I went a little nuts (to be honest) and was doing 1.5 - 2 hours a day
The outcome if you have surgery is as follows...if your lucky youll regain a decent knee to do some sports. But you wont EVER have the dependable knee you had before.
Since then I have felt soreness, tightness and heat in the front and medial side of my knee. Sometimes just weird tingly feelings and numbness. It is a minor annoyance, but I must say that it makes it harder to focus on things other than my knee. It seems to be gradually getting better, but I wonder whether it is just a little disturbance, just an aggravation of the meniscal tear or the meniscal tear is getting worse and worse.
