What Causes Knee Pain?

Knee pain can develop for many reasons, from everyday wear and tear to injuries and certain medical conditions. Identifying the source of your pain is an important first step in finding the right treatment and relief.

Wear and Tear on the Joint

As we age, the structures within the knee can gradually break down. Factors that may contribute to knee pain include:

• Excess weight, which places additional stress on the knee joint
• Repetitive activities or overuse that irritate the tissues supporting the knee
• A history of arthritis

Arthritis and Other Medical Conditions

Several medical conditions can cause knee discomfort, including:

• Osteoarthritis
• Rheumatoid arthritis
• Lupus
• Gout
• Infections
• Baker cysts
• Bone cancers (less common)

Osteoarthritis is especially common after age 50. Degenerative meniscal tears, which may occur along with arthritis, can also cause pain, swelling, clicking or locking of the knee.

Injuries and Overuse

Injuries and repetitive strain are among the most frequent causes of knee pain. Common examples include:

• Sprains
• Ligament tears
• Meniscus injuries
• Fractures
• Kneecap dislocations
• Bursitis
• Tendinitis
• Iliotibial band syndrome
• Patellofemoral syndrome

Certain Symptoms May Be Associated With Specific Conditions

• Redness and warmth, which can occur with bursitis or gout
• Pain and swelling just below the kneecap, which are common in adolescents and young adults with Osgood-Schlatter disease

Understanding the underlying cause of knee pain can help guide the most appropriate treatment plan and support better long-term relief.

How To Diagnose Knee Pain?

One of our doctors will begin by reviewing your symptoms and performing a physical examination of your knee. Imaging studies, such as X-rays or MRI scans, may be ordered to help identify the source of the pain and guide treatment decisions.

If your discomfort is mild, you may be able to monitor your symptoms and try simple self-care measures at home. However, if your symptoms persist or do not improve with home treatment, it is important to seek a professional evaluation to ensure an accurate diagnosis and appropriate care.

At OrthoMO, fellowship-trained orthopedic physicians provide prompt evaluations for knee pain and other musculoskeletal conditions. Whether your symptoms are caused by an injury, arthritis or overuse, the team offers personalized care to help diagnose the problem and help get you back to a more active lifestyle.

What Doctor To See for Knee Pain?

If you're experiencing persistent knee pain, it's a good idea to start with your primary care provider, who can evaluate your symptoms and determine whether you should see an orthopedic knee doctor. Because knee pain can have many causes, including arthritis, injuries and other joint conditions, you may be referred to an orthopedic doctor for degenerative conditions or a rheumatologist if inflammatory arthritis or another complex joint disease is suspected. Once a diagnosis is made, your care team can help you understand your condition, explain your treatment options and provide guidance on managing knee pain in your daily life.

At OrthoMO in Creve Coeur and Cape Girardeau, MO, experienced orthopedic doctors diagnose and treat a wide range of knee conditions, from arthritis and meniscus tears to ligament injuries and overuse-related pain through conservative treatments or orthopedic knee surgery procedures.

How To Treat Knee Pain?

The right knee pain treatment depends on the underlying cause. After evaluating your symptoms and making a diagnosis, your provider may recommend one or more of the following treatment options to help relieve pain, improve function and support long-term joint health.

Medications to Reduce Pain and Inflammation

For knee pain accompanied by swelling, anti-inflammatory medications such as aspirin or ibuprofen may help relieve discomfort. Some people may also benefit from lifestyle changes that support a healthy inflammatory response, including eating a diet rich in fruits and vegetables while limiting processed foods, saturated fats and added sugars.

Exercise and Physical Therapy

Exercise plays an important role in managing many causes of knee pain, especially osteoarthritis. Strengthening the muscles around the knee, particularly the quadriceps and glutes, can improve stability, reduce stress on the joint and support
