@marytabor some suggestions: your husband can practice getting up from chairs and out of bed without using his arms before surgery. Get a power recliner or lift chair for your husband.

I was 72 when I had surgery and I was probably not as overall physically fit as your husband, but my legs were strong from bike riding and walking stairs. I was able to get out of the hospital bed unassisted from the day after surgery. I also slept in my power recliner for about the first month after surgery because it was more comfortable for me than the bed.
