I Had A Total Knee Anthropology 2 Years Ago And

I had a total knee anthropology 2 years ago and from day one of my post op recovery my quad was in almost constant spasm. I had 29 physical therapy visits, 5 acupuncture treatments, and 10 deep massage treatments. Everything afforded relief for a few days. Muscle relaxants didn't help at all. I read on the internet about Botox injections. Will that help, and for how long. My quad gets so tight and it feels like it is pulling on my kneecap.
