Knee pain

Hello Doctor: Since the beginning of this year, I have occasionally experienced knee pain, so I have been taking glucosamine in hopes of alleviating the pain or aiding in recovery.
However, due to my work, which requires frequent walking, the pain tends to improve for a while and then recur.
Last month, after moving, the knee pain became more severe, especially when getting up after sitting for a long time or standing and walking.
However, the pain tends to subside after some time.
I am still taking glucosamine, but it doesn't seem to be very effective.
I would like to ask if this condition is due to joint degeneration? Is recovery possible? Or how should I strengthen my care? Thank you!

DEAR SOPHIE: Hello, since you did not provide the cause of your first knee pain episode, it is difficult to make a clear assessment.
Generally speaking, at your age, degenerative knee osteoarthritis is rarely seen at such an early stage.
Typically, degenerative knee osteoarthritis is associated with older age, long-term heavy work, and in younger individuals, it is more related to a history of previous injuries.
You mentioned that the pain is more likely to occur after prolonged sitting or standing, which may be related to the surrounding muscles and ligaments; however, there is usually a history of prior injury.
Glucosamine has been shown to be more effective in reducing cartilage wear, and some reports suggest it may provide about a 30% pain relief effect.
Therefore, if the glucosamine treatment did not yield satisfactory results, it may be due to an incorrect indication.
I recommend that you consult with an orthopedic specialist or a rehabilitation physician for a definitive diagnosis.
Wishing you safety and health.
Sincerely, Dr.
Hou Yu-Chang, Director of the Traditional Chinese Medicine Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

Knee pain is a common issue that can arise from various causes, including degenerative changes, injuries, and overuse. Understanding the underlying reasons for your knee pain is crucial for effective treatment and prevention. Based on your description, it seems that your knee pain may be related to degenerative changes, possibly osteoarthritis, especially given your age and the nature of your symptoms.

Causes of Knee Pain
1. Osteoarthritis: This is the most common form of arthritis, characterized by the wear and tear of cartilage, leading to pain, stiffness, and swelling. Symptoms often worsen with activity and improve with rest. The pain you experience after prolonged sitting or standing is typical of osteoarthritis.

2. Tendinitis: Inflammation of the tendons around the knee can cause pain, especially during activities that involve repetitive motion or strain, such as walking or climbing stairs.

3. Meniscus Tears: The meniscus is a cartilage structure that acts as a cushion between the femur and tibia. Tears can occur due to sudden twisting motions or degenerative changes, leading to pain and a sensation of the knee locking or giving way.

4. Ligament Injuries: Injuries to the ligaments, such as the ACL or MCL, can also cause pain and instability in the knee.

5. Bursitis: Inflammation of the bursae (small fluid-filled sacs that cushion the knee joint) can lead to localized pain, especially when bending or straightening the knee.

Treatment Options
1. Medication: Over-the-counter pain relievers like acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and reduce inflammation. Since you are taking glucosamine supplements, it's important to note that while some people find relief, the scientific evidence is mixed regarding its effectiveness.

2. Physical Therapy: Engaging in a physical therapy program can strengthen the muscles around the knee, improve flexibility, and enhance overall function. A physical therapist can design a personalized exercise regimen tailored to your needs.

3. Weight Management: Maintaining a healthy weight is crucial, as excess weight puts additional stress on the knee joints. Losing even a small amount of weight can significantly reduce pain and improve function.

4. Activity Modification: Avoid activities that exacerbate your pain, such as excessive stair climbing or prolonged standing. Incorporate low-impact exercises like swimming or cycling, which can help maintain fitness without stressing the knees.

5. Heat and Cold Therapy: Applying heat can help relax and soothe stiff muscles, while cold packs can reduce swelling and numb sharp pain.

6. Injections: In some cases, corticosteroid injections may be recommended to reduce inflammation and provide temporary relief. Hyaluronic acid injections are another option that may help lubricate the joint.

7. Surgery: If conservative treatments fail and pain persists, surgical options such as arthroscopy, osteotomy, or knee replacement may be considered, depending on the severity of the damage.

Prevention Tips
1. Regular Exercise: Engage in regular, low-impact exercises to strengthen the muscles around the knee and maintain joint flexibility.

2. Proper Footwear: Wearing supportive shoes can help reduce stress on the knees.

3. Warm-Up and Cool Down: Always warm up before physical activity and cool down afterward to prevent injuries.

4. Listen to Your Body: Pay attention to pain signals and avoid pushing through pain during activities.

5. Stay Hydrated and Maintain a Balanced Diet: Proper nutrition supports joint health. Foods rich in omega-3 fatty acids, antioxidants, and vitamins can help reduce inflammation.

In conclusion, while your symptoms may suggest degenerative changes in the knee, a thorough evaluation by a healthcare professional is essential for an accurate diagnosis and tailored treatment plan. Continuing to manage your symptoms through a combination of medication, physical therapy, and lifestyle modifications can significantly improve your quality of life and knee function. If your symptoms persist or worsen, consider seeking further medical advice for a comprehensive assessment.
