The study tests the safety and benefits of a special knee implant called the Persona Total Knee System. This implant is used in a surgery called total knee arthroplasty (TKA), which means replacing the knee joint. The study lasts for 5 years and needs you to visit the doctor at 3 months, 1 year, 2 years, and 5 years after surgery to check your progress. Doctors will look at how well the implant works and if it helps you feel better. You'll need to give your consent to join and agree to the follow-up visits.

• Study lasts 5 years with follow-up visits at 3 months, 1, 2, and 5 years.
