I'm so happy I found this thread. I'm a young one, too - 38! Actually my first ortho kept pushing for 40 due to my age, but I was really having issues walking at all the week before last because I did something to my knee and then Thursday it locked up while I was walking to the breakroom to fix my lunch and I about hit the floor. I caught myself on the wall. I really couldn't walk then and was in so much pain.
I called my husband to come pick me up and to take me into the ortho emergency. I was told there was NOTHING they could do for me except the replacement. I was given a cortisone injection even though the PA didn't think it would help and it didn't. He did very quietly tell me it was time for a second opinion. I have a friend that is a PT and he recommended a few orthos, so I picked his favorite and went to see him. Apparently my knees are so craptastic I also have grooving starting on my femur and I really need to have the surgery soon. I was going to push it but have it done by year-end due to my deductible by my family staged an intervention and I'm scheduled on 8/4. I'm trying to get a feeling for how long I'll be out of the office and it sounds like it might be a bit longer than I planned.
