I had TKRs on both knees this year. The surgeon used the Mako robotic assistant.

The first surgery in March was fine. Swelling came down, motion came back, and it felt like I was fully recovered in six weeks. Second surgery was in July. Motion came back but slight swelling has been stubborn. Pain in both knees is gone.

But the skin around my knees and part way down my shin is numb, or at least somewhat numb. Surgeon said that is normal and feeling may come back, may not.

So while this is nowhere near the problem you are having, like you, I wasn't warned in advance of this. It seems like some type of nerve damage, and personally, I don't hold out a lot of hope that this will change.

But I do hope your foot gets better. Not being able to touch your foot or put on a sandal is ridiculous, especially if you weren't warned that this is a possible side effect.

All the best to you. Joe
