED USE

The patient-specific BC Reflex Uni™ is indicated for unicompartmental knee arthroplasty (UKA) in patients with advanced knee osteoarthritis (OA) of the medial compartment with evidence of adequate healthy bone to support the implanted components. Candidates for unicompartmental knee replacement include those with:

- · joint impairment due to osteoarthritis or traumatic arthritis of the knee,
- · varus deformity of the knee, and
- as an alternative to tibial osteotomy in patients with unicompartmental OA.

The patient-specific BC Reflex Uni™ components fit within an envelope of dimensions that are specific to each patient. The BC Reflex Uni™ femoral component and tibial baseplate are intended for cemented fixation.

## F. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE

The BC Reflex Uni™ described in this 510(k) notification has the same intended use and general technological features as the predicate devices cleared by FDA in K163700 and K181302 (BUKS). The design modifications to the femoral component include elimination of the screw for ancillary fixation, replacing the resurfacing geometry of the bone-cement surface of the femoral component with a more traditional angular box geometry, and changes to instrumentation associated with the change in design of the femoral component. Comparison of the design features of the BC Reflex Uni™ femoral component with those of the original BUKS femoral component (K163700, K181302) and the ZUK reference device, and results of performance and simulated-surgery verification testing of the subject BC Reflex Uni™ Knee System has established substantial equivalence of the subject, predicate, and reference devices.

{5}------------------------------------------------

#### G. PERFORMANCE DATA

The following performance tests were performed for the BC Reflex Uni™ Knee System:

- Femoral component fatigue strength per ASTM WK51649 Standard Test Method for . Fatigue Testing of Total Knee Femoral Components under Closing Conditions.
- . Surgeon-user verification cadaver surgeries with the BC Reflex Uni™ femoral component and instruments.

The results of performance testing demonstrated substantial equivalence of the subject, predicate, and reference devices.

## H. CONCLUSION

The BC Reflex Uni™ subject components of this 510(k) notification are substantially equivalent and share the same intended use as the predicate BUKS cleared in K163700, K181302, and K191150, and the reference device (ZUK, K033363).
