Actually, many knee surgeons are beginning to change to starting PT a couple or few weeks after the surgery while resting with ice and compression. I have an incredible surgeon who does exactly that and I came out not only with no post surgery pain but ROM in that third week of 122 and a flat extension.

By the way, current research is beginning to turn against the use of a tourniquet:

My incredible surgeon did NOT use a tourniquet using tranexamic acid instead.
