Hi all ive had 2 op on my left knee, 1st one (may03) to repair my damaged cartlidge, 2nd one (dec03) to found out why im in so much pain, the surgeon told me that my pcl has wasted away and I no longer have one, he dosnt want to reconstruct it as he says the rest of my knee is ok and its too risky, is this as bad as it sounds? Is more surgury the answer?
