I got acl surgery a month ago and i was wondering how long till i can put pressure on it or walk?

Ask your surgeon...: For a copy of their protocol. This answer depends on several things: 1) surgical technique, 2) meniscal status, 3) quad control. 4) pain, 5) swelling. Your therapist and surgeon will be able to help you figure out what is best for you. Note that any meniscal repair may slow your ability to put weight on your leg to protect the repair, but is worth it in the long run (prevent arthritis).
