Does your knee hurt when you climb stairs but feel fine walking on flat ground? You might feel pain around your kneecap, a sharp sensation when you step up, or stiffness when you come downstairs.
Climbing stairs puts more pressure on your knees than normal walking because your knees bend further and your leg muscles work harder. Common causes of knee pain when climbing stairs include patellofemoral pain, osteoarthritis, tendon problems, and meniscus injuries.
Knowing what might be causing the pain can help you understand which exercises may help and when it’s time to get your knee checked.
Why Does My Knee Hurt When Climbing Stairs but Not Walking?
When you climb stairs, your knees bend more than they do during normal walking. Your thigh and hip muscles also work harder to lift your body onto each step. This increases pressure around the knee, especially behind the kneecap.
That’s why you might walk comfortably on flat ground but feel pain when climbing stairs, squatting, or standing up from a chair.
Why Does Knee Pain Sometimes Feel Worse Going Downstairs?
When you walk downstairs, your thigh muscles control your body as you lower yourself onto the next step. This puts extra strain on the knee and may cause pain, particularly around the kneecap.
Pain on stairs doesn’t always mean you have a serious knee injury. If the pain keeps coming back, talk to a physiotherapist.
What Causes Knee Pain When Climbing Stairs?
Knee pain on stairs can happen for several reasons. Where the pain occurs, when it starts, and whether you have swelling or stiffness can help narrow down the possible causes.
1. Patellofemoral Pain
Patellofemoral pain, sometimes called runner’s knee, causes pain around or behind the kneecap. It often gets worse when climbing stairs, squatting, running, or sitting with bent knees for a long time. Suddenly increasing your activity or having weak thigh and hip muscles may contribute to the pain.
2. Knee Osteoarthritis
Knee osteoarthritis causes changes in the cartilage, bones, and other tissues within the joint. It can lead to pain, stiffness, swelling, and difficulty bending the knee. People with knee osteoarthritis may notice more pain when climbing stairs because the movement puts greater pressure on the joint.
3. Patellar Tendon Problems
The patellar tendon connects your kneecap to your shinbone. Repeated jumping, running, or suddenly increasing your exercise intensity can overload this tendon. Pain usually occurs just below the kneecap and may get worse when climbing stairs, squatting, or jumping.
4. Meniscus Injuries
The menisci are two pieces of cartilage that help cushion your knee and spread pressure across the joint. A meniscus injury may cause pain along the inner or outer side of the knee, swelling, catching, or difficulty bending it.
Not all knee pain starts with an injury. Pain can also develop gradually, especially after changes in exercise or daily activity. The location of your pain may offer clues, but it cannot confirm the cause on its own.
What Exercises Can Help Knee Pain When Climbing Stairs?
The exercises that help will depend on what’s causing your knee pain. For many people, strengthening the thigh and hip muscles can make climbing stairs and other everyday movements easier.
These four exercises may help, but not all of them will be suitable for every knee problem.
1. Quadriceps Sets
- Sit or lie down with your leg straight.
- Tighten your thigh muscles and gently press the back of your knee downward.
- Hold for a few seconds, then relax.
This exercise helps activate your thigh muscles without bending your knee much.
2. Straight-Leg Raises
- Lie on your back with one knee bent and the other leg straight.
- Tighten the thigh muscles of your straight leg.
- Slowly lift the straight leg, then lower it back down.
This strengthens your quadriceps without putting much pressure on a deeply bent knee.
3. Side-Lying Hip Raises
- Lie on your side with the leg you want to exercise on top.
- Keep your upper leg straight and slowly lift it.
- Lower it gently without rolling your hips backwards.
This exercise strengthens the muscles around your hips that help control leg movement.
4. Supported Sit-to-Stands
- Sit on a stable chair with your feet flat on the floor.
- Lean forward slightly and slowly stand up.
- Lower yourself back onto the chair with control.
Use your hands for support if needed. Starting with a higher chair may make the exercise easier.
What If Knee Exercises Make the Pain Worse?
Some mild discomfort can occur during exercise. However, sharp pain, increasing swelling, or pain that stays worse afterwards means the exercise may be too difficult.
Try reducing the movement or the number of repetitions. If the pain continues, stop that exercise and talk to a physiotherapist.
How often you exercise depends on what’s causing your pain and how your knee feels afterwards.
How Can You Relieve Knee Pain When Climbing Stairs at Home?
If your knee pain is mild and you haven’t had a significant injury, these changes may help:
- Reduce activities that increase pain: Cut back temporarily on repeated stair climbing, deep squats, or other painful movements.
- Use the handrail: Holding the railing can take some pressure off your knee.
- Take one step at a time: When going upstairs, step first with your stronger leg. When coming downstairs, lead with your painful leg. Use the handrail for support. This may make stairs easier while your knee is recovering.
- Use a cold pack: Apply a cold pack wrapped in a towel for 10–15 minutes to help with pain or swelling.
- Keep moving: Gentle walking or suitable low-impact exercises can help prevent stiffness.
You don’t need to stop all activity because of mild knee pain. Try to stay active without making your symptoms worse.
Why Is My Knee Pain Not Getting Better?
Knee pain may continue if the cause hasn’t been identified, your exercises are too difficult, or you’ve increased your activity too quickly.
Your knee might feel better after resting, but the pain can return when climbing stairs if your muscles are still weak or your knee isn’t ready for that level of activity.
Recovery time depends on the cause of the pain and how your knee responds to treatment. As your pain improves and your knee becomes stronger, you can gradually return to climbing stairs normally, provided your symptoms don’t get worse.
When Should You See a Physiotherapist for Knee Pain?
If knee pain keeps coming back, isn’t improving, or starts affecting your daily activities, it’s a good time to have it checked.
A physiotherapist can assess your knee movement, muscle strength, balance, and the movements that cause pain. This can help identify what needs to change in your exercises or daily activities.
Get urgent medical attention if you cannot put weight on your leg, have severe swelling after an injury, notice a change in your knee’s shape, or have a hot, red knee with fever.

Frequently Asked Questions
Can Knee Pain When Climbing Stairs Occur Without Swelling?
Yes. Conditions such as patellofemoral pain can cause knee pain without noticeable swelling. However, the absence of swelling doesn’t rule out other knee problems.
Is It Okay to Climb Stairs When You Have Knee Pain?
It depends on what’s causing the pain. Mild discomfort may be manageable by using a handrail or taking one step at a time. If climbing stairs causes sharp pain, worsening symptoms, or knee instability, get your knee checked before continuing.
How Long Does Knee Pain When Climbing Stairs Take to Improve?
Recovery time depends on what’s causing the pain and how your knee responds to treatment. Some people improve with changes to their activities and suitable exercises, while others need more time and a structured rehabilitation plan.
Can Knee Pain When Climbing Stairs Go Away With Exercise?
Exercise can help with many causes of knee pain, especially when weak muscles or difficulty handling activity contribute to the symptoms. However, the right exercises depend on the cause of your pain. If symptoms continue or get worse, have your knee assessed.
