Dear Physical therapist, I am writing because I have had knee pain since last year during basketball season. It is a sharp pain on the outside of my knee, right below to the left of my knee. It hurts after excercise (ex. basketball or volleyball practice). I am in volleyball and basketball. It pops every once in a while. Our athletic trainer at my school says it is a cartilage problem and once my pain gets so intense that I can’t stand it anymore then I will see a knee specialist. What do you think I have? Will I have to get surgery? well write me back as soon as possibleThank you for your time.
