It seems you havent had many replies so I thought I may as well write something.
Orthopedic consultant said I have shallow throchlear grooves, thin cartilage & chrondomalacia.
But He said that any and all exercise is still good as long as i do not apply rotational stress to my knees.
I have been fervently squatting, and pushed myself hard when switching to SS and fixing my squat form. I had been having problems with knees but continued due to the consensus/belief that a good squat was the best most balanced way to strengthen leg muscles. And strengthening muscles is the advice always given by doctors and therapists to help knee problems like this.
however I must admit, that as I have continued to squat my chronomalacia has gotten worse and worse. My knees also feel less stable & secure.
Squatting heavier weights is supposed to strengthen & tighten ligaments for MORE stable joints. But it feels that my knees are getting looser and less stable.
This is all the opposite of what I had hoped and expected, but I still have faith that this is merely a dip in the through. This may be partially a blind faith, but it is good to keep goals simple. I want to get strong, and getting strong does not happen by not squatting.
Knees having been getting rougher and more painful, but I am indeed hoping they will eventually condition to the new stresses, ROM and alignment caused by extra muscle, forces and motion of squatting. And that huge amounts of muscle will in itself stabilise knees greatly.
