What You Need to Know Before You Apply

What is the purpose of this trial?

This trial studies a knee implant called the Persona Partial Knee System in patients needing partial knee replacement. It aims to see how well the implant works and how long it lasts by tracking patients over time. The Persona® system is a newly launched implant designed for knee replacement with innovations intended for better function and higher flexibility.

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

How is the Persona Partial Knee Replacement treatment different from other treatments for osteoarthritis?

The Persona Partial Knee Replacement is unique because it is a personalized implant designed to fit the patient's anatomy more closely, potentially leading to better movement and comfort compared to standard knee replacements.12345

What data supports the effectiveness of the Persona Partial Knee Replacement treatment for osteoarthritis?

The Persona knee system, used in total knee replacements, has shown promising early outcomes and improved patient-reported outcomes compared to other implants. This suggests that the personalized design of the Persona system may lead to better functional results and patient satisfaction.12346

What Are the Treatments Tested in This Trial?

Interventions

  • Persona Partial Knee system
Trial Overview The study aims to collect data on how well the Persona Partial Knee system works in patients needing knee arthroplasty. It will look at how long the implant lasts (implant survivorship) and measure patient outcomes after surgery using this specific knee replacement device.

Published Research Related to This Trial

In a study of 91 knees from 85 patients who received the Persona® implant for total knee arthroplasty, the implant showed a low revision rate of 2.19% and good clinical outcomes after an average follow-up of 5.9 years.
Patients reported high functional scores, with a mean Oxford Knee Score of 44.21 and a mean range of motion of 120.8º, indicating effective pain relief and improved mobility post-surgery.

The Persona Knee implant system demonstrated high safety and efficacy in total knee arthroplasty, with a 2-year survival rate of 99% and only one revision due to infection among 146 surgeries performed.
Patient-reported outcomes significantly improved post-surgery, with the Oxford Knee Score increasing from an average of 22.1 to 41.8, indicating enhanced pain relief, function, and quality of life for patients.
