What causes pain in foot after knee surgery?
Patient: Since I had knee surgery and have been off my feet alot, the skin on my legs from the knees down has turned a mottled brown, only in the front of the leg all the way to the end of my foot. Do you know what could cause that? it doesn t hurt at all. Thank you Doctor: Hello,  As the knee is fine and there is no pain post surgery I think will be the discoloration of the skin due to vascular insufficiency. try doing hot water fermentation and do ankle toe movements. Usually, the skin discoloration doesn't happen in many of the cases. Taking a blood routine will also be good to see if any infection is causing the issue.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist
