ClinConnect Summary

This clinical trial is studying two types of knee implants, the Attune and the Triathlon, to see which one leads to better walking and overall outcomes for patients undergoing knee replacement surgery. As more people need knee replacements due to conditions like arthritis and aging, it's important to find the best options available. The Attune knee is newer, while the Triathlon has been used successfully for many years. Researchers will analyze how well each implant works by looking at patients' walking patterns and their own reports about how they feel after surgery.

To participate in this study, you should be between 65 and 74 years old and need a knee replacement due to arthritis that affects the inner part of your knee. You should be able to walk at a good speed and manage daily activities without too much assistance. If you join the study, you will be randomly assigned to receive either the Attune or Triathlon knee implant. Throughout the trial, there will be regular check-ins to assess your walking ability and recovery. It's also important to note that you’ll need a smartphone to complete online questionnaires as part of the study. Overall, this trial aims to help improve knee replacement surgeries and patient experiences.
