Eligibility
Inclusion criteria
Inclusion criteria: A patient must meet the following criteria to be eligible for participation: 1. Age 18 to 80 years old, inclusive. 2. Qualifies for a primary TKA based on physical exam and medical history, including diagnosis of severe knee pain and disability due to at least one of the following: a) Rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis. b) Collagen disorders and/or avascular necrosis of the femoral condyle. c) Post-traumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy. d) Moderate valgus, varus, or flexion deformities. e) The salvage of previously failed surgical attempts that did not include partial or total knee arthroplasty of the ipsilateral knee. 3. Participated in a study-related informed consent process. 4. Willing and able to provide written informed consent by signing and dating the IRB/EC approved informed consent form. 5. Willing and able to complete scheduled study procedures and follow-up evaluations. 6. Independent of study participation, patient is a candidate for commercially available Persona fixed bearing knee system implanted in accordance with product labelling.
Exclusion criteria
Exclusion criteria: A patient must not meet the following criteria to be eligible for participation: 1. Currently participating in any other surgical intervention studies or pain management studies 2. Previous history of infection in the affected joint and/or other local/systemic infection that may affect the prosthetic joint. 3. Insufficient bone stock on femoral or tibial surfaces. 4. Skeletal immaturity. 5. Neuropathic arthropathy. 6. Any loss of musculature or neuromuscular disease that compromises the affected limb. 7.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective of this study is to obtain implant survivorship and clinical outcomes data for the commercially available Persona fixed bearing implants used in primary total knee arthroplasty (TKA).Timepoint: Each patient will return to the clinic for follow-ups ats at 6 weeks, 6 months, 1 year, 2 years, 3 years and 5 years postoperatively | — |
Secondary
| Measure | Time frame |
|---|---|
| The assessments will include: - Implant survivorship based on removal of the study device - Safety based on incidence and frequency of adverse events - Clinical performance measured by overall pain and function, quality of life data, radiographic parameters and implant survivorshipTimepoint: Each patient will return to the clinic for follow-ups ats at 6 weeks, 6 months, 1 year, 2 years, 3 years and 5 years postoperatively | — |
