I have had patallar pain for a VERY long time and the patella was also laterally tilted.
I did all the basic things to try and fix it (ice, stretching etc…) my glutes fire just fine as i have been doing glute activation for a long time, i would use a travel roller almost everyday and still not much improvement.
over the last several week i have used the Voodoo bands nearly everyday, and done poliquin step-ups 3-4 times/week and its amazing the difference.
Not only is the pain almost totally gone, but my patella is actually visibly less tilted! I can actually feel the lateral boarder of the patella.
for anyone who had tried everything for knee issues, i STRONGLY recommend Voodoo bands.
