I Had A Total Knee Replacement In Mar 2015. The

I had a total knee replacement in Mar 2015. The knee healed fine but I started having pain in a small area in the muscle towards the inside right knee. Pain starts 2"at the above knee and goes to my foot. I am preparing for surgery because: knee replacement has come off the knee and there is some type of infection that needs to be treatment; there is a hole in the shin/tibia, the pain is so bad. no pain meds have worked,
