I injured my knee three weeks back & had my MRI done 10 days back &
all doctors & analyst suggest that I have a probable tear of my ACL
(Anterior Cruciate Ligament). Although I have fixed an appointment
for it grafting surgery next week but I have some doubt.

My leg movement has been improving since the date of my injury.
Although it made a loud crackle noise during my injury & had swelling
in the knee but I never had any pain in my knee unless I fold it. It
does pose some instability while moving around.

Dr. was suggesting he would be sure of complete tear of the ligament
only during the surgery. My question is, Is there any process by
which I can check for the condition of my ACL before actual surgery?
