I Had A Partial Subluxion Of My Patella Or I

I had a partial subluxion of my patella or i partially dislocated my pattale about 7 months ago I went to a doctor got crutches for 2 weeks then went back and got assigned some exercises and then wore a knee brace. Went back again after a couple of months because I still was having problems had Physical Thereapy one day kept doing those exercises and started taking anti inflammatory pills but now it still hurts I can't keep it bent for long or it aches. After the injury my knee locks more and pops more but dosent hurt when it pops.
