In the news today:UniSpacer May Delay TKR for Patients with Early OsteoarthritisI was evaluated by two different physicians trained in the Unispacer procedure. Both agreed I was a good canidate. I had it done 10+ months ago and trust me it has not been fun. Some days are better than others, but today it feels like there is a rock in the joint. I have never been free of the feeling of something that shouldn't be there is in there. Will I have it in place for 10 years? I don't know, I keep hoping it will improve to the point I don't have pain with each step.
