I am 38 years male, I got an accident last year when I was riding bike, I got severe pain in my left leg which was last for 3-4 days, I consult a doctor (orthopedic) who suggest me MRI and MRI reveals that I got ACL ligament injury, after that he put bandage around my leg which had a belt which keep my leg straight for one week, after that things got better day by day, now I can walk, sit and squat without problem but can not bend my knee, MRI also reveal meniscus tear. Please tell me do I need operation? I have no problem in running, stairs climbing walking etc. Thanks a lot.
