I can use my new knee to go up and down steps, but it is a little stiff and sore to do. Ten days to go and hopefully there will be some improvement before then. I feel like for the last few days my progress is stuck. My old knee is giving me problems now that I am walking more and not doing a lot of medicating. As far as walking goes, the old knee gives me more trouble than the new one. Had my preop visit today with my PCP and my EKG was good. Don't know about the blood work yet, but should be good. Preop hospital visit on the 20th, and have my next followup for the new knee on the 22nd. Having another ConforMIS.
