Hello...It has been 1 year since my Girdlestone surgery in Feb 2022. I was in hospital for 3 weeks and when I left hospital, I could walk a short distance with a standard walker. At about 2 months I could get around with crutches some and learned to go up and down a few steps with them. It was probably 5 months before I could use a Rollator Walker at a more normal pace. I do a lot of exercises daily to build up my Quadricep muscles although I lost part of one Quadricep, IT Band and part of Gluteal Muscle in surgery due to severe infection. I can take a few steps by myself the past few weeks, but it's not pretty. I can get around good with crutches and forearm crutches and working on using just a cane these past few months, but haven't mastered that yet. I mostly use the rollator in the house and crutches when I go out. I do ride an upright exercise bike daily the past 2 months. I'm up to 10 miles a day and I've walked on treadmill a little bit holding onto to the bars. Scar tissue will fill in the empty space where there is no joint. My leg is 2-3 inches shorter on that side and my husband has glued old soles on my shoes to bring the height even. A lift inside your shoe is not enough. I really don't have much pain at all anymore. Just take Tylenol Arthritis pain med once or twice daily. I'm 70 years old. If your Mom didn't lose any muscle like I did, she may do even better than me when it comes to walking. It's a slow process and takes dedication, but it will continue to get better so tell her not to give up! Wishing your Mom all the best......Cindy
