Can you still walk with a torn ACL 2024?

As a medical professional with a focus on orthopedics, I am often asked about the consequences of a torn ACL, or anterior cruciate ligament. The ACL is a crucial component of the knee joint, serving as a stabilizer that connects the femur, or thighbone, to the tibia, or shinbone. Along with other ligaments, it plays a vital role in maintaining the stability and alignment of the knee during movement, especially during activities that involve running, jumping, and sudden changes in direction.

When an ACL is torn, it can range from a mild sprain, where the ligament is stretched but not completely ruptured, to a complete tear, where the ligament is severed. The severity of the injury can greatly affect the symptoms and the ability to walk or perform other physical activities.

In the case of a complete ACL tear, the knee joint becomes significantly loose and unstable. This instability is due to the loss of the ligament's function in preventing excessive forward movement of the tibia relative to the femur. Walking with a completely torn ACL is possible, but it is not advisable for several reasons:


1. Instability: The knee may feel unstable, as if it might give out during weight-bearing activities. This can lead to a lack of confidence in the leg and an altered gait pattern.


2. Pain: There may be significant pain, especially during activities that involve bending or straightening the knee.


3. Swelling: The knee is likely to swell due to the injury, which can further limit movement and increase discomfort.


4. Risk of Further Injury: Continuing to walk or engage in physical activity with a torn ACL can increase the risk of additional injuries to the knee, such as meniscal tears or damage to the other ligaments.


5. Long-Term Consequences: Ignoring a torn ACL and not seeking treatment can lead to long-term issues, including arthritis and chronic knee problems.

The treatment for a torn ACL typically involves a combination of rest, ice, compression, and elevation (RICE) in the initial stages, followed by physical therapy to strengthen the muscles around the knee and improve stability. In some cases, especially for individuals who are very active or participate in high-impact sports, surgical intervention may be recommended to reconstruct the ligament and restore stability to the knee.

It is important to consult with a healthcare provider or an orthopedic specialist to determine the best course of action based on the severity of the injury, the patient's activity level, and overall health. Attempting to walk or continue with physical activities without proper assessment and treatment can exacerbate the injury and lead to more serious complications.

The ACL connects your thighbone to your shinbone. The ACL, along with other ligaments, keeps your knee and leg bones in place when you walk or run. When a ligament is injured, it can be stretched, partially torn, or completely torn. Complete tears make the knee joint very loose and unstable.
