My heart goes out to you. After numerous surgeries over the years (very athletic since little) I have learned one important lesson. Listen to your body! You live in it and you know what is normal and abnormal in it. I have learned that you must be your own advocate and not let the doctors intimidate you when you know something is definately wrong. Did you suffer the nerve damage before the surgery? If not, and it appeared after the surgery, your peroneal nerve was damaged during the surgery. That is the nerve that, if damaged, can cause foot drop. I had it happen a year ago after when I had my TKR in my hometown. Those full AFO braces are torture! My surgeon agreed that it was absolutely not helpful for me..a petite female athlete. My PT found me one one line that velcro's to my ankle and attaches to my shoe laces to pull my foot up when walking. Research them online. Amazon has some and so do other companies. Also, research possible treatments to help keep the foot from dragging. I have found a number of them, most involving minor surgery to treat the foot drop. I am planning to discuss with my surgeon and my neurosurgeon. I knew there was something terribly wrong with my TKR and my doc kept saying "your Xrays look great". However, Xrays do not show nerve, or soft tissue, ligament, etc damage. I was also told by my second opinion surgeon that the implant was to big for my size knee, the cement was not holding and thus the knee is very loose. I have consulted two additional well regarded knee surgeons and plan to have a revision surgery this Spring. We have been discusssing all the options.....custom knee, Stem cells, or conventional with robotic assist. I encourage you to research online, educate yourself, reach out to others (glad you found this forum, as you will learn you are far from alone due to complications) and schedule appts for consults with other surgeons you can discuss your issues in your area or go to a well respected medical faciltity that has a good reputation re: TKR surgery results. Finally, don't get discouraged and do not give up. You will find the answers and a surgeon who can help you.
