Hello Doc., i am Avinash from Hyderabad, i am 22 yrs old and my weight is around 90kg with a height of 6.1.When i was playing football 3days ago i fell down (i was kicking the ball with my right leg in the air by balancing my body on the left leg), it was paining a lot so i went to hospital , as i already had a ligament injury to the same leg 3 years ago doctor suggested me a MRI Scan so i took a MRI Scan and i got the reports.The Reports Say two points in medical words they are 1) Chronic Complete Tear of Anterior Cruciate Ligament. 2)Radial Tear of Lateral Horn of Lateral Meniscus. when i consulted a doctor here he suggested me to take up an operation ,where they would re align the ligament settings. So 1) Is it really necessary to operate my knee? 2) Is it only the treatment or do i have an alternate? 3) If i operating the knee could my knee become normal ? 4) Is their any chance of me not getting any problem with my ligament of that knee?
