Do you stand a lot at work? It’s really early to have to stand a lot. Even after I was able to do some decent walking, it took a lot longer to be able to just stand still for any length of time.
I hope you are able to ice and elevate when you get home from work. I elevated all night long, and actually I still do.
Recovery from any knee replacement, partial or total, takes a full year for complete healing. That was a shock for me to learn, as I had read glowing reports of a quicker recovery for a partial. I expected a 2-3 month recovery. I’m 2.5 years post op and still in recovery mode, in many aspects. I’m not happy at all with my outcome.
