Eligibility
Key inclusion criteria
- Patient is of legal age and skeletally mature

- Patient requires primary total knee arthroplasty due to non- inflammatory degenerative
joint disease (e.g. osteoarthritis, traumatic arthritis, a vascular necrosis,
dysplasia/DDH) or inflammatory joint disease (e.g., Rheumatoid arthritis).

- Patient has met an acceptable preoperative medical clearance and is free from or
treated for cardiac, pulmonary, haematological, etc., conditions that would pose
excessive operative risk

- The patient will be available for follow up throughout the duration of the study.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria

- Cardiac pacemaker

- Surgical clips in head (aneurysm clips)

- Some artificial heart valves

- Electronic inner ear implants

- Metal fragments in eyes

- Electronic stimulators

- Implanted pumps

- Patient has active infection or sepsis (treated or untreated)

- Patient has any vascular insufficiency, muscular atrophy, or neuromuscular disease
severe enough to compromise implant stability or postoperative recovery.

- Patient is female of child-bearing age and not taking contraceptive precautions.

- Patient has inadequate bone stock to support the device (e.g. severe osteopenia,
family history of severe osteoporosis or osteopenia).

- Patient has known moderate to severe renal insufficiency.

- Patient has a known or suspected metal sensitivity.

- Patient is immunosuppressed or receiving high doses of corticosteroids.
