Design outcomes

Primary

Measure	Time frame
The main study parameter is the lowest possible dose to have an accurate measurement of knee movement in a dynamic CT scan, to be able to perform studies on healthy subjects.	—

Secondary

Measure	Time frame
The secondary endpoints are the knee movements as mentioned in the main study parameter; relation between the flexion angle of the knee, the TTTG distance, tibial rotation, patellar tilt and mediolateral displacement of the patella.	—

Countries

The Netherlands
