Understanding Knee Pain: Causes, Symptoms, and When to Seek Care

Knee pain is one of the most common reasons people seek orthopaedic care. Whether it develops suddenly after an injury or gradually over time, knee pain can affect your ability to walk, exercise, work, or enjoy everyday activities. The knee is one of the body’s largest and hardest working joints, making it especially vulnerable to strain, wear and tear, and injury.

At Orthopaedic Associates, we help patients identify the source of their knee pain and create personalized treatment plans to help them get back to moving comfortably.

Common Causes of Knee Pain

Knee pain can happen for many reasons, and the cause often depends on factors such as age, activity level, lifestyle, and overall health.

Some of the most common causes include:

Osteoarthritis

Often referred to as "wear and tear" arthritis, osteoarthritis occurs when the cartilage cushioning the knee joint gradually breaks down. This can lead to pain, stiffness, swelling, and decreased mobility over time.

Tendonitis

Overuse or repetitive movement can irritate the tendons around the knee. Conditions like patellar tendonitis, sometimes called "jumper’s knee," commonly affect athletes and active individuals.

Ligament Injuries

The knee relies on several important ligaments for stability. Injuries to the ACL, MCL, PCL, or LCL can happen during sports, falls, or sudden twisting movements.

Meniscus Tears

The meniscus acts as a cushion between the thighbone and shinbone. Twisting or pivoting motions can cause tears, especially during athletic activities or sudden movements.

Bursitis

Small fluid filled sacs called bursae help reduce friction around the knee joint. Repetitive kneeling or overuse can cause these sacs to become inflamed.

Fractures

Falls, direct impact injuries, or accidents can cause fractures involving the kneecap or bones surrounding the knee.

Overuse and Muscle Imbalances

Sometimes knee pain does not begin in the knee itself. Weakness or tightness in the hips, legs, or core can alter movement patterns and place extra stress on the joint.

Symptoms That Should Not Be Ignored

Knee pain can range from mild discomfort to severe pain that limits daily activity. Symptoms vary depending on the underlying cause.

Common symptoms include:

• Pain during activity or movement
• Swelling around the joint
• Stiffness or decreased range of motion
• Popping, clicking, or grinding sensations
• Instability or feeling like the knee may "give out"
• Difficulty walking or bearing weight
• Locking of the knee joint
• Warmth or redness around the knee

Some symptoms may develop gradually, while others appear immediately after an injury.

When Should You Seek Care?

Occasional soreness after exercise or increased activity is normal. However, persistent or worsening symptoms may indicate a more serious issue.

Consider seeking evaluation if:

• Pain lasts more than a few days and does not improve with rest
• Swelling continues or worsens
• You cannot fully bend or straighten the knee
• Walking becomes difficult
• The knee feels unstable or repeatedly gives out
• You heard a pop during an injury
• Pain interferes with work, sleep, exercise, or daily activities
• You cannot bear weight on the affected leg

Early evaluation can help identify problems before they become more severe and may lead to better treatment outcomes.

Treatment Options for Knee Pain

Treatment depends on the cause and severity of symptoms. Many cases improve with conservative treatments such as:

• Activity modification
• Rest and ice
• Physical therapy
• Bracing
• Anti-inflammatory medications
• Injections

For more advanced conditions or injuries, additional treatment options, including surgical care, may be recommended.
