WWE Smackdown star Rey Mysterio currently has no plans to have surgery on his knee according to ProWrestling.net.
It was reported back in the beginning of 2010 that Mysterio would work through his knee issues until WrestleMania, and then have surgery after the big PPV. When that did not happen, the feeling was that he would hold off until after SummerSlam to have surgery. That has not happened either, and instead it's being said that Mysterio had cartilage injections awhile back to help with the pain.
