Anterior Cruciate Ligament (ACL) - Anatomy and Function 

Rui, I'm sorry to hear about your injury. Usually people can walk after an isolated ACL tear. There is initial pain, swelling, fluid in the joint (effusion), difficulty with motion etc. Over time these tend to improve and patients start to feel better and can walk. However, there are situations where the knee can get very stiff and make walking difficult. You mentioned you had a meniscus tear. Certain patterns of meniscus tears could cause a block/restriction of your knee motion. I would seek to reach out to your physician and have a quick check to make sure things are ok. Typically, we will start patients on a "pre hab" program prior to surgery which helps improve the knee swelling, motion, muscle strength which has been shown to help recovery after surgery. Best of luck! ___________________________________________________________________________ Please understand that this does not represent the formation of a formal doctor patient relationship and is for educational purposes only.
