Hello! I currently have no hip joint or spacers. My hip replacement got infected then removed about a year and a half ago and with exercise I am able to walk with out a crutch. Of course I have a limp cause there’s about a 3 -3 1/2 inch length difference. I use a cane in public to help with the limp. But I can ride the bike walk up stairs it just took some work to get to this point but it’s possible!
