Hi, 4 months ago I had meniscal repair surgery, went back to sports, everything was fine. The other day, I squatted down and got a sharp pain in my leg so bad I could straighten my leg or walk, went to emergency, they thought I retore my meniscus. Now wearing a huge knee brace and crutches. 3 days later, have full range of motion, but still severe and constant pain in side of knee. Can walk on it for short periods of time but hurts. Should I still use crutches and do you think it was another medial meniscal tear?
