Researchers want to confirm the implant's safety, durability, and patient satisfaction at 1 and 2 years after surgery. You may be eligible if: - You are 18 or older - You have a clinical indication for a total knee replacement - You are willing to return for follow-up visits at 1 and 2 years - If female, you are not pregnant and not planning pregnancy within 12 months You may NOT be eligible if: - You have a current local or systemic infection - You have significant muscle, ligament, nerve, psychological, or vascular problems - You have poor bone quality or bone destruction that would require a more complex implant - You have an allergy or sensitivity to any implant materials - You have significant knee deformity (HKA angle outside 165°-195°, severe ligament deficiency, or posterior cruciate ligament deficiency) - You have a prior partial or total knee prosthesis requiring revision - You have non-extractable hardware that would conflict with the implant Talk to your doctor to see if this trial is right for you.
