New CT scan could spot loose knee implants sooner

This study tests a new way to take CT scans of the knee while it is bearing weight, like standing. The goal is to see if this method can detect small movements of a knee replacement implant earlier than standard X-rays. The study will include 15 people, some with healthy knees and some with knee replacements. If successful, this approach could help doctors identify implant loosening sooner and improve long-term outcomes after knee replacement surgery.
