Thanks JK. Great that you had such good results, although 6 weeks of pain is a little frightening. At least it went away. I'm going ahead with Mako, not sure anyone in our area does Conformis - I just read yesterday that Stryker (which makes Mako) has struck a deal with Conformis to develop a custom knee that can be used with its robotic arm. The best of all worlds! But it will take a few years for FDA review and approval so I'm not waiting. Thanks again!
