Had the 6 week checkup. 0 degrees extension (that's full extension as I understand it) and 130 degrees flexion. These are normal or better, again, as I understand it. Doc cleared her for all activities, including aquaerobics, bicycling and traveling. When she went into the Doc's office, he said, "What, no cane and no walker?" She still has some swelling if she works out too much, and some nerve regeneration pain, etc. at which time she must ice and elevate. But, overall, she is doing great.
