Foot neuropathy after total knee replacement

Posted by norby @norby, Nov 26, 2018

I had a right total knee replacement 10 weeks ago and came out of surgery with numbness and intermittent pain on the bottom of my right foot. However, I do have good motor function in that foot. The knee has been healing and with PT, movement is on track, but the foot is a major challenge. The foot pain at times is worse than any from the knee. I have been able to generally manage the foot pain with gabapentin. My surgeon believes this may resolve in time but may take from 6-12 months. However there is a possibility that it will never go away. Has anyone else experienced foot neuropathy following knee replacement? If so, what was your experience with it?

Hello @vinran, Welcome to Connect. I'm not very fond of the term idiopathic either which is my neuropathy diagnosis. I know all surgeries carry a risk and nerve damage is one I was worried about when I had my right knee replacement done. I also had lymphedema prior to the surgery and have to wear compression socks to keep the swelling down. Here's some information I found that talks about what I think you are describing.

"Can knee surgery cause swollen lymph nodes?
The secondary form may be caused by a lesion of the lymphatic vessels and/or lymph nodes during diagnostic or therapeutic procedures such as surgical interventions. Often, in clinical practice, there is lymphedema after orthopedic surgery, even in minor orthopedic surgery."
— Lymphatic edema of the lower limbs after orthopedic surgery: results of a randomized, open-label clinical trial with a new extended-release preparation: https://pubmed.ncbi.nlm.nih.gov/26753640/

Hopefully your next appointment can provide some answers for you. Can you provide an update after your appointment next week with the general surgeon?

I developed foot neuropathy about 6 mont(s after TKR, never had symptoms prior to surgery. I’ve seen neurologists, a vein surgeon,had an ECG and an
ultra-sound and doctors say everything is fine, but it isn’t. I’ve been prescribed Gabapentin which helps me sleep at night. Most neuropathy symptoms do appear late in the day or early evening. Symptoms are tingling in the bottom of my feet and a burning sensation. I’ve also Devoloped lymph node swelling at the top of my surgery leg in the groin area. Tests results indicate lymph node swelling but appear to be no abnormalities. I’m tired of the term “ideopathetic from all doctors I’ve seen. I am now referred to a general surgeon next week to assess my nymph lobe swelling. Disgusted here. Knee itself has been okay from a functional standpoint.

Saw a surgeon
He did a thorough exam and can’t find anything
that would be obvious to the cause of my groin lymph
swelling. He believes it is a result of the extensive TKR
I had and may take 2-3 years for the fluids etc in my leg to return to normal – I didn’t quite understand all of that but wants to have another ultra sound in 6 months and see where I am at.
That’s where I am at.
I mentioned the foot neuropathy issue as well and he said that’s not abnormal and may eventycorrect itself.
We will see
