Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Difference in rotational stability in degrees as measured by dynamic-CT of intact compared to injured PLC knees. Technical feasibility: - Is the view of the scanner wide enough for a dynamic scan of the knee? During motion the centre of the knee should not move out of the image centre. - Are the images of the knee large enough for the image processors to fit the knee coordinate systems onto the images? - Is this method technical possible and feasible in the normal clinical setting and suited for daily clinical practice? | — |
Secondary
| Measure | Time frame |
|---|---|
| Amount of rotational stability as assessed by dynamic-CT compared to patient functional outcome measures and patient satisfaction measured by questionnaires. Amount of rotational stability as measured by dynamic-CT compared to physical examination (dial test). | — |
