hi,
thank you for the brief history of you. As you mentioned your symptoms you should first take the x-ray of knee in the aeroplane view if it is maltracking of
patella or either an
MRI of knee for any soft tissue damage. also as you mentioned you are having pain in the hip as well, I will be interested to know what is the pain like,
tingling, numbrness, radiating, burning etc what? if it is of anyone of the above you can take an MRI of
lumbar spine to rule out any
soft tissue Injury as well. and treatment will be planned accordingly.
also, before you go for all these why don't you do some exercises and see if your pain can come down. Try performing knee strengthening exercises and core stability recovery
also try performing exercises for gluteus strengthening as well. Pilates will be of good help as well. You can take assistance from a physcial therapsit who can teach you the proper technique to perform.
also I hope that this works out for you and no worries bothers you.
with the grace of God I wish you a good health and excellent recovery
regards
