Don't worry about how soon you give up crutches. I was still using them at 6 weeks after all of my TKRs. You'll know when you're ready to manage with just one, or a cane. It happens gradually and it's much safer to keep using them than to risk a fall.
The problem with many people (probably that includes your mother) is that they don't realise that recovery from an orthopaedic operation is often a slow process. They expect you to be "all better" by about 6 weeks, possibly as they have felt after an abdominal operation. Bones, ligaments and muscles take longer to recover than your skin does.
Try not to let it get you down. Good things take time.

I really wish your family had a better understanding of your recovery issues and recovery time frame; aarrggh! What will it take to get through to them? Perhaps your OS or PT could write something up for you to hand them, explaining in simple terms what your recovery will look like. They all need their unrealistic expectations adjusted, and right now, you're vulnerable, so that's a very difficult place for you to be in. I honestly think your husband and mother should accompany you to the OS office for a recovery chat. Maybe they will believe him/her. In the interim, just stay behind your pillow fort!
