Hi. My doc prescribed the donjoy Defiance (nice!) for me, and my insurance is allowing for a functional post-op rehab brace instead (an L -1832 model). This may mean that if I want the lighter brace for actual sports and real activities I have to pay for it on my own (not sure on that front, I will fight it). I'd love to hear any feedback about the efficacy of the post-op braces. I'm nearly 4 weeks post op and am weaning myself off of crutches. I've been without the immobilizer for about a week, and I have full extension and most flexion back. Hoping to get back to jogging, cycling, hiking, and even skiing as the year progresses. Any guidance is much appreciated.
