Feb 16th 2016. I had take on my right knee back in 2010 and I have had clunking and pain ever since. After having the original surgeon tell me that "it is what it is," I opted for a second opinion. Being that this was a workers comp thing, I had to pay for the second opinion myself, only to hear him say, it is what it is. 5 yrs afterwards, the original surgeon says that my ligaments have stretched and that I need a thicker spacer...soooo, I get pain meds for Valentine's....grrr
