<human>: My partner had a total knee replacement 4 months ago and is now experiencing a stinging/burning sensation on his kneecap near the scar. This is causing him a lot of pain and hindering his walking. Do you know what this could be and if you do is there anyway of easing it for him. Thank you.
<bot>: That can be a sign of neuroma formation meaning a superficial nerve that supplies sensation to the skin is cut during the surgeries not a complication, and sometimes it cannot be avoided during the surgery procedure what you have is this infrapatellar branch of saphenous nerve injury after total knee arthroplasty pregabalin 75 mg once a day this is specifically for nerve pain can be tried but sometimes it can cause mild sleepiness
