🩺Knee Pain When Walking, Squatting, or Climbing Stairs: What Could Be Contributing?

Knee pain can make everyday activities more difficult than they should be. Walking through the grocery store, getting up from a chair, squatting at the gym, or climbing a flight of stairs may become uncomfortable when the knee is irritated.

But knee pain does not always originate from the same problem. Symptoms may be associated with irritation around the kneecap, an overloaded tendon, osteoarthritis, a recent increase in physical activity, or movement patterns involving the hip, knee, and ankle.

Understanding what may be contributing to your symptoms is an important first step toward choosing an appropriate plan of care.

At Clearwater Sports & Wellness, P.A., Dr. Frank V. Sessa provides comprehensive musculoskeletal evaluations to help assess joint pain, movement limitations, and potential contributing factors. When appropriate, conservative chiropractic care, manual therapy, and individualized therapeutic exercises may be considered as part of a broader approach to improving mobility and function.

Why Does My Knee Hurt When I Walk, Squat, or Climb Stairs?

Different activities place different demands on the knee.

Walking repeatedly loads the knee as the body transfers weight from one leg to the other. Squatting requires coordinated movement of the hips, knees, and ankles. Climbing stairs increases the demands on the muscles that help control the knee and support the body’s weight.

Pain during these activities can have several possible explanations. The location of the pain, when it occurs, how long it has been present, and whether swelling or instability is present can all help guide an evaluation.

Common contributors include patellofemoral pain, tendon problems, osteoarthritis, training-related overload, and movement limitations elsewhere in the lower extremity.

1. Patellofemoral Pain: Pain Around or Behind the Kneecap

Patellofemoral pain involves the area where the kneecap, or patella, moves along the groove at the front of the thighbone.

People with this type of pain often describe an aching sensation around or behind the kneecap. Symptoms may become more noticeable when:

• Climbing or descending stairs
• Squatting or lunging
• Running or jumping
• Getting up after sitting for an extended period
• Performing repeated knee-bending activities

Patellofemoral pain can develop when the demands placed on this area exceed its current tolerance. Training changes, muscle capacity, movement coordination, and other individual factors may contribute.

It is not necessarily caused by a kneecap that is simply “out of place.” A proper assessment considers the overall presentation rather than assuming one specific structural problem.

Depending on the findings, management may involve modifying aggravating activities, gradually rebuilding strength and tolerance, and addressing relevant movement limitations.

2. Tendon Problems: When the Structures Connecting Muscle to Bone Become Irritated

Tendons connect muscles to bones and help transmit force during movement. Repeated or excessive loading can irritate a tendon and produce localized pain.

Two areas commonly associated with knee pain are the patellar tendon and the quadriceps tendon.

Patellar tendinopathy

The patellar tendon connects the bottom of the kneecap to the shinbone. Patellar tendinopathy, sometimes called jumper’s knee, is often associated with repeated jumping, running, and other activities that place substantial demands on the extensor mechanism of the knee.

Pain is commonly felt just below the kneecap and may worsen with jumping, squatting, or other forceful knee-extension activities.

Quadriceps tendinopathy

The quadriceps tendon connects the thigh muscles to the top of the kneecap. Irritation in this area can produce pain just above the kneecap, particularly during activities that require forceful contraction of the thigh muscles.

Tendon-related pain does not always improve with complete rest alone. Depending on the severity and diagnosis, a carefully progressed loading program may be helpful. However, sudden severe pain, a popping sensation, or an inability to straighten the knee or bear weight warrants prompt medical assessment because a significant tendon injury may be present.

3. Knee Osteoarthritis: When Joint Changes Affect Daily Activities

Osteoarthritis is a joint condition involving changes in cartilage and other joint tissues. In the knee, it may contribute to pain, stiffness, swelling, and reduced function.

Symptoms can include:

• Pain during walking or prolonged standing
• Stiffness after sitting or upon getting up in the morning
• Discomfort when climbing stairs or standing from a chair
• Swelling or reduced range of motion
• A grinding or creaking sensation during movement

Symptoms vary considerably. Some people have noticeable changes on X-rays with relatively little pain, while others experience substantial discomfort.

Age, previous knee injuries, body weight, genetics, and other factors may influence the likelihood of developing knee osteoarthritis. However, knee pain should not automatically be attributed to arthritis based on age alone.

Management often focuses on maintaining appropriate activity, improving strength and function, and adjusting activities to match current tolerance. A clinician may recommend medical evaluation, physical therapy, medication guidance from an appropriate healthcare professional, or imaging when indicated.

Chiropractic care may complement a broader conservative management plan when appropriate, but it does not reverse osteoarthritis or restore lost cartilage.

4. Training Loads: Have You Increased Activity Too Quickly?

Sometimes, knee pain develops after a change in routine rather than a single injury.

Examples include increasing running mileage, adding hill workouts, beginning a new strength-training program, increasing squat depth or resistance, or returning to exercise after time away.

The body needs time to adapt to changes in training demands. When the amount or intensity of activity exceeds the knee’s current capacity, symptoms may develop.

Pay attention to whether your pain began after:

• Increasing workout frequency or duration
• Adding more stairs, hills, or jumping exercises
• Lifting heavier weights
• Changing shoes, surfaces, or training methods
• Returning to sports after a break

The solution is not necessarily to stop exercising altogether. Depending on the cause and severity, temporarily reducing the most aggravating activities and gradually rebuilding tolerance may be more appropriate.

Persistent or worsening pain deserves an evaluation rather than repeated attempts to push through symptoms.

