Patient: A year and a half ago kickball injury has not been treated, recently the film found ligament rupture, hello, my left knee anterior cruciate ligament rupture, I heard that we must operate to treat, the family is very worried, I do not know whether the risk of surgery is big????? Will I be able to recover after surgery? I need your help urgently. Hospitalist: Also a soccer fan, I am very concerned about your knee injury. If it is determined that there is a cruciate knee ligament injury, you should consider early surgery. The surgery family must be very worried. I need to tell you that arthroscopic ACL reconstruction surgery is a very mature and minimally invasive surgery with good safety, so please don’t worry too much. Please keep me informed of your thoughts. Patient: Hello doctor, I’m bothering you again, I have a question for you, did I break one or two bundles of my ACL? Thank you! Hospitalist: Thank you for the basket of flowers, I’m glad you’ll recover soon. Patient: Hello, I am now seventy days after ACL reconstruction of the left knee, the degree of knee swelling has significantly reduced, walking is also normal, but walking for a long time the knee is still a little reaction, the muscles of the thigh or some atrophy (compared to before or much better), as for exercise I exercise every night for an hour, after exercise will feel more relaxed, here a little confused is my meniscus injury The rehabilitation will not have an impact on my future life, right? How do you feel about my recovery now, Dean? Can I ride a bike at school? Thank you. If I have time, I will go back to you for a review during the November holidays. Hospital experts: I feel that your recovery is normal, muscle atrophy with the recovery of motor function will gradually get better, you can ride a bike, but pay attention not to fall down and get injured, you can swim, jogging and cycling activities, can not participate in confrontational sports, including playing badminton, as for meniscal injury will not affect your future life. I wish you a speedy recovery.
