Additional Information

Official title Persona Outcomes Led Assessment Research in Total Knee Arthroplasty
Description The study design is a prospective, multicenter, study of the commercially available Persona fixed bearing knee implants. The study will require each site to obtain Institutional Review Board (IRB) approval prior to study enrollment. All potential study subjects will be required to participate in the Informed Consent Process. All study subjects will undergo preoperative clinical evaluations prior to their total knee arthroplasty. The post-operative clinical and radiographic evaluations will be conducted at 6 weeks, 6 months, 1 year, 2, 3, 4, and 5 years.
