Hello, As mentioned you been facing issues with weakness and spasticity of the ankle I think it s not the case you mentioned in the history. Clonus - it s a higher motor function controlling and just by the ligament of the ankle this can not happen. Spasticity - this is also a higher motor function controlling and not the ligament connection. Hyper reflex - I think you meant by this is that the plantar reflex is having hyper tone. So this is also the Higher motor function and nothing to do with the ligament. Did you mention about scans in history? Were you talking about the MRI? Have you taken the MRI of ankle or the brain? If of brain than what did it reveal in the higher centres of brain? and if ankle than what did it reveal about the internal structures of the ankle? you even mentioned about the test? what tests have been done? blood? urine? I don t think surgery of ligament makes any sense over here with respect to the symptoms you mentioned. The symptoms you mentioned are of higher motor functions in the higher centres of the brain. I will recommend you to meet up a neurologist rather an orthopedist. A neurologist will be the right person to guide you. Coming back to clonus, spasticity and weakness. There is a therapy plan which you can try out and that is using a balance board rehabilitation program under a guided neurophysical therapist. Hope you will feel better. But I will still insist that you meet up a neurologist and have a word. this will reduce your worries. Hope I have answered your query. Let me know if I can assist you further.
