What is the need for two surgeries for a total knee replacement?
Patient: hello my name is Ross, I am 51 year old male, and I m to have TKR surgery next week, they told me that now I may have to take up to two different surgeries, because I have two screws put in when I had ACL surgery back in 1993. I m not really understanding why they need to have 2 separate surgeries now? Doctor: Hello,  We have to wait few weeks after screw removal and only after we can go for knee replacement. So two surgeries are required but screw removal is a simple procedure compared to TKR.  Hope I have answered your query.  Let me know if I can assist you further.
