Quick Answer
Knee pain going up and down stairs can happen when the kneecap, tendons, joint, or surrounding muscles are struggling with the amount of load being placed on the knee. Patellofemoral pain, knee arthritis, patellar tendon irritation, meniscus problems, and sudden changes in activity are some possible causes.
Pain around or behind the kneecap that becomes worse with stairs, squatting, running, or sitting with the knee bent for a long time is especially common with patellofemoral pain, sometimes called runner’s knee. The American Academy of Orthopedic Surgeons lists stairs, running, jumping, and squatting among activities that commonly aggravate patellofemoral pain.
The location of your pain, whether there is swelling, how strong the knee feels, and whether it catches, locks, or gives way can all help determine what may be contributing.
What Knee Pain Going Up and Down Stairs Can Feel Like
Knee pain going up and down stairs may feel like:
- Aching around or behind the kneecap
- Sharp pain during a step
- Pain underneath the kneecap
- Stiffness after sitting
- Grinding or clicking
- Tenderness below the kneecap
- Pain along the inside of the knee
- Weakness while pushing yourself up a step
- Discomfort when squatting
- Swelling after activity
For some people, knee pain going up and down stairs is one of the first signs that the knee is having difficulty tolerating its current activity or training demands.
5 Common Causes of Knee Pain Going Up and Down Stairs
1. Patellofemoral Pain
Patellofemoral pain is a common reason for pain around the front of the knee during stairs.
The patella, or kneecap, moves as the knee bends and straightens. Activities such as stairs, squats, running, and jumping repeatedly load the area around the kneecap.
You may notice:
- Pain around or behind the kneecap
- Pain going downstairs
- Pain climbing upstairs
- Pain with squats or lunges
- Aching after sitting with the knee bent
- Clicking or crackling
- Symptoms after increasing workouts or running
Knee pain going up and down stairs is especially common with patellofemoral pain because stair climbing repeatedly places demand on the area around the kneecap.
You can read more about this condition from the American Academy of Orthopaedic Surgeons.
You can also read our guide to runner’s knee treatment in Woodbridge for more information about kneecap-related pain.
2. Knee Osteoarthritis
Knee osteoarthritis can cause pain, stiffness, swelling, and difficulty with everyday movements.
Symptoms may include:
- Stiffness after sitting or resting
- Pain with walking
- Difficulty climbing stairs
- Grinding or clicking
- Reduced knee movement
- Swelling
- A feeling of weakness or instability
When arthritis affects the area around the kneecap, stairs and squatting may become particularly uncomfortable. AAOS notes that patellofemoral arthritis can make climbing and descending stairs difficult.
With arthritis, knee pain going up and down stairs may occur alongside stiffness, swelling, reduced movement, or aching after periods of rest.
Having pain on stairs does not automatically mean you have arthritis. Your symptoms, age, health history, movement, strength, and sometimes imaging all need to be considered.

3. Patellar Tendon Irritation
The patellar tendon connects the kneecap to the shinbone and plays an important role when the knee straightens.
Patellar tendinopathy, sometimes called jumper’s knee, commonly causes pain between the kneecap and the shinbone.
You may notice:
- Pain directly below the kneecap
- Tenderness over the tendon
- Pain during jumping
- Pain during running
- Symptoms after a hard leg workout
- Pain when rising from a chair
- Pain while climbing stairs
Mayo Clinic notes that patellar tendon pain can eventually affect everyday movements such as climbing stairs or rising from a chair.
When this tendon becomes irritated, knee pain going up and down stairs may be felt more directly underneath the kneecap.
Read more about patellar tendinitis from Mayo Clinic.
4. Meniscus or Other Knee Injury
If your pain began after twisting, pivoting, falling, playing sports, or another injury, a structure inside the knee may have been injured.
A meniscus injury can cause:
- Pain
- Swelling
- Stiffness
- Catching
- Locking
- A sensation that the knee gives way
- Difficulty fully bending or straightening the knee
AAOS lists pain, stiffness, swelling, catching or locking, giving way, and reduced range of motion among common symptoms of a meniscus tear.
Because stairs require repeated bending while supporting your body weight, knee pain going up and down stairs may become more noticeable after a knee injury.
Pain after an injury combined with significant swelling, locking, or instability should be assessed.
5. A Sudden Increase in Activity or Reduced Strength
Sometimes knee pain going up and down stairs starts without one obvious injury.
Think about what changed recently.
Did you:
- Return to the gym?
- Add squats or lunges?
- Increase your running distance?
- Start playing a new sport?
- Walk significantly more while travelling?
- Add hill training?
- Start taking more stairs?
- Return to exercise after months off?
Changes in training load and activity level can contribute to patellofemoral pain.
If knee pain going up and down stairs started shortly after increasing your workouts, running, walking, or sports, your knee may need time and gradual strengthening to adapt.
A physiotherapy assessment in Vaughan can assess strength, mobility, functional movement, activity tolerance, and other factors that may be contributing.
5 Effective Tips for Knee Pain Going Up and Down Stairs
The best approach to knee pain going up and down stairs depends on what is causing it. In many cases, managing aggravating activity and gradually rebuilding strength and movement tolerance can be important parts of rehabilitation.
1. Reduce What Keeps Irritating the Knee
You may not need to stop everything.
Instead, temporarily reduce activities that repeatedly cause a large flare-up, such as:
- Multiple flights of stairs
- Deep squats
- Heavy lunges
- Hill running
- Jumping
- High-volume leg workouts
Mayo Clinic recommends reducing activities that aggravate patellofemoral pain, including stairs, kneeling, and squatting, while symptoms are irritated.
The goal is usually to gradually return to these movements rather than avoid them forever.
