Had my right knee replaced 4 years ago with a Stryker Triathlon joint. So far so good. I will be doing my left knee soon and I was looking into the Conformis system. Its supposed to be designed from a CT scan of your knee area to match your bone structure perfectly. I am asking if anyone here has had this done to them and any pros and cons with this. I had an issue with my old OS and I am moving on so I am doing my research all over.
