Hi I had a right total knee replacement about 8 months ago and had numbness right away to the heel and right half of the bottom of the foot including my 4 and 5 baby toe
I asked my surgeon about it and he couldn’t explain why just that it can happen . He said it will take a while to improve and said the nerve comes back about a millimeter a day . I have had improvement but my heel has less feeling and my toes are over sensitive so I choose my shoes carefully and I am totally back to all activity as tolerated I have just found that the calf gets tired quickly and have to just work through it on walks . I did take nortryptiline for nerve pain instead of gabapentin less side effects and only needed it for a few weeks . My best advice is after 4 weeks get into physio in the pool. Walking against current in a lazy river and doing lunges etc. feels so much better than at physio . I was kicked out of physio at 6 weeks for doing to much but I still do the pool I will check back in a bit and let you know if the numbness resolved by 12 months or not . One recommendation is to get a crocus for the knee post surgery. Here in Canada it is mandatory to bring with you and it goes on right after surgery I used it all the time I was resting and it helps with the pain tremendously about 200 dollars. It is like Cooler filled with ice and water and it pumps through the knee cuff and doesn’t have a time limit like ice it is just circulated cold water
