Primary Outcome Measures

Name	Time	Method
<p>The main study parameter is the lowest possible dose to have an accurate<br /><br>measurement of knee movement in a dynamic CT scan, to be able to perform<br /><br>studies on healthy subjects.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>The secondary endpoints are the knee movements as mentioned in the main study<br /><br>parameter; relation between the flexion angle of the knee, the TTTG distance,<br /><br>tibial rotation, patellar tilt and mediolateral displacement of the patella.</p><br>
