Was playing basketball over the last 2 days and injured my knee again! I've injured my knee cartilage this time and my knee has been my biggest problem so far this year. Just when I just gotten the green light from my physiotherapist to go ahead doing sports, I immediately injured again on the 2nd day. Just saw my physiotherapist again and will be needing another few weeks for the knee to be better this time. Feeling really helpless and frustrated.
