You have said it well: the two extremes of rehab are protect the healing, or protect ROM. As you've read in my posts, my Mayo Clinic OS believes in three month healing period. Period. But, after four weeks, with two-piece cast, I began lifting leg at knee by adjustable braces. See him again this Thursday. He wants me at 45 degrees ROM. I will definitely ask him about more PT work, however. I'm guessing that both healing and ROM have to go hand in hand. But the timing is the variable.
