I am a year out from surgery and still have clicking in my knee, although not every step. I think it is permanent at this point. Also have numbness down inside of calf. It has gotten better but still there. Hopefully it will dissipate over time. And have numbness near the the incision which is normal because they have to cut a lot of nerves for this surgery. That is permanent but doesn’t bother me. Bigger issue is ongoing pain on outside of kneecap when put weight on it or bending it. To have bone scan to check for infection, allergies to cement and/plastic. You are very early in recovery so you have lots of time to improve.
