Pain on the Outside of Your Knee? Here’s What’s Causing It

Pain on the Outside of Your Knee? Here’s What’s Causing It

Why the Outside of Your Knee Hurts

If you feel pain, tightness, or aching on the outer (lateral) side of your knee, you’re not alone.
This type of pain is very common in adults over 50 and often shows up during walking, going downstairs, or after standing for long periods.

The outer knee absorbs significant stress during movement especially if there’s inflammation or muscle imbalance elsewhere in the leg.

Most Common Causes of Outer Knee Pain

1. Iliotibial (IT) Band Irritation

The IT band runs along the outside of the thigh and attaches near the knee.
When it becomes tight or irritated, it pulls on the knee, causing:

  • sharp or burning pain
  • aching during walking
  • pain that worsens going downhill or downstairs

2. Knee Arthritis

Arthritis doesn’t always hurt in the front or center of the knee.
Cartilage wear can create pain on one side — often the outer knee.

Symptoms include:

  • stiffness
  • swelling
  • grinding
  • pain after sitting

3. Meniscus Degeneration

The outer meniscus can wear down over time, leading to:

  • sharp pain
  • catching sensations
  • swelling
  • pain when twisting

4. Weak Hips or Glutes

Weak hip muscles force the knee to absorb more stress during walking and standing, leading to outer knee pain.

5. Poor Walking Mechanics

Subtle changes in gait or posture can overload the outer knee over time.

6. Old Injuries

Past sprains or falls may create long-term inflammation that resurfaces years later.

Why Outer Knee Pain Often Gets Worse

Many people try to “push through” the pain.
But without treatment, inflammation builds and causes:

  • more stiffness
  • reduced stability
  • worsening pain on stairs
  • limited mobility
  • increased risk of falls

Early intervention makes recovery faster and easier.

Signs Outer Knee Pain Needs Attention

✔ pain during walking or standing
✔ pain going downstairs
✔ tenderness on the outside of the knee
✔ swelling or tightness
✔ stiffness after sitting
✔ catching or instability

These are signs of joint inflammation not just muscle soreness.

Why Ice and Stretching Alone Aren’t Enough

Ice and stretching help temporarily, but they don’t correct:

  • inflammation inside the knee
  • cartilage irritation
  • muscle imbalances
  • poor circulation

Long-term relief requires targeted care.
