Outcome Measures

Primary Outcomes (1)

  • Radiograph Assessment of Progressive Tibial Radiolucencies

    Progressive tibial radiolucency will be derived in accordance with the following definitions: Absent: No evidence of an increase in either radiolucency extent (number of zones involved) or measured width within a zone. Present: Presence of either: An increase in the number of zones with a measured tibial radiolucency, OR an increase in the measured tibial radiolucency width within a zone of \>0.5 mm. Unable to assess: One or more of the component factors necessary to derive progressive tibial radiolucency is unavailable.

Eligibility Criteria

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

You may qualify if:

  • Patient is at least 18 years of age.
  • Patient qualifies for a primary cementless tibia total knee arthroplasty based on physical exam and medical history, including diagnosis of severe knee pain and disability due to at least one of 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.
  • The salvage of previously failed surgical attempts that did not include partial or total knee arthroplasty of the ipsilateral knee.
  • Patient has participated in the study-related Informed Consent process.
  • Patient is willing and able to provide written Informed Consent by signing and dating the IRB approved Informed Consent Form.
  • Patient is willing and able to complete scheduled study procedures and follow-up evaluations as described in the Informed Consent Form.
  • Independent of study participation, patient is a candidate for commercially available cementless Persona TM tibial knee component, implanted in accordance with product labeling.

You may not qualify if:

  • Previous history of infection in the affected joint.
  • Active local or systemic 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 accompanied by an ulcer of the skin or a history of recurrent breakdown of the skin.
  • Patient has previously received partial or total knee arthroplasty for the ipsilateral knee.
  • Patient is currently participating in any other surgical intervention studies or pain management studies.
  • Patient is known to be pregnant or considered a member of a protected population (e.g., prisoner, mentally incompetent, etc.).
  • Patient has a known or suspected sensitivity or allergy to one or more of the implant materials.
