Knee MRI as it bends: a first look at how the knee moves from straight to bent

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Healthy volunteers aged 18–40 will undergo MRI scans of the knee at various degrees of flexion to observe sliding and roll-back motion of the knee joints. The study aims to overcome technical limits of standard MRI coils by using specialized positioning to capture knee movement beyond 30 degrees of flexion. Researchers will analyze how the tibia rotates internally and how the knee surfaces translate relative to the femur during flexion. The findings could improve understanding of knee kinematics and help future imaging approaches. This is an exploratory, interventional imaging study with no therapeutic intervention.
