Why Can't I Put Weight On My Knee After Twisting It While Running?

Your knee suddenly won't support your weight after twisting during a run because the twist may have injured a ligament, meniscus, or other stabilizing structure inside the knee.

You may remember the exact moment it happened. Your foot stayed planted while the rest of your body turned, or you stepped awkwardly on uneven ground. Right away, your knee may have felt sharp, unstable, or as though it could no longer hold you up.

Sometimes swelling appears within minutes, while other times the knee mainly feels weak and unreliable. Whether or not you heard a pop, difficulty putting weight on the leg after a twisting injury is a sign that the knee may have been injured more than just temporarily strained.

The Knee Feels Like It Will Give Out With Every Step

You may feel like your knee cannot be trusted the moment you try to stand.

Twisting injuries commonly affect the ACL, MCL, or other stabilizing ligaments. When one of these structures is injured, the knee can feel wobbly or unstable, making even a few steps difficult because your body no longer feels confident loading the joint.

Sharp Pain Stops You From Putting Weight Through The Leg

You may instinctively lift your foot back off the ground because every step hurts.

A torn or irritated meniscus, a significant ligament sprain, or damage to the joint surfaces can create sharp pain whenever you try to bear weight. The pain often feels worse when turning, straightening the knee, or trying to walk normally.

Managing Tissue Stress, Circulation, and Recovery

Pain that keeps returning during movement, after activity, or once the body cools down often means the injured tendons, ligaments, muscles, or nearby connective tissues are still recovering from repeated strain. When an area stays tight, restricted, or painful with normal movement, the tissues may not be moving or recovering as smoothly as they should.

Repeated stress can also leave circulation slower around the injured area, making it harder for oxygen, nutrients, and excess tissue fluids to move normally through the tissues. Over time, this can leave the area feeling stiff, weak, tight, or easier to aggravate during repeated movement and activity.

Topical Recovery Support

For acute injuries with pain, swelling and inflammation, some people apply Acute Sinew Liniment to help relieve pain, reduce swelling and inflammation, and increase blood flow to injured tissues to support faster recovery and a quicker return to activity. Some also use it alongside Sinew Herbal Ice to help speed up the recovery process and restore normal circulation and range of motion.

For ongoing pain, stiffness, or slow-healing areas after swelling and inflammation have subsided, some people apply Chronic Sinew Liniment to help relieve pain, stimulate circulation, and support recovery in overstretched tendons and ligaments. Some also pair it with Sinew Injury Poultice to further stimulate circulation and support deeper tissue recovery in areas with persistent pain and stiffness.

To warm up muscles, reduce tightness, and improve flexibility before or after activity, some people apply Sinew Sports Massage Oil to help increase circulation, prepare muscles for movement, relieve tightness, and support flexibility after activity.

Frequently Asked Questions

Should I keep running if I can't put weight on my knee?

No. Stop running immediately. Continuing to run could worsen a ligament, meniscus, or joint injury.

Is it serious if my knee twisted but I didn't hear a pop?

Yes. A significant knee injury can occur even without a popping sound if you cannot bear weight or the knee feels unstable.

Why does my knee feel like it will buckle?

A twisting injury can affect the ligaments or meniscus, making the knee feel unstable when you try to stand or walk.

Should I go to urgent care if I can't walk after twisting my knee?

Yes. Inability to bear weight after a twisting injury should be evaluated promptly to rule out a serious injury or fracture.

Will a twisted knee heal on its own?

Mild sprains often improve with time, but severe pain, swelling, instability, or inability to bear weight should be assessed by a healthcare professional.
