Strength balancing training for right leg

[loerting]

I have had osgood schlatter on my right knee before, now I have had knee pain inside the right knee, probably because I trained forehand too hard. I took a break for a week, but it is still a little bit there, and my body tries to avoid doing the lunge. Currently I have to play like Noshad Alamiyan and my game has adapted to being backhand oriented. Does my right thigh not have enough strength, or am I doing something wrong technically? Should I do squats to get more strength or do you recommend any other exercises / tricks? I am stretching after every training.
