When it is used correctly the rotational alignment of the trochlear groove is an accurate ...

This video demonstrates this error and shows how it can be avoided by using the Sulcus Line with a simple alignment jig known as the STAG. This has the added advantage of allowing the Sulcus Line to be compared with other rotational landmarks to further improve accuracy. Recent publications and the ongoing clinical trial are summarised.
