7 Common Causes of Knee Pain

Knee pain can make everyday activities such as walking, climbing stairs, getting up from a chair, or standing for long periods uncomfortable. For adults over 40, recurring knee discomfort may gradually affect mobility, sleep, and independence. However, knee pain is not always caused by ageing, and different conditions can produce similar symptoms.

Understanding the causes of knee pain in Nashik and knowing when to seek medical advice can help you take the next appropriate step. Common causes include osteoarthritis, ligament injuries, meniscus tears, tendon irritation, bursitis, overuse, and other joint conditions.

At Reliable Super Speciality Hospital, Satpur–Ambad Link Road, Nashik, patients can seek appropriate medical evaluation for knee pain and related injuries.

What Are the Common Causes of Knee Pain?

The seven common causes of knee pain are:

1. Osteoarthritis: Gradual changes in the cartilage and other structures within the knee joint.
2. Ligament injuries: Damage to the tissues that stabilise the knee.
3. Meniscus tears: Injury to the cartilage that cushions the knee joint.
4. Tendinitis or tendinopathy: Irritation or changes in a tendon around the knee.
5. Bursitis: Inflammation of a small fluid-filled cushioning sac near the joint.
6. Overuse and muscle strain: Pain associated with repetitive activity or increased physical demands.
7. Other joint conditions, including inflammatory arthritis or gout: Conditions that may cause pain, swelling, warmth, and stiffness.

These conditions can have overlapping symptoms. The location of pain or the presence of swelling alone cannot confirm a diagnosis. A healthcare professional can assess your symptoms and recommend further evaluation if necessary.

1. Osteoarthritis of the Knee

Osteoarthritis is a common cause of persistent knee pain in middle-aged and older adults. It involves changes in the cartilage, bone, and other tissues of the joint over time.

As the condition develops, a person may experience:

• Pain during walking or prolonged standing.
• Stiffness after resting or waking up.
• Discomfort while climbing or descending stairs.
• Swelling or reduced flexibility.
• Difficulty completing routine daily activities.

Symptoms may develop gradually and can vary from day to day. Previous knee injuries, age-related changes, joint structure, and other individual factors may contribute to the condition.

What can help?

Treatment depends on the severity of symptoms and their effect on daily life. A doctor may recommend suitable physical activity, physiotherapy, strengthening exercises, weight management when appropriate, medication, or other treatment options. Some people with advanced disease may be considered for surgery, but surgery is not necessary for everyone.

If knee stiffness or pain repeatedly interferes with your routine, an orthopedic evaluation can help clarify the cause and available management options.

2. Knee Ligament Injuries

Ligaments are strong bands of tissue that help stabilise the knee. A sudden twist, fall, collision, or change in direction can stretch or tear a ligament.

Ligament injuries may cause:

• Sudden pain after an injury.
• Swelling around the knee.
• A popping sensation or sound at the time of injury.
• A feeling that the knee is unstable or may give way.
• Difficulty walking or bearing weight.

These symptoms do not automatically mean a ligament is torn. Other injuries can produce similar signs, so clinical assessment is important.

What should you do?

Stop the activity that caused the pain and avoid forcing the knee to move. Seek prompt medical evaluation if the pain is severe, the knee swells rapidly, or walking becomes difficult. A significant injury may require imaging and specialist assessment.

Treatment can range from activity modification and rehabilitation to surgical management in selected cases, depending on the injury and the person's needs.

3. Meniscus Tears

The menisci are two pieces of cartilage inside the knee that help distribute load and cushion movement between the thighbone and shinbone. A meniscus can tear after a twisting injury, particularly when the foot remains planted while the knee turns. Tears can also occur with age-related changes in the tissue.

Possible symptoms include:

• Pain along the inner or outer side of the knee.
• Swelling or stiffness.
• Difficulty bending or straightening the leg fully.
• Catching, locking, or a sensation that movement is restricted.
• Discomfort when turning or squatting.

Some meniscus tears cause mild symptoms, while others significantly limit movement. Symptoms alone cannot establish whether a tear is present.

How is it managed?

A clinician may assess knee movement, stability, tenderness, and the history of the injury. Imaging may be recommended when appropriate. Depending on the tear, treatment may include activity modification, physiotherapy, pain management, or surgery in selected cases.

A knee that becomes locked or cannot be straightened after an injury needs prompt medical assessment.

4. Tendinitis and Tendon Irritation

Tendons connect muscles to bones and help produce movement. Repetitive loading, sudden increases in activity, or certain physical demands can irritate the tendons around the knee.

Pain may occur near the kneecap or below it and can become more noticeable during climbing stairs, squatting, running, jumping, or repeatedly standing up.

Possible contributing factors include:

• Increasing exercise intensity too quickly.
• Repeated movements that place stress on the knee.
• Inadequate recovery between demanding activities.
• Changes in muscle strength or movement patterns.

What can help?

Reducing or temporarily modifying activities that aggravate the pain may help. Depending on the assessment, a healthcare professional may recommend a gradual return to activity and targeted strengthening exercises. Persistent or worsening symptoms should not be ignored, especially if they limit normal movement.

