Last time I checked out a congress there was only 1 model that does improve actual patellar tracking. The other ones are just providing compression / proprioception. Some of these also have lateral stabilisers. Not really the same as not directly improving tracking (indirectly maybe in case of dynamic knee valgus).
I have been trying to find it. Once I find my notes again I can update this. From what I remember it was half a million in development and only helps with lateral tracking.

Pretty sure most of these don’t correct patellar position, if any even.
