The difference is @phideaux is you worked the knee and did everything to strengthen it and that is where you are ahead. Most sit and do no exercises and wonder why it isn't getting any better. I knew from what you said your recovery would be way ahead so I am glad you have good results but I know you did work for it too.
I think that's the key.
I am exercising really hard 2 times a ra everyday now , building all the muscles in both legs,
But concentrating on the right one.
It's work, but I do believe it pays off.
I also apply heat to the right knee 2 times a day for 30-40 minutes to create greater vascularity for better healing.
Then when I get home I will go on a very high protein diet for 3 weeks. At least 100 grams of protein a day.
Promotes healing. Of course I'll do all the painful rehab exercises.
By Christmas I'll be Superman.
