Hello, I had R TKA July 28th. Immediately after surgery noticed foot numbness and foot drop. Surgeon ordered foot brace to wear so I didnt trip and fall over R foot. Initially nurses and surgeon said oh just need to wait for block to wear off. May retake 2 days, may take 2 wks. As of today there has been no change. Surgeon finally ordered MRI, EMG, NCS all to look for nerve damage. MRI did not pick it up but the other tests did. Surgeon finally admitted there was nerve damage. Today I will see the neurologist for her take on all this after she reviews all tests and looks at me. Lower leg and foot are very stiff. Atrophy of muscles setting in because damaged peroneal nerve cant communicate with leg muscles. Have been told it may take a year for nerve to heal but I've seen NO change in 3.5 months so hard for me to believe there will be any improvement. Nerve was damaged behind my knee. Hurts to rest knee on chair like when you sit and on seat of car to drive. Leg feels heavy cuz upper leg muscles need to do all the work to lift lower leg like when going up stairs or moving foot from gas to brake in car. Anyway, will see how neurologist sums things up today. Hope this was helpful. May be looking at litigation sooner than later...
