I tore a piece in my late teens. I had to spend two weeks waiting for surgery, without being able to straighten or fully bend my knee, it was locked at about 30 degrees. They removed the piece arthroscopically. I will notice it if I do a long day of walking, it will get sore. When it was done, they said knee replacement was probably in my distant future. The knee I had surgery on, actually has better range of motion than the other knee, and doesn't bother me unless I'm all day hiking or hunting, or 10 minutes shopping. It will be sore the day after. Walking to keep the muscles strong, helps me. Do the physical therapy, it will make it heal faster, pitching the crutches was a good thing, get up and get back at it. Hope you have a speedy recovery.
