Hello, 你好 可以讲一下膝盖运动创伤后的锻炼吗?my left knee has ACL& MCL tears after 滑雪. I took a class in Gym today this morning, a lot of exercise on legs. My left knee really hurts after class and it’s hard to get up in the afternoon till now. And same thing happened about one month ago,swollen to my back of knee, felt like 拳头大小在膝盖后面.
