Overworked aching 10 months both knees been diagnosed with osgood schlatters, patellar tendonitis, patellofemoral syndrome. Icing, pt, Advil (ibuprofen) don't work?

Clarify diagnosis. You need re-evalaution, muscle strengthening with the pt but also on your own many times a day. Will need x-rays and maybe ultrasound/mri in addiiton to clarify the diagnosis. Need to clarify what you meen and don't work.
Go to next level. You what the problem you have doctor give more stronger anti-inflammatory medication and may be MRI to see how your knee from inside.
