Yes, Ive had several knee ablations post-TKR. They are painful but you can drive after. I have to admit that they only helped me with about 30% of my pain for a couple of months- no where close to 6 months. After 4 per knee I have taken a break to see if I notice a big difference. They dont help with the tightness I have (24/7) . They help a bit with the sharp pain I have when walking. Not sure yet if I will try again.
