How to Keep Your Feet Healthy and Soft?
May 1, 2025If you’ve got knee and ankle pain, you need to know that these two are connected. People often try to treat just one joint. But your knees and ankles work together. When your ankle doesn’t move the right way or feels weak, your knee starts picking up the slack. And when that happens, pain follows. Let’s break the relation between knee and ankle pain completely.

ToggleAre Knee and Ankle Pain Related?
Yes, knee and ankle pain are very connected. Your ankle, knee, and hip are part of a movement chain. They are like gears in a machine. When one gear slips, the rest start grinding.
Let’s say your ankle is stiff or turns too easily. That changes how you walk. Your knee ends up twisting or bending in ways it shouldn’t. This can cause pain right under the kneecap or along the inside of the knee. Foot and ankle specialists say that this extra pressure wears things down over time.
A research study in 2022 found that patients with chronic ankle instability were 2.5 times more likely to say they have knee pain. That’s not a small number. This happens because your knee starts to twist or shift in ways it’s not supposed to, just to make up for your ankle.
People who’ve had an ankle sprain, or even just weak ankles, often don’t realize how much their knees are paying for it. A past injury might seem healed, but if your ankle feels wobbly, your body is still trying to make up for it every time you take a step.
Here’s something else: when your knee is the one causing trouble, your ankle can start to move differently, too. Maybe it rolls out or in, or maybe your foot hits the ground harder. Either way, the ankle ends up doing work it wasn’t built for. That leads to soreness, tightness, or sometimes more injury.
In a nutshell, knee and ankle pain are connected! When your ankle moves wrong, your knee has to do more. When your knee moves wrong, your ankle suffers. It goes both ways.
Potential Causes for Related Knee and Ankle Pain
| Cause | What It Means |
| Flat feet | Makes ankles roll in, knees twist |
| Weak ankles | Makes knees work harder |
| Previous sprains | Can leave ankle unstable |
| Poor footwear | Doesn’t support joints |
| Arthritis | Makes joints stiff and painful |
| Tight calf muscles | Limits ankle motion, stresses knees |

Instability of Knee and Ankle Pain Treatment
The goal is to treat both your weak or painful ankle and knee together. Here’s how foot doctors Mesa do it:
Physical Therapy
A therapist builds your strength and balance. You’ll do exercises that stretch tight muscles and make weak ones stronger. For example, you might do ankle rolls, calf stretches, or gentle squats.
Custom Orthotics
These shoe inserts help your ankles stay in the right position, which keeps your knees lined up, too. They are made by looking at how you walk and then creating a support that fits inside your shoe.
Bracing
Foot doctors may give you an ankle or knee brace to wear during the day. This keeps your joint from moving the wrong way. Braces give extra support while you heal and help prevent more injury.
Manual Therapy
This hands-on treatment could be gentle joint movements or soft tissue massage. If you have stiffness, scar tissue, or tight muscles, this helps loosen things up and improve motion.
Anti-inflammatory Treatment
For swelling and pain, podiatrists Gilbert might suggest over-the-counter meds. If that doesn’t help, they may offer a cortisone shot to calm things down. You can often use it when your pain is strong and stops you from moving.
Can Ankle Injuries Cause Knee Problems?
Yes! Injuries of your knee and ankle pain are connected.
- A sprained ankle can change how you walk and strain your knee.
- Torn ligaments can make your knee try to balance for the ankle.
- Achilles tendonitis affects how your foot pushes off which hurts knees.
- Fractures can lead to long-term walking changes.
- Chronic instability makes your knees work too hard to keep balance.
How Do These Injuries Affect You?
When you hurt your ankle, you might start limping or turn your foot outward. Podiatrists Chandler say that this puts stress on the wrong muscles and causes your knee to twist or bend in ways it shouldn’t.
Over time, this can cause sharp pain in the knee, especially when going up stairs or getting out of a chair. It also tires you out more quickly because your muscles are doing extra work to keep you upright.
How Should Your Ankle Move?
Your ankle should move forward, backward, and in small circles without pain. It should bend when you walk and let your heel touch first, and your toes last. This smooth motion helps your knee stay straight and strong. Knee and ankle pain starts when your ankle is stiff or turns too much.
Top Limited Ankle Mobility Causes
| Cause | What It Means |
| Old ankle sprain | May leave behind tight scar tissue |
| Tight calf muscles | Stops the ankle from bending forward |
| Arthritis | Makes the joint stiff and swollen |

| Poor posture | Throws off body balance |
| Bone spurs | Extra bone blocks movement |