2. Build Quadriceps Strength
Your quadriceps help control and straighten the knee.
Depending on your symptoms, rehabilitation may eventually include:
- Sit-to-stands
- Step-ups
- Controlled step-downs
- Knee-extension exercises
- Squat variations
Improving quadriceps strength can help prepare the knee for activities that trigger knee pain going up and down stairs.
The correct starting level matters. If stairs already cause significant pain, immediately doing large volumes of painful step-downs may not be appropriate.
3. Strengthen Your Hips
Knee rehabilitation does not always stop at the knee.
Your hip muscles help control the thigh and pelvis during walking, stairs, running, squatting, and single-leg activities.
Exercises may include:
- Glute strengthening
- Hip abductor strengthening
- Balance exercises
- Single-leg control work
- Progressive lower-body strengthening
When knee pain going up and down stairs keeps returning, looking at the hip, knee, ankle, and overall movement pattern can provide more information than focusing only on the painful spot.
4. Gradually Rebuild Stair Tolerance
Avoiding stairs forever is usually not the goal.
As symptoms become more manageable and strength improves, stair-related movements can gradually be added back.
A progression may include:
- Sit-to-stands
- Small step-ups
- Regular step-ups
- Controlled step-downs
- Normal stair climbing
The appropriate progression depends on your symptoms and assessment.
Knee pain going up and down stairs should gradually become easier to manage as your knee becomes stronger and more tolerant of the movement.
5. Look at the Whole Problem
A knee assessment may look at more than just the painful area.
This can include:
- Knee movement
- Quadriceps strength
- Hip strength
- Balance
- Squatting mechanics
- Walking
- Running
- Ankle mobility
- Training volume
- Previous injuries
If knee pain going up and down stairs continues despite changing your activity, addressing contributing strength and movement factors may be useful.
Do This, Avoid This
Do This
- Keep moving within a comfortable range
- Temporarily modify activities that cause significant flare-ups
- Build knee strength gradually
- Include hip strengthening when appropriate
- Increase training volume gradually
- Monitor swelling and instability
- Get recurring symptoms assessed
Avoid This
- Pushing through sharp pain on every flight of stairs
- Suddenly doubling your running or leg-training volume
- Repeatedly testing painful deep squats
- Assuming all clicking means damage
- Completely avoiding knee movement for weeks
- Assuming every knee problem is runner’s knee
- Ignoring locking, major swelling, or instability
What About Clicking or Grinding?
Clicking, popping, or grinding by itself does not automatically tell you what is wrong with the knee.
These noises may occur with several different knee conditions. What matters more is whether the noise occurs along with:
- Pain
- Swelling
- Locking
- Instability
- Loss of movement
- A recent injury
Knee symptoms can include popping or crunching as well as stiffness, swelling, instability, and difficulty fully straightening the knee.
Can Massage Help Knee Pain?
Massage therapy in Woodbridge may be helpful when tight or overworked muscles around the quadriceps, hamstrings, calves, or hips are contributing to discomfort.
Massage does not address every cause of knee pain. Meniscus injuries, significant arthritis, tendon problems, and other conditions may require a broader treatment plan.
When to Book a Knee Assessment
Recurring knee pain going up and down stairs should be assessed when it starts limiting work, exercise, sports, or normal daily activities.
Consider booking when:
- You are avoiding stairs because of pain
- The knee feels weaker
- Pain affects workouts or sports
- You have recurring swelling
- The knee feels unstable
- You cannot squat comfortably
- Pain persists after reducing aggravating activities
- Knee movement is becoming limited
- You are unsure what is causing the pain
At Physiotemple Health, an assessment may include knee mobility, strength, hip control, balance, functional movements, activity history, and other relevant factors.
Depending on your assessment, your care may include physiotherapy, chiropractic care, massage therapy, acupuncture, exercise rehabilitation, or activity guidance. Physiotemple currently lists Physiotherapy, Chiropractic, Massage Therapy, Acupuncture and other services at its Woodbridge location.
When Knee Pain Needs Urgent Medical Attention
Seek prompt medical attention after a significant injury if:
- You cannot put weight on the knee
- The knee looks deformed
- You have intense pain
- The knee suddenly becomes significantly swollen
- You heard a major pop during the injury and lost function
Mayo Clinic advises urgent medical attention after a major knee injury when the knee is deformed, cannot bear weight, causes intense pain, or swells suddenly.
A hot, red, swollen knee with fever or feeling seriously unwell should also be medically assessed promptly.
FAQs About Knee Pain Going Up and Down Stairs
Why does my knee hurt when going downstairs?
Going downstairs repeatedly loads the knee while your leg controls your body as you lower onto the next step. Patellofemoral pain commonly becomes worse during activities that repeatedly bend the knee, including stairs.
Is knee pain on stairs runner’s knee?
It can be, but not always. Patellofemoral pain is one common cause, but arthritis, tendon irritation, meniscus injuries, and other knee problems can produce similar symptoms.
Why does my knee hurt after sitting and then using stairs?
Pain after keeping the knee bent for a long time is commonly reported with patellofemoral pain.
Should I stop using stairs?
Not necessarily. You may temporarily reduce unnecessary stair use when it causes a significant flare-up, but the longer-term goal is usually to improve strength and gradually restore tolerance when appropriate.
Can physiotherapy help knee pain on stairs?
Physiotherapy can assess strength, mobility, functional movement, activity tolerance, and other factors contributing to symptoms. Physiotemple offers physiotherapy in Vaughan and Woodbridge.
Do I need an MRI?
Not everyone with knee pain requires an MRI. Whether imaging is appropriate depends on the injury history, examination findings, symptoms, and clinical concerns.
