Hi Jo,
I agree with all the others. Take your time, don't compare and add activity cautiously as you go. You will see what works and what doesn't.
I never went out for a walk per se, I went to the grocery store at first with my hubby, pushed the cart instead of using my crutches and tried to stretch out my strides. Short trips at first, but longer over the next few weeks.
Honestly for me, my recumbent bike has been the best. I was able to get a full rotation only after three weeks, and have never looked back since. I started slowly, then added more minutes as my stamina improved, then started adding resistance once I felt stronger. I am on the bike now everyday for at least 25-30 minutes and have the resistance up to about half. Now remember I am 5 1/2 months post op, so this seems right for my recovery. If I don't get on the bike for some reason, I feel tighter all day.
Also, I used one crutch for 3-4 months. Many others have had the same experience, TarHeel for one. I needed it for stability and because my limp was so bad. After the MUA, I went to a cane, and then shortly after no aid. I felt like a big failure having to use the aid for so long, but that was my recovery and need.
You are still early in and have been doing well by all accounts. Keep the patience mantra going and look ahead to better days. They will come, it will take time, but you will arrive. For me, it was like a switch got flipped and boom, no more cane, felt stronger and more clear headed, stamina and concentration returned, pure joy! That took me 4 plus months.
Keep posting your progress and we are all with you on your journey!
