I dropped my walker on day 5, used a cane for 2 weeks after that. Im at the start of week 8 and have been walking without support since start of week 4 and walking my dog about 1.5 miles every morning. Some days walking 3+ miles. Measured 133 degree bend at my last PT yesterday and they advised not to bend further, lol. Obviously everyone heals and progresses at different paces. You are fairly young (comparatively) OP and while you dont want to overdo it, you really do want to push your level of comfort. You will get there. Dont be discouraged or let that bother you and its not healthy to compare your experience with everyone elses. Be smart, push yourself while listening to your body.
