I Have an ACL Injury and I’m Trying to Get Back to Running

Your knee may feel stiff, weak, or uncertain when you try running after an ACL injury because the knee may not yet be ready for the repeated demands of running.

Getting back to running after an ACL injury can feel very different from simply being able to walk without pain. You may take your first few jogging steps and notice stiffness, weakness, or a feeling that you are not quite confident putting weight through the injured knee.

You might also notice that the knee feels fine during ordinary daily movement but changes once you start jogging. The first few minutes may feel awkward, or your knee may become sore, tight, or less dependable as you continue, especially when you increase your speed or try to run for longer.

Your First Few Running Steps Feel Uncertain

Your knee may feel stiff or hesitant as soon as you begin jogging again.

You may find yourself taking shorter steps or holding back because the injured knee does not feel as natural as the other side. That hesitation can happen when the knee has lost strength and confidence during the time you spent away from running.

Your Knee Gets More Tired As You Run

Your knee may start out manageable but feel weaker or more uncomfortable as the run continues.

You might feel fine during a short stretch of running and then notice soreness, stiffness, or a less steady feeling as the minutes pass. Increasing distance or pace too quickly can make these symptoms more noticeable because your knee has to handle the same movement over and over without enough time to adapt.

Why Your Knee Still Doesn't Feel Ready For Running

Your knee has a hard time healing when blood flow and circulation are limited.

Tendons, ligaments, and other soft tissues naturally receive less blood supply than many other parts of the body. Because of this, they often take longer to heal after repeated stress or injury, leaving you more vulnerable to lingering pain and a cycle of reinjury.

When circulation through the area remains limited, injured tissues have a harder time receiving the vital oxygen and nutrients they need to repair and heal. This can leave your knee feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Knee Feel Better

Your knee starts feeling better when blood flow and circulation improve.

Chinese herbs have been used for centuries to promote healthy blood flow and circulation. Their medicinal properties help break up stagnant blood and fluids that remain trapped around injured tissues, interfering with circulation. As circulation improves, blood flows more freely through the area, allowing those tissues to receive the oxygen and nutrients they need to heal properly.

Topical herbal remedies made with these Chinese herbs can help relieve pain while improving blood flow and circulation to injured tissues. The right product depends on your symptoms and whether you're in the acute or chronic stage of recovery.

If you have pain, swelling, inflammation, or bruising, Acute Sinew Liniment helps relieve these symptoms by increasing circulation and dispersing stagnant blood and fluids around the injured area to speed recovery. During the acute stage of healing, getting circulation moving early allows injured tissues to receive the fresh blood, oxygen, and nutrients they need to repair and heal.

If your injured area is especially swollen, red, or warm to the touch after a recent injury or flare-up, Sinew Herbal Ice is also used to reduce swelling and inflammation while restoring normal circulation so you can quickly regain range of motion. While traditional ice is commonly used to reduce swelling, Sinew Herbal Ice acts as an ice alternative to reduce swelling and inflammation while also dispersing accumulated blood and fluids to speed the healing process.

If you no longer have swelling or inflammation, but still have pain, stiffness, weakness, or sensitivity in cold and damp weather, Chronic Sinew Liniment helps relieve these symptoms by strongly stimulating circulation and increasing blood supply to injured tendons and ligaments to promote their healing. This is especially important because tendons and ligaments naturally receive less blood supply, which is why chronic injuries can take longer to heal.

If you have residual pain and stiffness, or the area becomes more painful in cold weather, Sinew Injury Poultice is also used to significantly stimulate circulation to injured tendons and ligaments to further promote their healing. By strongly increasing circulation, it counteracts the reduced blood flow caused by cold weather that commonly aggravates chronic tendon and ligament injuries.

If you exercise, play sports, or do other strenuous activities, Sinew Sports Massage Oil warms and stimulates muscles for exertion and relieves muscle tightness and soreness after activity. Warming and preparing your muscles before activity can improve flexibility, enhance performance, and reduce the risk of injury.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

When can I start running again after an ACL injury?

You should return to running when your healthcare professional determines that your knee has regained enough strength, mobility, and stability for running.

Why does my knee feel stiff when I start running after an ACL injury?

Your knee may remain stiff because it is still recovering and may not yet tolerate the repeated movement of running comfortably.

Why does my knee feel weak when I try running after an ACL injury?

Time away from running can leave the injured leg weaker, making the knee feel less confident when you begin running again.

Yes. Returning too quickly can increase knee pain, swelling, stiffness, or instability before the knee is ready for running.

What should I do if my knee hurts when I return to running after an ACL injury?

Stop running and have the knee evaluated if running causes pain, swelling, or instability rather than gradually improving comfort.
