ClinConnect Summary

This clinical trial is looking to find out which surgical technique helps patients recover better after having a robotic-assisted total knee replacement due to osteoarthritis (OA). Specifically, it compares two methods: the restricted inverse kinematic alignment (restricted iKA) and the adjusted mechanical alignment (aMA). The researchers will mainly measure recovery by how far participants can walk in two minutes, but they will also check for pain levels, satisfaction, and how well the knee functions after surgery.

To participate in this trial, individuals need to be between 50 and 80 years old and diagnosed with OA of the knee, which requires surgery. They should also be generally healthy, without serious other health issues. If someone joins the trial, they will be randomly assigned to one of the two surgical methods and will return for follow-up visits to track their recovery progress. This trial aims to help find the best approach for quicker and better recovery after knee surgery.
