Hiking downhill? Knee pain could signal osteoarthritis

Taipei – Enjoying a hike on a pleasant day is a popular pastime, with trails like those on Taipei's Four Beasts Mountains offering scenic beauty. However, for many, the descent can bring discomfort. Chinese medicine practitioner Wang Da-yuan warns that persistent knee pain and stiffness during downhill treks may signal the onset of osteoarthritis (OA).

Osteoarthritis is characterized by the gradual structural changes in joint cartilage and surrounding tissues. While age is a factor, other risks include obesity, previous joint injuries, insufficient muscle strength, and repetitive stress on the joints. Common symptoms include pain and stiffness during movement, swelling, redness, and audible friction sounds within the joint.

Wang emphasizes that the downhill portion of a hike is particularly taxing on the knees. The repetitive bending and stress can significantly aggravate existing discomfort. He likens the sensation to the knees "protesting" with each step, a clear warning sign that requires attention.

From a traditional Chinese medicine perspective, these symptoms fall under the category of "bi syndrome," which involves pain and obstruction in the body. Treatment is individualized based on the location of pain and the patient's overall condition, whether it involves cold, heat, dampness, or deficiencies in Qi and blood. Acupuncture and infrared therapy targeting specific acupoints, along with herbal remedies like Duhu Jisheng Tang or Juan Bi Tang, are often employed to improve joint function and alleviate symptoms.

To continue enjoying mountain activities safely, Wang advises strengthening the thigh and gluteal muscles, maintaining a healthy weight, and performing thorough warm-ups before hiking. During descents, hikers should slow their pace, shorten their stride, and consider using trekking poles to distribute the load. Persistent or severe knee pain, swelling, or difficulty walking warrants professional medical evaluation and treatment.
