Right leg----they stitched my Torn meniscus and acl was not done..they said acl was good inside with partial tear...so only meniscus was done.. 2.left leg-----after putting scope they said no severity in my left leg...so it was not repaired and remain as it is now i am on my rehab with quadriceps exercises for both legs.... What is my recovery period.. After how many weeks i can able to use staircase.. How many months it will take me to drive an normal weighted two wheeler... I am really worried about my future as i am not an sports person...when can i again do an normal desk job and can able to do normal household works... this bed rest is depressing about my future
