Yes, many people can still walk with a torn ACL, but it is often painful and the knee may feel unstable. Walking normally does not mean the ligament is okay, and it can still be completely torn.
What usually happens
Right after the injury, pain, swelling, and loss of motion often make walking difficult or impossible, so crutches are commonly needed. After a few days or weeks, once swelling and pain decrease, many people are able to walk in a straight line and sometimes climb stairs, especially if there are no major additional injuries.
Why it can be risky
The ACL is a key stabilizer of the knee, and without it the joint is more likely to “give way,” especially with turning, twisting, or pivoting. Continuing to walk and be active on an unstable, ACL‑deficient knee can increase the risk of damage to the meniscus and cartilage and raise the chance of developing early arthritis.
What you should do
If you suspect a torn ACL, it is important to stop sports or high‑demand activity and get evaluated promptly by a medical professional (urgent care, sports medicine, or orthopedics). They may recommend bracing, crutches, physical therapy, and possibly surgery, depending on your age, activity level, and how unstable the knee is.
Safe walking guidelines
Until you are seen by a clinician, it is safer to:
- Avoid pivoting, sudden direction changes, squatting, or jumping.
- Use support (crutches, cane, handrail) if the knee feels like it might buckle.
- Ice, elevate, and limit weight bearing if walking increases pain or swelling.
If your knee is locking, giving way with simple walking, or you cannot bear weight at all, seek urgent in‑person care.
