Why does a simple bend of the knee cause so much discomfort?
You’re getting up from a chair, climbing stairs, or maybe just squatting to pick something up and suddenly, my knee hurts when I bend it and straighten it. If that sounds like you, you’re not alone. Many people report knee pain while bending, especially with a pain on the outside of the knee or a feeling that their knee feels tight when bending. But what does this pain really mean?
Let’s dive into the possible reasons from a physiotherapist’s lens and look at how you can recover and prevent future pain.
What’s Really Happening Inside Your Knee?
The knee is a complex hinge joint it’s not just a back-and-forth movement. It involves rolling, sliding, and rotating motions. When you bend or straighten your knee, these motions need to happen smoothly. If there’s tightness, inflammation, or an imbalance in muscle control, pain is often the result.
A common complaint we hear is: my knee hurts when I bend it and straighten it. The pain may be dull, sharp, or aching. It can stem from the joint, the surrounding muscles, the patella (kneecap), or the tendons and ligaments around it.
What Are the Common Causes of Knee Pain While Bending?
- Patellofemoral Pain Syndrome (Runner’s Knee): Often triggered by poor biomechanics or muscle imbalances, this is a top reason people report that my knee hurts when I bend it and straighten it. It causes discomfort around or behind the kneecap, worsens while climbing stairs, and often feels like a dull ache during sitting.
- Iliotibial Band Syndrome (ITBS): This is a leading cause of lateral knee pain. The IT band runs from your hip to your knee and when it’s tight, it rubs against the thigh bone during bending. That friction creates a distinct pain on the outside of the knee, particularly noticeable during squats or prolonged walking or running.
- Meniscus Injuries: Menisci are the shock absorbers of the knee. A small tear often from a twist or trauma can cause a catching or locking sensation, swelling, and that familiar line: my knee hurts when I bend it and straighten it.
- Tendonitis: Overuse or improper loading may inflame the tendons, causing knee pain while bending. In some cases, the knee feels tight when bending, especially in the front or on the lateral side of the knee.
Why Does the Pain Feel Worse on the Outside?
If you’re feeling a pain on the outside of your knee (or lateral knee pain), your body might be telling you about:
- Tight IT Band: As mentioned, it’s often responsible for pain on the lateral side of the knee
- LCL Sprain: The Lateral Collateral Ligament can get overstretched or sprained during sudden directional changes.
- Improper Movement Patterns: Poor posture, weak glutes, or flat feet can shift pressure unevenly to the lateral side of the knee.
This type of pain often presents subtly at first, only during exercise or deep bending. Over time, it progresses turning into a constant throb with every movement.
Why Does My Knee Feel Tight When I Bend It?
A knee that feels tight when bending can mean a few things:
- Swelling in the Joint: Fluid build-up creates pressure.
- Scar Tissue Formation: Post-surgery or old injuries can leave behind tight fibrous tissues.
- Muscle Imbalance: Tight quads or hamstrings can limit knee mobility.
This tightness not only contributes to discomfort but also reduces overall knee flexibility, making the joint feel stiff and weak.
How a Physiotherapist Looks at Knee Pain
When a patient says, my knee hurts when I bend it and straighten it, a good physiotherapist won’t just treat the pain we investigate the root. At BSI Physiotherapy, we start with:

Can You Prevent This Type of Knee Pain?
Absolutely. Once you know the triggers, you can prevent recurrence. Here are some physiotherapist-approved tips:
- Warm Up & Cool Down Properly: Neglecting this step often leads to injuries. Pre-exercise warm-ups prepare the muscles and joints for action, especially the knees.
- Strengthen the Right Muscles: Focus on your quadriceps, hamstrings, and glutes. Weak hips are directly linked to knee pain while bending.
- Work on Flexibility: Tight hamstrings and calves can increase stress on your knees, making your knee feel tight when bending.
- Correct Your Form: Whether it’s walking, squatting, or lifting improper technique will only worsen your symptoms.
When Should You See a Physiotherapist?
If you’ve been saying my knee hurts when I bend it and straighten it for more than a week it’s time. Ignoring it won’t help. If the pain worsens with activity, shows swelling, or makes it hard to bear weight, visit a specialist.
