Hi Jay
I had patellar maltracking. In my case caused by outside quads being too strong (or too tight), inside (medial) ones not strong enough (too loose). Also one of the muscles in my butt being too tight.
Phsysio advised exercises, which I admit I
was too lazy to do.
However much later, started yoga and this
has sorted me out. Especially doing the set of movements called Sun Salutations.
Also do Child's pose to stretch the quads.
Both these set of exercises stretch all the muscles in your legs, buttocks and lower back. This does me the power of good.
Having said that, the yoga exercises have turned out to be very similar to the exercises given to my by my physio.
