Hi VickyS, im now eight months post op and just now generally feel like i am starting to regain some strength. I lost a lot of upper leg strength for quite a few months as was noticable when i was walking, using my bike but now feel like i'm slowly getting up to good (not full) strength.
I decided to take quite some time off work to recover and feel i made the right choice. It does take time but your fella will get there. I remember the feeling of having no strength and it's hard to understand how, why, what is going on and when you'll get back to normal, or as normal as can be.
Considering your fella is going to work he's already doing well, slow and steady is the way forward and he will get there. Onwards and upwards from here.
