Summary

This trial compares two types of knee replacement surgery using a robotic system. Results will be tracked up to 5 years.

Who is the study for?
This trial is for adults over 18 who need a knee replacement due to osteoarthritis or inflammatory arthritis and are willing to follow the study's protocol. They must be scheduled for surgery using the ROSA robotic system and have access to a device that works with an Apple Watch and mymobility App.
What is being tested?
The study compares two types of knee implant devices: Persona Medial Congruent (MC) versus Posterior-Stabilized (PS), both performed with the ROSA robotic system. Participants will be monitored for up to five years after their surgeries.
What are the potential side effects?
While specific side effects aren't listed, typical risks associated with knee replacement may include pain, swelling, infection risk at the surgical site, blood clots, stiffness in the knee joint, and possible wear or malfunction of prosthetic components.
