Well..... I had my meniscus surgery on the 26th of April. Only used the crutch the first day. Could get it straight and a great bend right away. It was doing terrific until a week ago. I was walking about a mile every day at a good clip and riding on my recumbent bike for 25 minutes in the mornings. Last Tuesday I rode my bike for 25 minutes, I got off walked across the house and my knee got really tight and then popped when I took another step after standing still for a few. It is hurting all over again. I will have to call my ortho tomorrow and make an appointment to see what I did!
I hope you can get it working great here really soon. Seems that it's taking too long!
