I have had two ligaments replaced in my knee, as well as two meniscuses repaired and it killed me to get low. NOW if i dont get lower with my knee bend, my knee gives me a fit. I am only about 1 and a half years out of surgery, and the lower i get the better it feels. Might just take you about a week of practice to get your knee used to it, but you should give it a try.

I am the official PRINCIPAL of the NU SKOOL. In my skool, all pupils will throw OLD SKOOL equipment. One may have a new ball or two, but the primary ball must be OLD SKOOL. Newer is not always better.
