Hello, 小江. Thank you for your question regarding the pain you experience in your left knee, particularly when descending stairs. It's important to understand that knee pain can arise from various underlying issues, and the specific location and nature of your pain can provide valuable clues about its cause.


Possible Causes of Knee Pain When Descending Stairs
1. Patellofemoral Pain Syndrome (PFPS): This condition is characterized by pain around the kneecap (patella) and is often exacerbated by activities that put stress on the knee joint, such as descending stairs. It can result from overuse, muscle imbalances, or improper tracking of the kneecap.

2. Iliotibial Band Syndrome (ITBS): The iliotibial band is a thick band of tissue that runs along the outside of the thigh from the hip to the knee. When this band becomes tight or inflamed, it can cause pain on the outer side of the knee, especially during activities like going down stairs.

3. Meniscus Tear: The meniscus is a cartilage structure that acts as a cushion between the femur (thigh bone) and tibia (shin bone). A tear in the meniscus can lead to pain, especially during twisting movements or when bearing weight on the knee, such as when descending stairs.

4. Chondromalacia Patella: This condition involves the softening and breakdown of the cartilage on the underside of the kneecap. It can cause pain during activities that put pressure on the knee, including stair descent.

5. Osteoarthritis: As we age, the cartilage in our joints can wear down, leading to osteoarthritis. This condition can cause pain, stiffness, and swelling in the knee, particularly during activities that involve bending the knee, such as going down stairs.


Solutions and Management Strategies
1. Rest and Activity Modification: Since you mentioned that you are not engaging in vigorous exercise, it's essential to continue avoiding activities that exacerbate your pain. If descending stairs is painful, consider using elevators or ramps when possible.

2. Physical Therapy: A physical therapist can assess your knee and develop a tailored exercise program to strengthen the muscles around the knee, improve flexibility, and correct any biomechanical issues contributing to your pain.

3. Ice Therapy: Applying ice to the affected area after activities can help reduce inflammation and alleviate pain. Aim for 15-20 minutes of ice application, several times a day.

4. Pain Relief Medications: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, can help manage pain and reduce inflammation. However, consult with your healthcare provider before starting any medication.

5. Knee Bracing: A knee brace can provide support and stability to the knee joint, potentially alleviating pain during activities like stair descent.

6. Gradual Return to Activity: Once your pain subsides, gradually reintroduce activities, starting with low-impact exercises such as swimming or cycling, which place less stress on the knee.

7. Consultation with a Specialist: If your symptoms persist despite conservative management, it may be beneficial to consult an orthopedic specialist. They may recommend imaging studies, such as X-rays or MRI, to assess the condition of your knee and determine the best course of action.


Conclusion
Knee pain when descending stairs can be frustrating and limiting. Understanding the potential causes and implementing appropriate management strategies can significantly improve your quality of life. Always listen to your body and seek professional advice when needed. If your symptoms continue to recur, further evaluation by a healthcare professional is essential to rule out any serious underlying conditions. Take care, and I hope you find relief soon!
