Re: Knee Surgery
You should follow your own doctor and PT recommendations on this.
Personally, I don't do any seated technique anymore, period. My ability to train for the rest of my life is more important to me than my ability to do any particular form or technique.
And I've seen too many folks with decades more yrs in the art than I have repeatedly do the same thing over and over and go back for more and more surgery. Better to learn from others than to do it to ourselves, I think.
