Secondary Outcomes (2)

  • Knee Society Score (KSS) Expectations (pre and post op)

    10 years

  • EuroQol Five Dimension Five Level (EQ-5D-5L) Outcomes Measure

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is of legal age and skeletally mature
  • Patient is willing and able to provide written Informed Consent by signing and dating the IRB-approved Informed Consent document
  • Patient is willing and able to complete scheduled follow-up evaluations as defined in the study protocol
  • Patient qualifies for total knee arthroplasty based upon physical exam and medical history, and meets the approved indications for use of the Persona Ti-Nidium Knee System and Vivacit-E polyethylene articulating surface
  • Independent of study participation, patient is a candidate for the commercially available Persona Ti-Nidium Knee and Vivacit-E polyethylene articulating surface, implanted in accordance with product labeling
  • The Persona Ti-Nidium Total Knee is intended for patients with severe pain and disability due to the following:
  • Rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis.
  • Collagen disorders, and/or avascular necrosis of the femoral condyle.
  • Post-traumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy.
  • Moderate valgus, varus, or flexion deformities.

You may not qualify if:

  • Patient is unwilling to sign the Informed Consent
  • Patient is currently participating in any other surgical intervention or pain management study
  • Patient has a mental or neurologic condition who is unwilling or incapable of following postoperative care instructions
  • Patient has a condition which would, in the judgement of the Investigator, place the patient at undue risk or interfere with the conduct of the study
  • Patient is institutionalized or is a known drug abuser, a known alcoholic or cannot understand the requirements of study participation
  • Previous history of infection in the affected joint and/or other local/systematic infection that may affect the prosthetic joint
  • Insufficient bone stock on femoral or tibial surfaces
  • Skeletal immaturity
  • Neuropathic arthropathy
  • Osteoporosis or any loss of musculature or neuromuscular disease that compromises the affected limb
  • A stable, painless arthrodesis in a satisfactory functional position
  • Severe instability secondary to the absence of collateral ligament integrity
  • Rheumatoid arthritis (RA) accompanied by an ulcer of the skin or a history of recurrent breakdown of the skin
  • The kinematic alignment surgical technique is contraindicated for patients with greater than 5° valgus deformity with medial collateral ligament (MCL) insufficiency
