The patellar tendon receives maximum tensile force in the knee flexion angle range of 45 to 60 degrees. Repetitive movements within this range, such as descending stairs, squatting, and deep lunges, are particularly dangerous during the acute phase. Repetitive walking on hard surfaces (concrete or marble), worn-out shoes without cushioning, and weight gain are also external factors that increase the load on the patellar tendon. Applying an ice pack (15–20 minutes) after exercise helps reduce reactive edema. In Korean medicine, maintaining the same posture for a long time is believed to cause a blockage of Qi and blood in one place. Squatting for extended periods causes stagnation at the point where Qi and blood pathways intersect in the front of the knee, exacerbating pain and swelling. At Dongjedang, we provide guidance on correcting daily posture and movement patterns during treatment, and use acupuncture to unblock Qi and blood, ensuring that daily movements do not interfere with treatment.
