When your leg hurts specifically when you walk and bend it, especially around the knee, it often points to issues related to overuse, muscle imbalances, or structural problems within or around the knee joint. This type of pain is commonly associated with conditions like patellofemoral syndrome, patellar tendonitis, or iliotibial (IT) band syndrome, all of which are frequently exacerbated by activities involving repetitive knee bending and weight-bearing.
Understanding Common Causes of Leg Pain When Walking and Bending
Pain that occurs during walking and bending can stem from several common conditions affecting the knee and surrounding structures. Identifying the exact location and type of pain can help narrow down the possibilities.
1. Patellofemoral Syndrome (Runner's Knee)
What it is: Patellofemoral syndrome is a common condition characterized by a dull ache in the front of your knee, around or behind the kneecap (patella). It occurs when the patella does not track smoothly in the groove at the end of the thigh bone (femur) during knee movement, leading to irritation.
Why it hurts with walking and bending: Activities that involve repetitive knee bending, like walking, running, climbing stairs, or squatting, increase the stress on the kneecap and the underlying cartilage. This can lead to pain as the kneecap rubs abnormally against the femur.
Common Symptoms:
- Dull pain behind or around the kneecap.
- Pain that worsens with activity, especially going up or down stairs, running, or prolonged sitting with bent knees.
- Grinding or popping sensations in the knee.
For more information, you can refer to resources on Patellofemoral Pain Syndrome.
2. Patellar Tendonitis (Jumper's Knee)
What it is: Patellar tendonitis involves inflammation or degeneration of the patellar tendon, which connects your kneecap to your shinbone. It causes burning and pain in or at the base of your kneecap. This condition is often seen in athletes involved in jumping sports but can affect anyone who frequently stresses the patellar tendon.
Why it hurts with walking and bending: The patellar tendon is heavily involved in extending the knee. Walking and bending the knee put direct tension and stress on this tendon, especially during the push-off phase of walking or when squatting, leading to pain and discomfort.
Common Symptoms:
- Burning pain just below the kneecap, often at the point where the tendon attaches to the kneecap.
- Pain that increases with activity, especially jumping, running, or squatting.
- Tenderness when pressing on the tendon.

3. Iliotibial (IT) Band Syndrome
What it is: Iliotibial (IT) band syndrome is an overuse injury of the connective tissue that runs along the outside of your thigh, from your hip to just below your knee. It causes burning pain outside of your knee that can spread to your hip or thigh. This occurs when the IT band becomes tight or inflamed, often due to friction over the bony prominence on the outside of the knee.
Why it hurts with walking and bending: As you walk or bend your knee, the IT band slides back and forth over the lateral femoral epicondyle (the bony bump on the outside of your knee). Repetitive friction can cause inflammation and pain, particularly noticeable during the mid-stance phase of walking or when the knee is bent at about 20-30 degrees.
Common Symptoms:
- Sharp or burning pain on the outside of the knee.
- Pain that often begins after a period of activity and worsens with continued walking or running.
- Tenderness to touch on the outside of the knee.

Comparing Common Causes of Leg Pain
To help differentiate between these conditions, here's a quick comparison:
Condition | Primary Pain Location | Type of Pain | Aggravating Activities |
---|---|---|---|
Patellofemoral Syndrome | Front of the knee (around/behind kneecap) | Dull ache | Walking, running, stairs, prolonged sitting |
Patellar Tendonitis | Below the kneecap (base of kneecap) | Burning, sharp | Jumping, running, squatting, walking |
Iliotibial Band Syndrome | Outside of the knee (can spread to hip/thigh) | Burning, sharp, tight | Walking, running, cycling |
What to Do When Your Leg Hurts
If you experience persistent leg pain when walking and bending, here are some general steps and considerations:
Initial Self-Care (RICE Protocol)
- Rest: Reduce activities that aggravate the pain.
- Ice: Apply ice to the painful area for 15-20 minutes several times a day.
- Compression: Use a compression bandage to help reduce swelling.
- Elevation: Elevate your leg to reduce swelling.
When to Seek Professional Help
It's important to consult a healthcare professional, such as a doctor or physical therapist, if:
- Your pain is severe or worsens significantly.
- You experience swelling, redness, or warmth around the knee.
- You cannot put weight on your leg.
- The pain doesn't improve with rest and self-care.
A professional can accurately diagnose the cause of your pain and recommend a personalized treatment plan, which may include physical therapy exercises, stretches, orthotics, or in some cases, other medical interventions.
Preventive Measures
- Warm-up and Cool-down: Always warm up before activity and cool down afterward with stretches.
- Proper Footwear: Wear supportive shoes appropriate for your activity.
- Gradual Increase in Activity: Avoid sudden increases in intensity or duration of exercise.
- Strength and Flexibility: Incorporate exercises to strengthen the muscles around your knee and hip (quadriceps, hamstrings, glutes) and improve flexibility.
