Study Population

Patients over 18 years old with indication of Total Knee Arhtroplasty

You may qualify if:

  • Male or female
  • Needs a primary TKA and he/she is Persona® knee implant compatible
  • Diagnosed with non-inflammatory degenerative joint disease (e.g., osteoarthritis, post-traumatic arthritis, avascular necrosis, etc.)
  • Over 18 years old
  • Able to:
  • Understand what participation in the study entails and willing to consent (patient or his/her legal guardian) to participate in the study by signing and dating an IRB/EC approved inform consent form. and
  • Follow surgeon/staff instructions, and
  • Return for all follow-up evaluations, and
  • Able and willing to undergo a preoperative radiographs (all cases)
  • Meets an acceptable preoperative medical clearance and is free of or treated for cardiac, pulmonary, hematological or other conditions that would pose excessive operative risk.
  • Has a presence of varus or valgus deformity of 15 degrees or less.

You may not qualify if:

  • Is currently enrolled in an investigational new drug or device study
  • Has an active infection (including septic knee, distant infection, or osteomyelitis)
  • Has neurological disorders (including, but not limited to Parkinson's disease)
  • Has had a prior ipsilateral unicompartmental knee arthroplasty, TKA, knee fusion or patellectomy.
  • Has hip or knee ankylosis.
  • Have indications of intra- and/or extra-articular deformations that would eliminate or tend to eliminate adequate implant support or prevent the use of an appropriately sized implant, such as polio, history of tibial plateau fracture, etc.
  • Has any metal within 150 mm of the joint line for the operative-side knee.
  • Has knee deformities greater than 15 degrees of fixed varus, valgus, or flexion contracture on initial physical examination.
  • Is a female who is pregnant or lactating
  • Is currently involvement in any personal injury litigation, medical-legal or worker's compensation claims
  • Has arterial disease or stents that would exclude the use of a tourniquet.
  • Has insufficient quality or quantity of bone to support the implant due to prior knee surgery (or surgeries), cancer, metabolic bone disease, osteoporosis/osteopnea (diagnosed or treated with medication), active/old/remote infection, etc.
  • Has a mental condition that may interfere with his/her ability to give an informed consent or interfere with his/her ability or willingness to fulfill the requirements of the study.
  • Has a condition that would place excessive demands on the implant (e.g., Charcot's joints, muscle deficiencies, multiple joint disabilities, skeletal immaturity, etc.).
  • Has collateral ligament insufficiency.
