Yeah, that's a bad one. One strong possibility is that it's misdiagnosed chondromalacia, which would be the reason it's not getting better. Straight legged high kicks seem to be the best fix for that. Another possibility is that it's a foot misalignment problem, in which case you need a very good bike fit therapist guy to look into wedges. In any case, my guess is that the docs are wrong, and that's why it's not getting better. Football docs are not cycling docs.