5. Hip and Ankle Mechanics: Could Other Joints Be Contributing?

The knee does not work independently. It functions as part of a coordinated lower-extremity system involving the hip, knee, ankle, and foot.

Movement limitations or reduced strength elsewhere may influence how forces are distributed during walking, squatting, running, and stair climbing.

Hip strength and movement control

The muscles around the hip help control the position of the thigh during weight-bearing activities. In some individuals, reduced strength or coordination may contribute to movement patterns that increase demands on the knee.

This does not mean weak hip muscles are always the cause of knee pain. Their relevance depends on the individual’s symptoms, examination findings, and activity demands.

Ankle mobility

The ankle needs sufficient mobility for many common movements, including squatting and descending stairs. Limited ankle dorsiflexion, which is the ability to bring the shin forward over the foot, may change how a person performs these movements.

The body may compensate by changing foot position, heel contact, trunk position, or knee movement. Whether these changes contribute to symptoms varies from person to person.

Foot mechanics and the entire movement pattern

Foot movement and lower-extremity alignment may also be relevant in selected cases. However, there is no single ideal movement pattern that applies to everyone, and visible differences do not automatically indicate a problem.

A comprehensive musculoskeletal evaluation can help determine whether hip strength, ankle mobility, foot mechanics, or another factor is relevant to the person’s knee symptoms.

How Can You Tell What Is Contributing to Your Knee Pain?

The location of the pain can offer clues, but it cannot establish a diagnosis on its own.

For example:

• Pain around or behind the kneecap may be consistent with patellofemoral pain.
• Pain just below the kneecap may be associated with patellar tendon problems.
• Pain above the kneecap may involve the quadriceps tendon.
• More generalized pain with stiffness may occur with osteoarthritis.
• Pain that begins after a training increase may reflect an overload problem or another injury.

These patterns can overlap. Meniscus injuries, ligament injuries, bursitis, referred pain, and other conditions may also cause knee symptoms.

An evaluation typically considers the history of the problem, the mechanism of injury if applicable, swelling, range of motion, strength, walking mechanics, and relevant hip and ankle function. Specific examination procedures are selected based on the presentation.

The goal is to identify the most likely contributors, recognize conditions that need medical attention, and determine whether conservative care is appropriate.

What May Help When Knee Pain Develops?

The appropriate approach depends on the underlying cause, symptom severity, and physical demands of the individual.

Modify aggravating activities

Temporarily reduce the depth, resistance, speed, or volume of movements that consistently aggravate your symptoms. This may mean modifying squats, reducing hill work, or limiting repeated stair climbing while the problem is assessed.

Avoid assuming that every painful movement is causing damage, but do not repeatedly force movements through significant or worsening pain.

Maintain appropriate movement

Complete inactivity is not always necessary. Gentle movement and tolerable activity may help maintain function, depending on the condition. Significant injuries or specific diagnoses may require different restrictions.

Progress strength and mobility appropriately

When indicated, an individualized exercise program may address quadriceps and hip strength, lower-extremity coordination, ankle mobility, or gradual tendon loading.

Exercises should match the person’s presentation and current capacity. A program that is appropriate for patellofemoral pain may not be suitable for an acute tendon tear or another significant injury.

Consider a comprehensive musculoskeletal evaluation

When knee pain persists, recurs, or interferes with normal activities, an evaluation can help clarify the possible sources of symptoms and identify appropriate next steps.

At Clearwater Sports & Wellness, P.A., Dr. Sessa can assess relevant musculoskeletal factors and determine whether conservative chiropractic care, manual therapy, or individualized therapeutic exercises may be appropriate. When findings suggest a condition outside the scope of chiropractic care, medical referral is an important part of responsible management.

When Should Knee Pain Be Medically Evaluated or Imaged?

Not all knee pain requires imaging. Many conditions can initially be assessed through a medical history and physical examination. Imaging decisions depend on the suspected diagnosis, injury mechanism, examination findings, and how symptoms progress.

Seek urgent medical assessment when:

• The knee becomes severely swollen soon after an injury.
• You cannot bear weight or move the knee normally after an injury.
• The knee appears deformed or feels unstable following significant trauma.
• The knee is hot, red, and swollen, particularly with fever or feeling generally unwell.
• You develop severe pain or other rapidly worsening symptoms.

A sudden inability to straighten the knee, especially after an injury, also warrants prompt assessment.

When might imaging be appropriate?

X-rays may be considered when a fracture or osteoarthritis is suspected, depending on the injury and examination findings.

MRI may be appropriate when a significant ligament, meniscus, tendon, cartilage, or other internal knee injury is suspected, particularly if the result would change treatment or further evaluation is needed.

Ultrasound can help assess selected tendon and soft-tissue problems in appropriate circumstances.

Imaging is not automatically necessary for every episode of knee pain. A healthcare professional can determine whether it is likely to provide useful information. Referral to a physician or orthopedic specialist may be appropriate when symptoms are severe, persistent, unexplained, or suggest an injury requiring additional management.

A Practical Approach to Knee Pain

Knee pain during walking, squatting, or climbing stairs can have several contributing factors. Patellofemoral pain, tendon problems, osteoarthritis, changes in training loads, and hip or ankle mechanics are among the possibilities.

The most useful next step is to understand the individual’s symptoms and examination findings rather than assume that every case has the same cause.

If knee pain is limiting your workouts, walking, or everyday activities, a comprehensive musculoskeletal evaluation may help identify relevant contributing factors and guide appropriate care.
