<s>[INST] Sir,I got my ACL&PCL injured in bike accident.Later after 6 months i got my knee operated by arthroscopy(bi cruciate surgery).It has been1 yr 8 months since i was operated,i am still not able to run..Walking is not proper.I underwent physiotherapy for few months in the beginning and later stopped doing.Please advise me what to do for getting normalcy.And do i need to get the steel screws (used in arthroscopy)removed now??i am depressed a lot.. Thanks a lot..Hanuman,India [/INST] Hi hunuman In my opinion removing the screw could help or not  depending on your knee x ray If you are able to carry a weight of 30 kg in knee extention , you will be able to run normal if you can carry 30 kg in extention and can not run properly then you need another surgery to tighten you acl, pcl ligaments Good Luck </s>