5. Knee Bursitis

Bursae are small, fluid-filled sacs that reduce friction between tissues around a joint. When a bursa becomes irritated or inflamed, it can cause local pain and swelling.

Knee bursitis may develop after repeated kneeling, prolonged pressure on the knee, an injury, or certain medical conditions.

Symptoms can include:

• Localised swelling.
• Tenderness around the affected area.
• Pain when kneeling or bending the knee.
• Warmth around the swollen area.

The exact symptoms depend on which bursa is affected. Infection can also cause inflammation in a bursa, so a hot, red, painful swelling—particularly with fever—needs urgent medical assessment.

Treatment depends on the cause and may include avoiding pressure, modifying activities, and clinician-recommended treatment. Do not attempt to drain a swollen area yourself.

6. Overuse and Muscle Strain

Not every episode of knee pain is caused by arthritis or a major injury. Repeated movements, a sudden increase in walking or exercise, prolonged standing, or an awkward movement can strain muscles and other soft tissues around the knee.

This type of discomfort may be more noticeable after activity and may improve with appropriate rest and modification of the movements that trigger it.

People whose work involves prolonged standing, frequent stair climbing, repeated squatting, or physically demanding tasks may need to pay attention to how their knees respond to these activities.

What can you do?

• Temporarily reduce activities that increase the pain.
• Avoid pushing through significant discomfort.
• Use a wrapped ice pack for short periods if it helps with pain or swelling.
• Return to activity gradually as symptoms improve.
• Seek medical advice if the pain persists, returns frequently, or affects daily activities.

Prolonged inactivity is not always helpful. The appropriate level of movement depends on the symptoms and whether an injury has occurred.

7. Other Joint Conditions, Including Inflammatory Arthritis and Gout

Knee pain can also result from conditions that cause inflammation inside or around the joint.

Inflammatory arthritis may cause joint pain, swelling, and stiffness. Depending on the condition, symptoms may affect more than one joint and may be particularly noticeable after periods of rest.

Gout occurs when urate crystals accumulate in a joint, leading to sudden episodes of intense pain and inflammation. Although gout often affects the big toe, it can also affect the knee.

Other less common but important causes include joint infection. A knee that suddenly becomes very painful, hot, red, or swollen—especially when accompanied by fever or feeling unwell—needs urgent medical assessment.

Do not assume that a swollen knee is simply arthritis or gout. A clinician may need to examine the joint and arrange tests to identify the cause and determine the appropriate treatment.

Why Does Knee Pain Become More Noticeable After Age 40?

Age can be one factor in knee problems, but it is not the only explanation. Over time, changes in joint tissues, previous injuries, muscle strength, activity patterns, and other health conditions may affect how the knee functions.

Knee pain may also become more noticeable when someone increases physical activity suddenly or spends long periods in positions that place stress on the joint.

For adults over 40, persistent pain should not automatically be dismissed as a normal part of ageing. Identifying the underlying cause can help guide appropriate treatment and activity choices.

When Should You Consult an Orthopedic Doctor?

Consider arranging a medical assessment if:

• Knee pain keeps returning or does not improve.
• Pain interferes with walking, stairs, sleep, or daily activities.
• Swelling or stiffness persists.
• The knee feels unstable or repeatedly gives way.
• You have difficulty bending or straightening the knee.
• You develop symptoms after a fall, twist, or other injury.

Seek urgent medical care if you cannot bear weight, have severe pain after an injury, develop major or rapid swelling, notice an obvious deformity, or cannot move the knee normally after an injury. A hot, red, swollen knee accompanied by fever or feeling unwell also requires urgent assessment.

Do not wait for a routine appointment if serious warning signs are present.

How Is the Cause of Knee Pain Identified?

A clinician generally starts by asking when the pain began, where it occurs, whether an injury preceded it, and which activities make it better or worse.

The assessment may include:

• Medical history: Previous injuries, existing health conditions, and the pattern of symptoms.
• Physical examination: Assessment of swelling, tenderness, movement, and joint stability.
• Imaging: An X-ray or other imaging may be recommended depending on the suspected cause.
• Additional tests: Blood tests or joint-fluid analysis may be needed when an inflammatory condition, gout, or infection is suspected.

Not everyone needs every test. The appropriate investigation depends on the clinical findings.

What Can You Do to Manage Knee Pain Safely?

If the pain is mild, there is no serious injury, and you can still move around safely, the following measures may help while you monitor your symptoms:

1. Modify painful activities. Temporarily reduce movements that aggravate the knee.
2. Apply a wrapped ice pack. Use it for up to 20 minutes at a time; do not apply ice directly to the skin.
3. Maintain appropriate movement. Avoid forcing painful movements, but do not assume complete inactivity is always best.
4. Choose suitable exercise. A healthcare professional or physiotherapist can help identify activities and strengthening exercises that suit your condition.
5. Seek advice before using medication. Pain medicines may not be suitable for everyone, particularly people with certain medical conditions or those taking other medicines.
6. Arrange an assessment when needed. Persistent, worsening, or recurring pain deserves medical attention.

These steps may help with symptoms, but they do not replace assessment when a significant injury or another serious condition is possible.
